Réunion

History

The island has been inhabited since the 17th century, when people from France and Madagascar settled there. Slavery was abolished on 20 December 1848 (a date celebrated yearly on the island), when the Second Republic that had been established months earlier by the February Revolution abolished slavery in the French colonies. However, indentured workers continued to be brought to Réunion from South India, among other places. The island became an overseas department of France in 1946.

Early history

Not much is known of Réunion's history before the arrival of the Portuguese in the early 16th century. Arab traders were familiar with it by the name Dina Morgabin, "Western Island" (likely Arabic: دنية مغربي Daniyah/ Maghribīy). The island is possibly featured on a map from 1153 AD by Al Sharif el-Edrisi. The island might also have been visited by Swahili or Austronesian (ancient Indonesian–Malaysian) sailors on their journey to the west from the Malay Archipelago to Madagascar.

The first European discovery of the area was made around 1507 by Portuguese explorer Diogo Fernandes Pereira, but the specifics are unclear. The uninhabited island might have been first sighted by the expedition led by Dom Pedro Mascarenhas, who gave his name to the island group around Réunion, the Mascarenes. Réunion itself was dubbed Santa Apolónia after a favourite saint, which suggests that the date of the Portuguese discovery could have been 9 February, her feast day. Diogo Lopes de Sequeira is said to have landed on the islands of Réunion and Rodrigues in 1509.

Isle Bourbon (1642–1793)

By the early 1600s, nominal Portuguese rule had left Santa Apolónia virtually untouched. The island was then occupied by France and administered from Port Louis, Mauritius. Although the first French claims date from 1638, when François Cauche and Salomon Goubert visited in June 1638, the island was officially claimed by Jacques Pronis of France in 1642, when he deported a dozen French mutineers to the island from Madagascar. The convicts were returned to France several years later, and in 1649, the island was named Île Bourbon after the House of Bourbon. Colonisation started in 1665, when the French East India Company sent the first settlers.

The French colonists developed a plantation economy founded on the cultivation of coffee and sugar by use of slave labor. From the 17th to the 19th centuries, French colonisation, supplemented by importing Africans, Chinese, and Indians as workers, contributed to ethnic diversity in the population. From 1690, most of the non-Europeans on the island were enslaved. Of the 80,000 slaves imported to Réunion and Mauritius between 1769 and 1793, 45% were provided by slave traders of the Sakalava people in North West Madagascar, who raided East Africa and the Comoros for slaves, and the rest were provided by Arab slave traders who bought slaves from Portuguese Mozambique and transported them to Réunion via Madagascar.

French Revolutionary and Napoleonic Wars (1793–1814)

On 19 March 1793, during the French Revolution, the island's name was changed to Réunion in homage to the meeting of the Federates of Marseille and the National Guards of Paris, during the march on the Tuileries Palace on 10 August 1792, and to erase the name of the Bourbon dynasty.

The National Convention abolished slavery in French colonies on 4 February 1794, though this was rejected by authorities in Réunion and the Isle de France. A delegation accompanied by military forces, charged with imposing the abolition of slavery, arrived on Isle Bourbon on 18 June 1796, only to be immediately expelled by local authorities, who were pressured by the island's overwhelming pro-slavery colonial population. Napoleon, who came to power in France in 1799 as First Consul, legally supported the continuation of slavery in Réunion in the Law of 20 May 1802. On 26 September 1806, the island was renamed Isle Bonaparte.

Following a series of cyclones and floods between 1806 and 1807, coffee cultivation on the island declined rapidly and was replaced by sugarcane in response to increasing demand from France, which had lost the colony of Saint-Domingue in 1803. During the Mauritius campaign of 1809–1811, the island was invaded by British forces on 7 July 1810 and its governor, General Jean-Chrysostôme Bruneteau de Sainte-Suzanne, capitulated two days later. The island fell under British occupation until the end of the Napoleonic period, with the British restoring the old name of Isle Bourbon.

Colony of Bourbon, then Réunion (1814–1946)

Bourbon Island was returned to the French under the Treaty of Paris of 1814. The slave trade openly operated in the colony after French rule was restored, and despite international condemnation, Bourbon Island imported 2,000 slaves every month during the 1820s, mostly from the Swahili coast or Quelimane in Portuguese Mozambique. In 1841, Edmond Albius' discovery of hand-pollination of vanilla flowers enabled the island to soon become the world's leading vanilla producer. The cultivation of geranium, whose essence is widely used in perfumery, also took off. From 1838 to 1841, Rear-Admiral Anne Chrétien Louis de Hell was governor of the island. A profound change in society and mentality linked to the events of the last ten years led the governor to present three emancipation projects to the Colonial Council.

On 9 June 1848, after the arrival of news of the French Revolution of 1848 from Europe, governor Joseph Graëb announced the proclamation of the French Republic in Saint-Denis, and on that same day the island was renamed "Réunion", the name it had already held between 1793 and 1806. The establishment of the Republic was met with coldness and distrust by the white plantocracy due to the professed abolitionism of the new Republican authorities in Paris. On 18 October 1848, the new Commissioner of the Republic Joseph Napoléon Sébastien Sarda Garriga, sent from Paris to replace Graëb, announced in Saint-Denis the abolition of slavery in Réunion, effective on 20 December 1848 (20 December has been an official holiday in Réunion since then). Louis Henri Hubert Delisle became its first Creole governor on 8 August 1852, and remained in this position until 8 January 1858.

After abolition, many foreign workers came as indentured workers. Slavery was replaced by a system of contract labor known as engagés, which lasted from 1848 until 1864. In practice, an illegal slave trade was conducted in which slaves were acquired from Portuguese Mozambique and Zanzibar and then trafficked to Réunion via the Comoros slave trade. They were officially called engagés to avoid the anti-slavery British blockade of Africa.

The opening of the Suez Canal in 1869 reduced the importance of the island as a stopover on the East Indies trade route and caused a shift in commercial traffic away from the island. Europe increasingly turned to sugar beet to meet its sugar needs. Despite the development policy of the local authorities and the recourse to compromise, the economic crisis became evident from the 1870s onwards. However, this economic depression did not prevent the modernization of the island, with the development of the road network, the creation of the railroad, and the construction of the artificial harbor of the Pointe des Galets. These major construction projects offered a welcome alternative for agricultural workers.

