Through Sovereignty, United Kingdom and De facto and de jure

While Argentina claims a right to colonise the territory for economic gain, Britain has supported the right of self-determination of Falkland islanders. Today, Falkland Islanders overwhelmingly prefer to remain British. Following the British victory in the Falklands War, they were granted full British citizenship under the British Nationality (Falkland Islands) Act 1983. Argentina rejects the case for self-determination, as it views the islanders as "transplanted people" brought in by the British, ignoring the portion of the population with Argentinian origins and that there was no native people to begin with. Instead, Argentina argues that they do not have UN-recognised rights to self-determination, and instead argues for territorial integrity. Several South American countries and organizations support the Argentinian position, while the European Union recognizes the British administration. Most other countries do not take sides in the sovereignty dispute over the islands.

Historical basis of the dispute

Pre-settlement claims

In 1493, Pope Alexander VI issued a Papal bull, Inter caetera, dividing the New World between Spain and Portugal. The following year, the Treaty of Tordesillas between those countries agreed that the dividing line between the two should be 370 leagues west of the Cape Verde Islands. The Falklands lie on the western (Spanish) side of this line.

There is some limited evidence resulting in speculation of a possible human presence on the islands predating European arrival. The British were the first to land on the Falklands, and did so in 1690, when Captain John Strong sailed through Falkland Sound, naming this passage of water after Anthony Cary, 5th Viscount of Falkland, the First Lord of the Admiralty at that time. The British were keen to settle the islands as they had the potential to be a strategic naval base for passage around Cape Horn.


Spain made claims that the Falkland Islands were held under provisions in the 1713 Treaty of Utrecht, which defined the limits of the Spanish Empire in the Americas. However, the treaty only promised to restore the territories in the Americas held prior to the War of the Spanish Succession. The Falkland Islands were not held at the time, nor were they mentioned in the treaty.

Early settlements

France was the first country to establish a permanent settlement in the Falkland Islands, with the foundation of Port-Saint-Louis on East Falkland by French explorer Louis Antoine de Bougainville in 1764. Back in France, King Louis XV formally ratified possession of the islands on 12 September 1764. The French colony consisted of a small fort and some settlements with a population of around 250. The islands were named after the Breton port of Saint-Malo as the Îles Malouines, which remains the French name for the islands.

In 1765, Captain John Byron landed on Saunders Island. He then explored the coasts of the other islands and claimed the archipelago for Britain. The following year, Captain John MacBride returned to Saunders Island and constructed a fort named Port Egmont.

First sovereignty disputes

When Spain discovered the British and French colonies on the Islands, a diplomatic row broke out among the three claimants. In 1766, Spain and France, who were allies at the time, agreed that France would hand over Port Saint Louis, and Spain would reimburse de Bougainville and the Saint-Malo Company 618,108 French livres for the cost of the settlement. France insisted that Spain maintain the colony in Port-Louis to prevent Britain from claiming unilateral title to the Islands, and Spain agreed. Spain and Great Britain enjoyed uneasy relations at the time, and no corresponding agreement was reached.

The Spanish took control of Port Saint Louis and renamed it Puerto Soledad in 1767. On 10 June 1770, a Spanish expedition was sent to the British colony at Port Egmont. Facing a greater force, the British were expelled from Port Egmont, and Spain took de facto control of the Islands. The British threatened war over the issue, but both sides concluded a treaty on 22 January 1771, allowing the British to return to Port Egmont with neither side relinquishing sovereignty claims.

British and Spanish withdrawal

However, in 1774, economic pressures leading up to the American Revolutionary War forced Great Britain to withdraw from the Falklands along with many of its other overseas settlements. They left behind a plaque and flag at Port Egmont asserting British sovereignty over the islands. This left Spain in de facto control, with the British maintaining they had the rights to return at any time. In 1777, Governor Ramon de Carassa was ordered to destroy the remains at Port Egmont. The British plaque was removed and sent to Buenos Aires. Spain ruled the islands from 1774 until 1811 from Port Soledad as part of the Viceroyalty of the Río de la Plata. In this period, 18 Spanish governors were appointed to rule the islands. Spanish troops remained until 1811, when Governor Pablo Guillen Martinez was called back to Montevideo as the revolutionary forces spread through the continent. As the Spanish government withdrew, he left behind a plaque claiming sovereignty for Spain.

This left no formal government present on the islands. Despite the lack of administration or governance, they retained human activity. British and American sealers routinely used them to hunt for seals, also taking on fresh water as well as feral cattle, pigs and even penguins for provisions. Whalers also used the islands to shelter from the South Atlantic weather and to take on fresh provisions.

Colonel Jewett's declaration

Argentina declared its independence from Spain in 1816, although this was not then recognised by any of the major powers. In 1823, Britain appointed Woodbine Parish as consul-general to Buenos Aires and concluded a friendly treaty with the government of the United Provinces of the Río de la Plata on 2 February 1825, but, like the US, did not recognise the full extent of the territory claimed by the new state.

In October 1820, the frigate Heroína, under the command of American privateer Colonel David Jewett, arrived in Puerto Soledad after an eight-month voyage and with most of her crew incapacitated by scurvy and other disease. A storm had severely damaged the Heroína and had sunk a Portuguese ship pirated by Jewett called the Carlota. The captain sought assistance from the British explorer James Weddell to put the ship into harbour. Weddell reported that only thirty seamen and forty soldiers out of a complement of 200 were fit for duty and that Jewett slept with pistols over his head following an attempted mutiny. On 6 November 1820, Jewett raised the flag of the United Provinces of the Río de la Plata (the nation that would become Argentina) and claimed possession of the islands for the new state. Weddell reported that the letter he received from Jewett read:

"Sir, I have the honour to inform you of the circumstance of my arrival at this port, commissioned by the supreme government of the United Provinces of South America to take possession of these islands in the name of the country to which they naturally appertain."