During World War II, Réunion was under the control of Vichy France until 30 November 1942, when Free French forces disembarked from the destroyer Léopard and liberated the colony.

Modern history (1946–1999)

Réunion became a département d'outre-mer (overseas département) of France on 19 March 1946. INSEE assigned to Réunion the department code 974, and the region code 04 when regional councils were created in 1982 in France, including in existing overseas departments that also became overseas regions.

Over about two decades in the late 20th century (1963–1982), 1,630 children from Réunion were relocated to rural areas of metropolitan France, particularly to Creuse, ostensibly for education and work opportunities. That programme was led by influential Gaullist politician Michel Debré, who was an MP for Réunion at the time. Many of these children were abused or disadvantaged by the families with whom they were placed. Known as the Children of Creuse, they and their fate came to light in 2002 when one of them, Jean-Jacques Martial, filed suit against the French state for kidnapping and deportation of a minor. Other similar lawsuits were filed over the following years, but all were dismissed by French courts and finally by the European Court of Human Rights in 2011.

By the 1990s, Réunion was transitioning from its traditional sugarcane-centered economy to service and tourism sectors. The opening of Pierrefonds Airport near Saint-Pierre in 1998 catalysed visitor growth. Within a few years, tourism revenues surpassed those of sugar production: by 2000, nearly 426,000 tourists visited annually, transforming economic patterns especially along the north and west coasts, and prompting the creation of Creole heritage villages to strengthen cultural tourism.

Efforts to adapt to tropical conditions emerged mid-decade. In 1995, an EDF–ADEME–University collaboration produced ECODOM standards for improved passive cooling and energy efficiency in housing. Over 300 pilot homes were built between 1996 and 1998, informing later thermal regulations.

21st century

In 2005 and 2006, Réunion was hit by a crippling epidemic of chikungunya, a disease spread by mosquitoes. According to the BBC News, 255,000 people on Réunion had contracted the disease as of 26 April 2006. The neighbouring islands of Mauritius and Madagascar also suffered epidemics of this disease during the same year.

Cyclone Garance struck Réunion in March 2025, killing at least four people and leaving over 160,000 without power. The cyclone, with winds up to 230 km/h, made landfall in the north of the island before moving southwest, causing flash floods, mudslides, and structural damage. Authorities lifted a red alert after the storm weakened. Thousands were left without drinking water or internet, and flights were temporarily halted. French Prime Minister François Bayrou urged caution, while residents described the cyclone as one of the most powerful they had experienced.

Politics

Réunion sends seven deputies to the French National Assembly and three senators to the Senate.

Status

Réunion is an overseas department and region of France (known in French as a département et région d'outre-mer, DROM) governed by article 73 of the Constitution of France, under which the laws and regulations are applicable as of right, as in metropolitan France.

Thus, Réunion has a regional council and a departmental council. These territorial entities have the same general powers as the departments and regions of metropolitan France, albeit with some adaptations. Article 73 of the constitution provides for the possibility of replacing the region and the department by a single territorial entity, but, unlike French Guiana or Martinique, there are currently no plans to do so. Unlike the other DROMs, the constitution explicitly excludes Réunion from the possibility of receiving authorization from Parliament to set certain rules itself, either by law or by the national executive. The state is represented in Réunion by a prefect. The territory is divided into four districts (Saint-Benoît, Saint-Denis, Saint-Paul, and Saint-Pierre). Réunion has 24 municipalities organized into 5 agglomeration communities. From the point of view of the European Union, Réunion is considered an "outermost region".

Geopolitics

The positioning of Réunion Island has given it a more or less important strategic role depending on the period.

Already at the time of the India Route or Route des Indes, Réunion was a French possession located between Cape Town and the Indian trading posts, although far from the Mozambique Channel. Isle Bourbon (its name under the Ancien Régime) was not, however, the preferred position for trade and military. Governor Labourdonnais claimed that the Isle de France was a land of opportunity, thanks to its topography and the presence of two natural harbours. He intended Isle Bourbon to be a depot or an emergency base for Isle de France.

The opening of the Suez Canal diverted much of the maritime traffic from the southern Indian Ocean and reduced the strategic importance of the island. This decline is confirmed by the importance given to Madagascar, which was later colonized.

Today, the island, the seat of a defense and security zone, is the headquarters of the French Armed Forces of the Southern Indian Ocean Zone (FAZSOI), which brings together French Army units stationed in Réunion and Mayotte. Réunion is also a base for the so-called Frenchelon signal intelligence system, whose infrastructure includes a mobile listening and automatic search unit. Saint-Pierre is also the headquarters of the mostly uninhabited French Southern and Antarctic Lands (Terres australes et antarctiques françaises, TAAF). Because of France's possession of Réunion, France is a member of the Indian Ocean Commission, which also includes the Comoros, Madagascar, Mauritius, and the Seychelles.

Administrative divisions

Administratively, Réunion is divided into 24 communes (municipalities) grouped into four arrondissements. It is also subdivided into 25 cantons, meaningful only for electoral purposes at the departmental or regional level. It is a French overseas department, hence a French overseas region. The low number of communes, compared with French metropolitan departments of similar size and population, is unique: most of its communes encompass several localities, sometimes separated by significant distances.

Municipalities (communes)

The communes voluntarily grouped themselves into five groups for cooperating in some domains, apart from the four arrondissements to which they belong for purposes of national laws and executive regulation. After some changes in their composition, name and status, all of them operate with the status of agglomeration communities, and apply their own local taxation (in addition to national, regional, departmental, and municipal taxes) and have an autonomous budget decided by the assembly representing all member communes. This budget is also partly funded by the state, the region, the department, and the European Union for some development and investment programmes. Every commune in Réunion is now a member of such an intercommunality, with its own taxation, to which member communes have delegated their authority in various areas.

Foreign relations

Although diplomacy, military, and French government matters are handled by Paris, Réunion is a member of La Francophonie, the Indian Ocean Commission, the International Trade Union Confederation, the Universal Postal Union, the Port Management Association of Eastern and Southern Africa, and the World Federation of Trade Unions in its own right.

Defense

The French Armed Forces are responsible for the defence of the department. These forces also contribute to the defence of other French territories in the region, including Mayotte and the French Southern and Antarctic Lands. About 2,000 regular French troops are deployed in the region, mostly in Réunion, centred on the 2nd Marine Infantry Parachute Regiment. Two CASA CN 235 aircraft, forming air detachment 181 and drawn from the 50th Air Transport squadron, provide a modest air transport and surveillance capability. In 2022, the French Air Force demonstrated a capacity to reinforce the territory by deploying two Rafale fighter aircraft, supported by an A330 MRTT Phénix tanker, from France to Réunion for a regional exercise. By 2030 the French Armed Forces aim to increase the size of the reserve force in Réunion to around half that of the regular force presence.

The French naval presence includes two Floréal-class frigates, Floréal and Nivôse, the icebreaker L'Astrolabe, the patrol and support ship Champlain, Auguste Techer, a new patrol vessel of the Félix Éboué class of patrol vessels, and Le Malin, a former trawler seized by French authorities for illegal fishing and converted into a patrol boat. Two RP10-class harbour tugboats have also been deployed in the territory. The naval aviation element includes up to two AS 365N Dauphin helicopters from Flottille 34F able to embark on the Floréal-class frigates as required. In 2027, the French Navy intends to replace Le Malin with a second vessel of the Félix Éboué class.

About 800 National Gendarmerie, including one mobile squadron and one high mountain platoon, are also stationed in Réunion.

The island is 63 km (39 mi) long; 45 km (28 mi) wide; and covers 2,512 km² (970 mi²). It is above a hotspot in the Earth's crust. The Piton de la Fournaise, a shield volcano on the eastern end of Réunion, rises more than 2,631 m (8,632 ft) above sea level and is sometimes called a sister to Hawaiian volcanoes because of the similarity of climate and volcanic nature. It has erupted more than 100 times since 1640, and is under constant monitoring, most recently erupting on 13 February 2026. During another eruption in April 2007, the lava flow was estimated at 3,000,000 m³ (3,900,000 yd³) per day. The hotspot that fuels Piton de la Fournaise also created the islands of Mauritius and Rodrigues.

The Piton des Neiges volcano, the highest point on the island at 3,070 m (10,070 ft) above sea level, is northwest of the Piton de la Fournaise. Collapsed calderas and canyons are southwest of the mountain. While the Piton de la Fournaise is one of Earth's most active volcanoes, the Piton des Neiges is dormant. Its name is French for "peak of snows", but snowfall on the summit of the mountain is rare. The slopes of both volcanoes are heavily forested. Cultivated land and cities like the capital city of Saint-Denis are concentrated on the surrounding coastal lowlands. Offshore, part of the west coast is characterised by a coral reef system. Réunion also has three calderas: the Cirque de Salazie, the Cirque de Cilaos and the Cirque de Mafate. The last is accessible only on foot or by helicopter.

Geology and relief

Réunion is a volcanic island born some three million years ago with the emergence of the Piton des Neiges volcano. It has an altitude of 3,070.5 m (10,074 ft), the highest peak in the Mascarene Islands and the Indian Ocean. The eastern part of the island is constituted by the Piton de la Fournaise, a much more recent volcano (500,000 years old) which is considered one of the most active on the planet. The emerged part of the island represents only a small percentage (about 3%) of the underwater mountain that forms it.

In addition to volcanism, the relief of the island is very uneven due to active erosion. The centre shelters three vast cirques dug by erosion (Salazie, Mafate and Cilaos), and the slopes of the island are furrowed by numerous rivers digging gullies, estimated at least 600 generally deep and whose torrents cut the sides of the mountains up to several hundred metres deep.

The ancient massif of the Piton des Neiges is separated from the massif of La Fournaise by a gap formed by the plaine des Palmistes and the plaine des Cafres, a passageway between the east and the south of the island. Apart from the plains, the coastal areas are generally the flattest regions, especially in the north and west of the island. The coastline of the wild south is, however, steeper.

Between the coastal fringe and the Hauts, there is a steep transitional zone whose gradient varies considerably before arriving at the ridge lines setting the cirques or the Enclos, the caldera of the Piton de la Fournaise.

Climate

Réunion is characterized by a humid tropical climate, tempered by the oceanic influence of the trade winds blowing from east to west. The climate of Réunion is characterized by its great variability, mainly due to the imposing relief of the island, which produces numerous distinct microclimates.

As a result, there are strong disparities in rainfall between the windward coast in the east and the leeward coast in the west, and in temperature between the warmer coastal areas and the relatively cooler highland areas.

In Réunion, there are two distinct seasons, defined by the rainfall regime:

• a rainy season from January to March, during which most of the year's rain falls;
• a dry season from May to November. However, in the eastern part and the foothills of the volcano, rainfall can be significant even in the dry season;

April and December are transition months, sometimes very rainy but also very dry.

Pointe des Trois Bassins, located on the coast of the commune of Trois-Bassins (west), is the driest station, with a normal annual precipitation of 447.7 mm (17.63 in), while Le Baril, in Saint-Philippe (southeast), is the wettest coastal station, with a normal annual precipitation of 4,256.2 mm (167.57 in).

However, the wettest station is in the highlands of Sainte-Rose, with an average annual rainfall of almost 11,000 mm (430 in), making it one of the wettest places in the world.

Temperatures in Réunion are characterized by their great mildness throughout the year. The thermal amplitude from one season to another is relatively small (rarely exceeding 10 °C or 18 °F), although it is perceptible:

• In the warm season (November to April): average minimums usually range between 21 and 24 °C (70 and 75 °F), and average maximums between 28 and 31 °C (82 and 88 °F), on the coast. At 1,000 m (3,300 ft), average minimums fluctuate between 10 and 14 °C (50 and 57 °F) and average maximums between 21 and 24 °C (70 and 75 °F);
• In the cold season (May to October): temperatures at sea level vary from 17 to 20 °C (63 to 68 °F) for average minimums and from 26 to 28 °C (79 to 82 °F) for average maximums. At 1,000 m (3,300 ft), average minimums range from 8 to 10 °C (46 to 50 °F) and average maximums from 17 to 21 °C (63 to 70 °F).

In mountain towns, such as Cilaos or La Plaine-des-Palmistes, average temperatures range between 12 and 22 °C (54 and 72 °F). The highest parts of the habitat and the natural areas at altitude may suffer some winter frosts. Snow was even observed on the Piton des Neiges and Piton de la Fournaise in 2003 and 2006.

The warmest day on record was set on 30 January 2022. In the cold pole of the Réunion (all-time low −5 °C or 23 °F) Gite de Bellecombe (2,245 m or 7,365 ft AMSL) with a maximum temperature of 25.4 °C (77.7 °F). It beats the previous record of 25.1 °C (77.2 °F) set in 2021.

While a growing number of islands (including "non-sovereign" islands) in the world are concerned about the effects of climate change, the island of Réunion was chosen (along with Gran Canaria in Spain) as an example for a case study of an affected ultra-European peripheral territory, for a study on the adequacy of urban and regional planning tools to the needs and characteristics of these islands (including land use and population density and the regulatory framework).

This work confirmed that urban and peri-urban land use pressures are high and that adaptation strategies are incompletely integrated into land use planning. According to the Institute of Island Studies, there is a dysfunction: "island planning tools often do not take climate change adaptation into account and there is too much top-down management in the decision-making process". Réunion holds the world records for the most rainfall in 12-, 24-, 72- and 96-hour periods, including 1.8 metres (5 ft 11 in) in 24 hours.

Beaches

Réunion hosts many beaches. They are often equipped with barbecues, amenities, and parking spaces. Hermitage Beach is the most extensive and best-preserved lagoon in Réunion Island and a popular snorkelling location. It is a white sand beach lined with casuarina trees under which the locals often organise picnics.

At La Plage des Brisants, a surfing spot, many athletic and leisure activities take place. Each November, a film festival is organised there. Movies are projected on a large screen in front of a crowd.

Beaches at Boucan Canot are surrounded by a stretch of restaurants that particularly cater to tourists. L'Étang-Salé on the west coast is covered in black sand consisting of tiny fragments of basalt. This occurs when lava contacts water, it cools rapidly and shatters into the sand and fragmented debris of various sizes. Much of the debris is small enough to be considered sand. Grand Anse is a tropical white-sand beach lined with coconut trees in the south of Réunion, with a rock pool built for swimmers, a pétanque playground, and a picnic area. Le Vieux Port in Saint Philippe is a green-sand beach consisting of tiny olivine crystals, formed by the 2007 lava flow, making it one of the youngest beaches on Earth.

Environment

Flora

The tropical and insular flora of Réunion Island is characterized by its diversity, a very high rate of endemism, and a very specific structure. The flora of Réunion presents a great diversity of natural environments and species (up to 40 tree species/ha, compared to a temperate forest, which has an average of 5/ha). This diversity is even more remarkable, but fragile, as it differs according to the environment (coastal, low, medium, and high mountain).

Réunion has a very high rate of endemic species, with more than 850 native plants (of natural origin and present before the arrival of humans), of which 232 are endemic to the Réunion (only present on the island), as well as numerous species endemic to the Mascarene archipelago. Finally, the flora of Réunion is distinguished from that of equatorial tropical forests by the low height and density of the canopy, probably due to adaptation to cyclones, and by a very specific vegetation, in particular a strong presence of epiphytic plants (growing on other plants), such as orchids, bromeliads and invasive cacti, but also ferns, lichens, and mosses.

Wildlife

Like its prodigious floral diversity, Réunion is home to a variety of birds such as the white-tailed tropicbird (French: paille en queue). Many of these bird species are endemic to the island, such as the Réunion harrier and Réunion cuckooshrike. Its largest land animal is the panther chameleon, Furcifer pardalis. Much of the west coast is ringed by coral reefs which harbour, among other animals, sea urchins, conger eels, and parrot fish. Sea turtles and dolphins also inhabit the coastal waters. Humpback whales migrate north to the island from the Antarctic waters annually during the Southern Hemisphere winter (June–September) to breed and feed, and can be routinely observed from the shores of Réunion during this season.

Beekeepers began importing European honey bees during the late 19th century, which in turn have bred with the endemic Apis mellifera unicolor subspecies, which originated from Madagascar. 97% of the honey bees on the island are descended from A. m. unicolor; however, their DNA only accounts for 53% of the genetic mixture. In an attempt to prevent the spread of diseases a bee importation ban was imposed in 1982, however in 2017 one or two Varroa destructor mites were brought into the island when a Queen bee was smuggled in by a beekeeper, within 4.5 months the mites had spread throughout the island, causing an increase of annual deaths of colonies from 0.6% to 64%, after initially reaching 85%.

At least 19 species formerly endemic to Réunion have become extinct following human colonisation. For example, the Réunion giant tortoise became extinct after being slaughtered in vast numbers by sailors and settlers of the island.

Marine biodiversity

Despite the small area of coral reefs, the marine biodiversity of Réunion is comparable to that of other islands in the area, which has earned the Mascarene archipelago its inclusion among the top ten global biodiversity "hotspots". Réunion's coral reefs, both flat and barrier, are dominated mainly by fast-growing branching coral species of the genus Acropora (family Acroporidae), which provide shelter and food for many tropical species.

Recent scientific research in Réunion Island indicates that there are more than 190 species of corals, more than 1,300 species of mollusks, more than 500 species of crustaceans, more than 130 species of echinoderms and more than 1,000 species of fish.

Réunion's deeper waters are home to dolphins, killer whales, humpback whales, blue sharks, and a variety of shark species, including whale sharks, coral sharks, bull sharks, tiger sharks, blacktip sharks, and great white sharks. Several species of sea turtles live and breed here.

Between 2010 and 2017, 23 shark attacks occurred in the waters of Réunion, of which nine were fatal. In July 2013, the Prefect of Réunion Michel Lalande announced a ban on swimming, surfing, and bodyboarding off more than half of the coast. Lalande also said 45 bull sharks and 45 tiger sharks would be culled, in addition to the 20 already killed as part of scientific research into the illness ciguatera.

Migrations of humpback whales contributed to a boom of whale watching industries on Réunion, and watching rules have been governed by the OMAR (Observatoire Marin de la Réunion) and Globice (Groupe local d'observation et d'identification des cétacés).

Coral reef

Because the island is relatively young (3 million years old), the coral formations (8,000 years old) are not well developed and occupy a small area compared to older islands, mostly in the form of fringing reefs.

These formations define shallow "lagoons" (rather "reef depressions"), the largest of which is no more than 200 m (660 ft) wide and about 1–2 m (3.3–6.6 ft) deep. These lagoons, which form a discontinuous reef belt 25 km (16 mi) long (i.e. 12% of the island's coastline) with a total area of 12 km² (4.6 sq mi), are located on the west and southwest coast of the island. The most important are those of L'Ermitage (St-Gilles), St-Leu, L'Étang-Salé, and St-Pierre.

Management

Since 2010, Réunion is home to a UNESCO World Heritage Site that covers about 40% of the island's area and coincides with the central zone of the La Réunion National Park. The island is part of the Mascarene forests terrestrial ecoregion.

Gardening and Bourbon roses

The first members of the "Bourbon" group of garden roses originated on this island (then still Isle Bourbon, hence the name) from a spontaneous hybridisation between Damask roses and Rosa chinensis, which had been brought there by the colonists. The first Bourbon roses were discovered on the island in 1817.

Threats to the environment

Among coastal ecosystems, coral reefs are among the richest in biodiversity, but they are also the most fragile.

Nearly one-third of fish species were already considered threatened or vulnerable in 2009, with coral degradation in many places. The causes of this state of affairs are pollution, overfishing, and poaching, as well as anthropogenic pressure, especially linked to the densification of urbanization in coastal areas and the discharge of sewage.

15 species living on Réunion were included in the Red List published by the International Union for Conservation of Nature (IUCN).

Demographics

Historical population

Major metropolitan areas

The most populous metropolitan area is Saint-Denis, which covers six communes (Saint-Denis, Sainte-Marie, La Possession, Sainte-Suzanne, Saint-André, and Bras-Panon) in the north of the island. The three largest metropolitan areas are:

Migration and ethnic groups

At the 2022 census, 79.5% of the inhabitants of Réunion were born on the island, 13.4% were born in Metropolitan France, 2.0% were born in Mayotte, 0.3% were born in the rest of Overseas France, and 4.8% were born in foreign countries (44% of them children of French expatriates and settlers born in foreign countries, such as children of Réunionese settlers born in Madagascar during colonial times; the other 56% immigrants, i.e. people born in foreign countries with no French nationality at birth).

In recent decades, the number of Metropolitan Frenchmen living on the Réunion has increased markedly: only 5,664 natives of Metropolitan France lived in Réunion at the 1967 census, but their numbers were multiplied by more than six in 23 years, reaching 37,516 at the 1990 census, and then tripled in the next three decades, reaching 118,178 at the 2022 census. Native Réunionese, meanwhile, have emigrated increasingly to Metropolitan France: the number of natives of Réunion living in Metropolitan France rose from 16,548 at the 1968 census to 92,354 at the 1990 census to 139,528 at the 2022 census, by which date 16.7% of the natives of Réunion lived outside of the department.

Réunion has received little immigration from places other than metropolitan France since World War II, and by the 2022 census, only 2.7% of its inhabitants were immigrants. This is in contrast to the situation that prevailed from the middle of the 19th century until World War Two when many migrants from India (especially from Tamil Nadu and Gujarat), Eastern Asia (particularly China), and Africa came to Réunion to work in the plantation economy. Their descendants have now become French citizens.

Ethnic groups present include people of African, Asian, European, and Malagasy origin. Local names for these are Yabs, Cafres, Malbars and Chinois. These populations have mixed from the earliest days of the island's colonial history (the first settlers married women from Madagascar and of Indo-Portuguese heritage), resulting in a majority population of mixed race and of "Creole" culture.

It is not known exactly how many people of each ethnicity live in Réunion, since the French census does not ask questions about ethnic origin, which applies in Réunion because it is a part of France per the 1958 constitution. The extent of racial mixing on the island also makes ethnic estimates difficult. According to estimates, Europeans make up roughly one quarter of the population, Malbars make up more than 25% of the population and people of Chinese ancestry form roughly 3%. The percentages for those of African and mixed-race origins vary widely in estimates. Also, a few people of Vietnamese ancestry live on the island.

Tamils are the largest group among the Indian community. The island's Indian-origin Muslims are commonly referred as zarabes.

Creoles (a name given to those born on the island, regardless of ethnic origins) make up the majority of the population. Groups that are not Creole include people recently arrived from Metropolitan France (known as zoreilles) and those from Mayotte and the Comoros, as well as immigrants from Madagascar and Sri Lankan Tamil refugees.

Religion

The predominant religion is Christianity. The Catholic Church has a single jurisdiction, the Diocese of Saint-Denis-de-La Réunion.

According to INSEE, the French National Institute of Statistics and Economic Studies, in 2020, 19% of the population of Réunion didn't declare practicing a religion. 86% of believers practiced some form of Christianity, 12% some form of Hinduism, 7% some form of Islam and 11% a mix of multiple religions. Chinese folk religion and Buddhism have some followers.

Most large towns have a Hindu temple and a mosque.

Ritual

See also: Kabaré (fête) §Les sèrvis kabaré (in French)

There are traditional Réunionnais ceremonial practices (Les sèrvis kabaré, Servis kaf or Servis zansèt) of ancestor veneration arising from Malagasy roots, blended with Malabar, Comorian, European, and Chinese cultural influences. These may be practised by those adhering to the main religions of Christianity, Hinduism and Islam.

Culture

Réunionese culture is a blend (métissage) of European, African, Indian, Chinese and insular traditions. The most widely spoken language, Réunion Creole, derives from French.

Language

French is the sole official language of Réunion. Though not official, Réunion Creole is widely spoken alongside French. Creole is commonly used for informal purposes, whereas the official language for administrative purposes, as well as education, is French.

Other languages spoken on Réunion include: Comorian varieties (especially Shimaore) and Malagasy, by recent immigrants from Mayotte and Madagascar; Mandarin, Hakka and Cantonese by members of the Chinese community; Indian languages, mostly Tamil, Gujarati and Hindi; and Urdu, spoken by a small community of Muslims. These languages are generally spoken by immigrants, as those born on the island tend to use French and Creole.

Cantonese, Arabic and Tamil are offered as optional languages in some schools.

Music and dance

Two forms make up the musical tradition of Réunion Island. One, the sega, is a Creole variant of the quadrille; the other, the maloya, like the American blues, comes from Africa, carried by the nostalgia and pain of enslaved people uprooted and deported from their homeland. Sega is present on other islands, while maloya is traditional only in Réunion.

The sega is a disguised ballroom dance to the rhythm of traditional Western instruments (accordion, harmonica, guitar, etc.), and stems from the wider colonial society at the time. It is still the typical ballroom dance of the islands of Réunion, Rodrigues, Seychelles, and the Mascarene archipelago in general. Mauritian sega and Rhodesian sega also continue.

The slaves' maloya, a ritual dance full of melodies and gestures, was performed, often clandestinely, at night around a bonfire; the few instruments that accompanied it were made of plants (bamboo, gourds, etc.). Performance was often an underground activity on plantations as slaveholders disapproved of this cultural expression by the enslaved. From the 1960s, it was suppressed by the French government, which feared its association with Réunionnais pro-autonomy movements and with communism. The sometimes controversial lyrics reminded France of its slave-owning past and underlined the damage this colonial era did to human beings; in the course of the island's history, Maloya artists and kabar (French: kabaré; gatherings) were banned by authorities. Maloya troupes continued to perform in the face of official repression: along with their artistic expression, they wanted to perpetuate the memory of the slaves, their suffering, and their uprooting. The French government's attitude to Maloya did not alter until 1981, when François Mitterrand became president.

Every 20 December, the inhabitants of Réunion celebrate Réunion Freedom Day. This celebration, also known as the Fête des Cafres (or in Réunion Creole French: Fet' Kaf, also, 20 desamb), commemorates the proclamation of the final abolition of slavery by governor Joseph Sarda for the French Second Republic in 1848. Numerous concerts are organized, most of them free, as well as costume parades and dance shows such as merengue, for example.

With the institution of a public holiday to celebrate the abolition of slavery, maloya has received official and wider cultural recognition; it is regularly played on public radio and in many discotheques and dance parties. A revival of maloya, beginning in the 1970s and particularly identified with musician Danyèl Waro, a protégé of Firmin Viry, raised its cultural status. Groups began to make modern versions, styles, and arrangements, such as maloggae and other electric maloya.

Some of Réunion's emblematic maloya artists and groups include: Groupe folklorique de La Réunion; Kalou Pilé; Baster; Ousanousava; Ziskakan; Pat'Jaune; Danyèl Waro; and Tisours. One of the most revered Maloya singers was Lo Rwa Kaf. Born in Sainte-Suzanne, he was one of the first to sing Maloya. When he died in 2004, many people were present at his funeral.

In 2008, the artist and musician Brice Guilbert made a video entitled La Réunion. In this clip, we see him crossing all the landscapes of the island.

In the field of contemporary dance, the choreographer Pascal Montrouge, who directs the only company in France that has a double headquarters in Saint-Denis de La Réunion and Hyères, reinforces the sense of his vision of identity. In 2007, the city of Saint-Denis de La Réunion entrusted him with the artistic direction of its Saint-Denis Danses festival.

The island is home to the regional conservatory of Réunion, which has four teaching centres and was created in 1987 under the impetus of the then president of the region, Pierre Lagourgue. Today, although traditional dances are not forgotten in the conservatoires (which teach dance, music, and theatre), the dances taught are classical dance, contemporary dance, and Bharata natyam dance. These students regularly have the opportunity to dance with choreographers from Réunion, such as Didier Boutiana cie "Konpani Soul city", Soraya Thomas cie "Morphose" or Éric Languet cie "Danse en l'R". These different local companies allow the inhabitants of Réunion to dance professionally.

Urban culture has also made its appearance, following the trends and influences of metropolitan France and the United States. Thus, hip-hop culture is developing, but also ragga dancehall, with KM David or Kaf Malbar being the figurehead of this new movement, influencing the young generation all over the island, with their songs spread by MP3 or the internet. Many young artists are trying to "break through" in this music, whose industry is developing reasonably well, locally but also internationally, and has nothing to envy from the precursors of French dancehall.

Cuisine

Always accompanied by rice, the most common dishes are carry (sometimes spelled cari), a local version of Indian curry; rougail; and civets (stews). Carry is made with a base of onion, garlic and spices such as turmeric (called "safran péi" on the island), on which fish, meat and eggs are fried; tomato is then added. Dishes can also be flavoured with ginger; the peel of a combava is often prized. Chop suey (with rice, not pasta) and other Asian dishes such as pork with pineapple.

Some examples of popular Réunionese dishes include:

• Achards (inspired by achaar)
• Bouchon
• Cabri massalé
• Cari poulet
• Rougail dakatine
• Rougail morue
• Rougail saucisse

In general, there are few dishes without meat or fish, so there are few vegetarian options. One of them is chouchou chayote gratin. Otherwise, mainly poultry is consumed. One of the local specialties is tangue civet (of the hedgehog family).

Sport

Moringue is a popular combat/dance sport similar to capoeira. There are several famous Réunionese sportsmen and women like the handballer Jackson Richardson, as well as the karateka Lucie Ignace. Réunion has several contributions to worldwide professional surfing. It has been home to notable pro surfers including Jeremy Flores, Johanne Defay, and Justine Mauvin. Famous break St Leu has been host to several world surfing championship competitions. Since 1992, Réunion has hosted several ultramarathons under the umbrella name of the Grand Raid. As of 2018, four different races compose the Grand Raid: the Diagonale des Fous, the Trail de Bourbon, the Mascareignes, and the Zembrocal Trail. Annual athletics Meeting de la Réunion is held at the Stade Paul Julius Bénard by the governing body Ligue Réunionnaise d'athlétisme.

Football

Football (soccer) is the most popular sport. With more than 30,000 licensed players for a population exceeding 850,000 inhabitants, it remains the sport of choice for young people. Although the highest level of competition, called the First Division of Réunion, is equivalent to a division d'honneur in metropolitan France (DH), all the youngsters hope to play at the highest level one day.

This has been the case for players such as Laurent Robert, Florent Sinama-Pongolle, Guillaume Hoarau, Dimitri Payet, Benoit Tremoulinas, Melvine Malard (the only six Reunionese to have played for the French national team), Bertrand Robert, Thomas Fontaine, Ludovic Ajorque, Fabrice Abriel (of Réunion descent) and Wilfried Moimbe (of Réunion descent), to name but a few. The territory has its own team, the Réunion national football team.

Architecture

Structurally, the local Creole house is said to be symmetrical. In fact, in the absence of an architect, workers would draw a line on the ground and build two identical parts on each side, resulting in houses of essentially rectangular shape. The veranda is an important element of the house. It is an outdoor terrace built on the front of the house, as it allows to show its richness to the street. A Creole garden completes the house. It is composed of local plants found in the forest. There is usually a greenhouse with orchids, anthuriums, and different types of ferns.

The Villa Déramond-Barre is a Creole architectural model of great heritage interest.

Media

Broadcasting

Réunion has a local public television channel, Réunion 1ère, which now forms part of France Télévision, and also receives France 2, France 3, France 4, France 5, and France 24 from metropolitan France, as well as France Ô, which shows programming from all of the overseas departments and territories. There are also two local private channels, Télé Kréol and Antenne Réunion.

It has a local public radio station, formerly Radio Réunion, but now known as Réunion 1ère, like its television counterpart. It also receives the Radio France networks France Inter, France Musique and France Culture. The first private local radio station, Radio Freedom, was introduced in 1981. They broadcast daily content about weather and local services.

Newspapers

There were three daily newspapers published locally. In 2024, one closed. Of the remaining two, one is now produced online only. There are other – weekly and monthly – publications in Réunion, including general interest and television magazines.

The dailies:

• Journal de l'île de La Réunion, founded in 1951, it closed in 2024 after being placed into bankruptcy ("judicial liquidation") on 31 July.
• Le Quotidien de La Réunion, founded 1976
• Témoignages, founded 1944; online only since 2013

Cinema

Present on the island since 1896, it is marked by its insularity and its geographical distance from metropolitan France. In the absence of the Centre national de la cinématographie (CNC), it has developed specific distribution and dissemination networks. Its landscapes first served as a natural backdrop for many film and television productions, and film events, such as festivals, multiplied there. Digital technology now facilitates the development of local productions, most of which reflect the particularities of a multicultural and multilingual society.

The Réunion Film festival (festival du film de La Réunion) was created in 2005 and is chaired by Fabienne Redt. The festival presented first and second feature films by French directors. The 10th and last edition took place in 2014 in partnership mainly with the TEAT Champ Fleuri (Saint-Denis) and the city of Saint-Paul.

In the Port, the International Film Festival of Africa and the Réunion Islands (Festival international du film d'Afrique et des îles de La Réunion) was also held.

Among the existing film festivals is the Réunion Island Adventure Film Festival (13 editions), which awards prizes to adventure films.

In Saint-Philippe, the Festival Même pas peur, Réunion's international fantasy film festival, has been held since 2010.

In Saint-Pierre, there are two festivals: Écran Jeunes (25th edition in 2019) and the Festival du Film Court de Saint-Pierre, directed by Armand Dauphin (3rd edition in 2019).

Internet

The internet situation in Réunion was once limited by its insularity and its distance from mainland France, which led to delays in technological development. Today, the situation has reversed: the region now has a relatively efficient internet infrastructure and is among the French departments most extensively connected by fibre optics.

Internet access is available through ADSL (offered by four operators), fibre optic service (three operators), and cellular data via 4G and 5G networks (the latter currently being tested in Saint-Denis).

Réunion’s domain names use the suffix .re. The region has built a fibre-optic backbone network for operators, relying partly on EDF’s very high voltage G@zelle cables, partly on the region’s own fibre, and partly on Hertzian links for the most remote areas. This network is operated by the public service company La Réunion Numérique.

Economy

In 2019, the GDP of Réunion at market exchange rates, not at PPP, was estimated at 19.5 billion euros (US$21.8 bn) and the GDP per capita (also at market exchange rates) was 22,629 euros (US$25,333), the highest in sub-Saharan Africa, but only 61.7% of metropolitan France's GDP per capita that year, and 73.5% of the metropolitan French regions outside the Paris Region.

Before the 2008 financial crisis, the economy of Réunion was in a process of catching up with the rest of France. From 1997 to 2007, the economy of Réunion grew by an average of +4.6% per year in real terms, and the GDP per capita rose from 53.7% of metropolitan France's level in 2000 to 61.6% of metropolitan France in 2007. The Great Recession that followed the 2008 financial crisis greatly affected Réunion whose economy came to a standstill in 2008, then experienced two years of recession in 2009 and 2010, followed by three years of stagnation (2011–2013). By 2013, the GDP per capita of Réunion had fallen back to 60.6% of metropolitan France's level.

Economic growth returned in 2014. The economy grew by an average of +2.9% per year in real terms from 2014 to 2017, and the GDP per capita of Réunion rose to 62.4% of metropolitan France's GDP per capita by 2017, its highest level ever. The economy slowed down in 2018, growing at only +1.7% due in part to the yellow vests protests which paralyzed the Réunionese economy at the end of 2018, before recovering to +2.2% in 2019. As a result of this slower growth since 2018, the GDP per capita of Réunion fell back slightly compared to metropolitan France's, standing at 61.7% of metropolitan France's level in 2019.

Réunion was affected by the COVID-19 pandemic in 2020, leading to a massive recession of -4.2% that year according to provisional estimates, the largest on record, although less severe than in metropolitan France (-7.9% for metropolitan France in 2020).

Sugar was traditionally the chief agricultural product and export. Tourism is now an important source of income. The island's remote location combined with its stable political alignment with Europe makes it a key location for satellite receiving stations and naval navigation.

GDP sector composition in 2017 (contribution of each sector to the total gross value added):

Unemployment is a major problem on Réunion, although the situation has improved markedly since the beginning of the 2000s: the unemployment rate, which stood above 30% from the early 1980s to the early 2000s, declined to 24.6% in 2007, then rebounded to 30.0% in 2011 due to the 2008 financial crisis and subsequent Great Recession, but declined again after 2011, reaching 19.0% in 2023, its lowest level in 45 years.

In 2021, 36.1% of the population lived below the poverty line (defined by INSEE as 60% of Metropolitan France's median income; in 2021 the poverty line for a family of two parents and two young children was €2,423 (US$2,868) per month), a marked decrease compared to 2013 when 49% of the population lived below the poverty line.

The tertiary sector, particularly the commercial sector, is by far the most developed, and import distribution has taken off in the mid-1980s through affiliation and franchising agreements with metropolitan groups. The advent of franchised distribution has transformed the commercial apparatus, which historically was characterized by the geographic dispersion of small grocery-type units; the few "Chinese stores" still in operation are limited to mid-range towns and, as relics of a bygone era, have more of a tourist and educational appeal, even if they retain a convenience store function.

Rum distillation contributes to the island's economy. A "Product of France", it is shipped to Europe for bottling, then shipped to consumers around the world.

Brasseries de Bourbon is the main brewery of the island, with Heineken as shareholder.

Tourism

Income from tourism is Réunion's primary economic resource, ahead of sugarcane production and processing, which has allowed the development of large Réunionese groups such as Quartier Français, Groupe Bourbon ex-Sucreries Bourbon, a large international company now listed on the stock exchange, but based outside the island and which has abandoned the sugar sector for the off-shore maritime sector. With the reduction of subsidies, this culture is threatened. Therefore, the development of fishing in the French Southern Territories has been promoted.

Among the island's museums, the Musée de Villèle—located on a former colonial plantation—addresses the subject of slavery.

Agriculture

Agriculture in Réunion is an important activity in the island's economy: the agricultural territory covering 20% of the island's surface area employs 10% of the active population, generates 5% of the gross regional product, and provides the island's main export. Formerly centred on coffee and clove cultivation, it has focused on sugar cane since the events of the early 19th century, namely the Great Avalanches and the seizure of Réunion by the British. Today it faces important issues related to the decisions of the World Trade Organization at the international level and the development of the urban fact at the local level.

Réunion Island has about 7,000 farms, 5,000 of which are professional. These farms mobilize almost 11,000 AWU (annual workload of one person on a full-time basis).

Ninety-seven percent of the farms in Réunion are less than 20 hectares in size, compared to an average of 78 hectares in mainland France.

The most common status is that of an individual farmer (97%).

In 2005, more than 60% of farm managers were between 40 and 59 years old.

Public services

Health

In 2005–2006, Réunion experienced an epidemic of chikungunya, a viral disease similar to dengue fever brought in from East Africa, which infected almost a third of the population because of its transmission through mosquitoes. The epidemic has since been eradicated. See § History for more details.

Transportation

Roland Garros Airport serves the island, handling flights to mainland France, Madagascar, Mauritius, Tanzania, Comoros, Seychelles, South Africa, China, and Thailand. Pierrefonds Airport, a smaller airport, has some flights to Mauritius and Madagascar. In 2019, a light rail system was proposed to link Le Barachois with the airport.

Education

Réunion Island has its own education system. Chantal Manès-Bonnisseau, Inspector General of Education, Sport and Research, was appointed Rector of the Académie de La Réunion and Chancellor of Universities at the Council of Ministers on 29 July 2020.

She succeeds Vêlayoudom Marimoutou, who took office as secretary general of the Indian Ocean Commission on 16 July.

The Rectorate is located in the main city, in the Moufia district of Saint-Denis. At the start of the 2012 school year, the island had 522 pre-school or primary schools, including 26 private schools, for 120,230 students at the primary level, 82 secondary schools, including six private schools, for 61,300 students, 32 general and technological high schools, including three private schools, for 23,650 students, and 15 vocational schools, including two private schools, for 16,200 students.

Réunion's priority education zones affect slightly more than half of the primary and secondary school students.

Baccalaureate results are relatively close to the national average, with a rate of 81.4% in 2012 compared to 82.4% in 2011 (respectively: 84.5% and 85.6% in the national average).

In higher education, the University of Réunion has 11,600 students spread across the various sites, especially in Saint-Denis and Le Tampon. A further 5,800 students are divided between the post-baccalaureate courses of secondary education and other higher studies.

Energy

Energy on Réunion depends on oil and is limited by the island's insularity, which forces it to produce electricity locally and import fossil fuels. Faced with increasing demand and environmental requirements, the energy produced on the island is tending to increasingly exploiting its great renewable energy potential through the development of wind farms, solar farms, and other experimental projects. Although 35% of Réunion's electricity came from renewable sources in 2013, the department's energy dependency rate exceeded 85%. Saving electricity and optimising energy efficiency are two major areas of work for the authorities responsible for energy issues.

Hydroelectric power

Due to the large volumes of rainfall, the flow of surface water allows the installation of hydroelectric infrastructures, especially as erosion has carved out narrow and very deep ravines. The Sainte-Rose plant (22 MW) and the Takamaka plant (17.5 MW) are the two largest. In total, the island's six hydroelectric infrastructures have a capacity of 133 MW.

Symbols

Réunion has no official coat of arms or flag.

Former Governor Merwart created a coat of arms for the island on the occasion of the 1925 colonial exhibition organised on Petite-Île. Merwart, a member of the Réunion Island Society of Sciences and Arts, wanted to include the island's history:

• the bees evoke the Empire;
• the central coat of arms evokes the French Republican flag;
• the fleurs-de-lis evoke the royal era;
• The motto "Florebo quocumque ferar" is that of the French East India Company and means "I will bloom wherever they take me", while the vanilla vines honour a flourishing harvest.
• The Roman numeral "MMM" evokes the altitude of the highest peaks;
• The ship Saint-Alexis is the one that first took possession of the island;

The most commonly used flag in Réunion is that of the "radiant volcano", designed by Guy Pignolet in 1975, sometimes called "Lo Mavéli": it represents the volcano of Piton de la Fournaise in the form of a simplified red triangle on a navy blue background, while five sunbeams symbolise the arrival of the populations that have converged on the island over the centuries.