Many modern authors report this letter as the declaration issued by Jewett. Jewett's report to the government of Buenos Aires does not mention any claim to the Falkland Islands, and news of the claim reached Argentina by way of the United States and Europe in November 1821, over a year after the event.

Before the Treaty was signed in 1825, Parish had requested from Argentine Foreign Minister Bernardino Rivadavia a general account of Buenos Aires and the provinces of the Río de la Plata for reference. Written by Rivadavia's secretary, Ignacio Núñez, the published report did not mention the Falkland Islands.

United Provinces governance

Subject to survey and demarcation of the property, the Government of Buenos Aires Province granted land on East Falkland to Jorge Pacheco in 1823, and fishing and hunting rights the following year. Pacheco was a businessman from Buenos Aires who owed money to the merchant Luis Vernet. A first expedition financed by Pacheco travelled to the islands the following year, arriving on the East Falkland on 2 February 1824. Its leader was Pablo Areguatí, who brought with him 25 gauchos. Ten days later Areguatí wrote to Pacheco to say the colony was perishing because the horses they had brought were too weak to be used. Thus, they could not capture wild cattle, and their only other means of subsistence was wild rabbits. On 7 June, Areguatí left the islands, taking with him 17 gauchos, with the remaining eight gauchos being rescued by the Susannah Anne, a British sealer, on 24 July. A second attempt, in 1826, sanctioned by the British (but delayed until winter by a Brazilian blockade), also failed after arrival in the islands.

After the failure, Pacheco agreed to sell his share to Vernet. The Buenos Aires government granted Vernet all of East Falkland, including all its resources, with exemption from taxation for 20 years, if a colony could be established within three years. Vernet visited the British consulate in 1826 seeking endorsement of his venture. The British acquiesced, and asked for a report on the islands. Vernet took settlers, including British Captain Matthew Brisbane, and before leaving once again sought permission from the British Consulate in Buenos Aires. He established a fledgling colony in 1828, and renamed Puerto Soledad to Puerto Luis. Vernet would visit the British consulate a third time in 1829, seeking continued endorsement of his venture and British protection for his settlement in the event of their returning to the islands. After receiving assurances from the British minister chargé d'affaires, Sir Woodbine Parish, Vernet provided regular reports to the British on the progress of his enterprise. He expressed the wish that, in the event of the British returning to the islands, the British Government would take his settlement under their protection; Parish duly passed this wish on to London. Islanders were born during this period, including Malvina María Vernet y Saez, Vernet's daughter.

The land grant on the islands later became the subject of compensation petition. In 1879, the heirs of Vernet requested an indemnity for the losses sustained on the islands. This petition was rejected by the Argentine Senate in 1882, following the approval of the Home Affairs Committee’s opinion, which claimed that Vernet’s land had been granted without right by the Government of Buenos Aires.

In 1829, he sought a naval vessel from the United Provinces to protect his colony. As none were available, the Buenos Aires government, headed by General Juan Galo de Lavalle, appointed him Military and Civil Commander, essentially the governor of the islands. This prompted British protests, as this was seen as an attempt by the United Provinces to exercise political and military control over the islands. Parish protested to Buenos Aires, which merely acknowledged the protest. Britain protested again when Vernet announced his intention to exercise exclusive rights over fishing and sealing in the islands. One of Vernet's first acts was to curb seal hunting on the islands to conserve the dwindling seal population. In response, the British consul at Buenos Aires protested the move and restated the claim of his government. Similar protests were received from the American representative, who protested at the curtailment of established rights and stated that the United States did not recognise the jurisdiction of the United Provinces over the islands. Despite the tension, Vernet continued to provide regular reports to Parish throughout this period.

Lexington raid and escalating chaos

Vernet's actions

Vernet's attempts to regulate fishing and sealing led to conflict with the United States and the Lexington raid of 1831. Vernet seized three American ships, the Harriet, Superior and Breakwater, for disobeying his restrictions on seal hunting. The Breakwater escaped to raise the alarm and the Superior was allowed to continue its work for Vernet's benefit, but property on board the Harriet was seized and Vernet returned with it to Buenos Aires for the captain to stand trial. The American Consul in Argentina protested Vernet's actions and stated that the United States did not recognise Argentine sovereignty in the Falklands. The consul dispatched a warship, the USS Lexington, to Puerto Luis to retake the confiscated property.

Although the colony was successful enough to be advertising for new colonists at this time, a report by the captain of the Lexington suggests that the conditions on the islands were quite miserable as a result of the Harriet seizure and Lexington raid. The captain of the Lexington asserted in his report that he destroyed the settlement's powder store and spiked the guns, though Vernet later claimed that during the raid the Argentine settlement at Puerto Luis was also destroyed. Upon leaving to return to Montevideo, the captain of the Lexington declared the islands to be res nullius (nobody's property). Darwin's visit in 1833 confirmed the squalid conditions in the settlement, although Captain Matthew Brisbane, Vernet's deputy, later insisted that these were the result of the attack by the Lexington. Vernet had returned to Buenos Aires in 1831 before the attack and resigned as governor.

With the colony in disarray, Major Esteban Mestivier was appointed interim governor and tasked by the United Provinces with the establishment of a penal colony. He arrived at Puerto Luis with his family aboard the schooner Sarandí in October 1832. The Sarandí, under the command of its captain, José María Pinedo, then began to patrol the surrounding seas. Upon its return to Puerto Luis on 29 December 1832, the Sarandí found the colony in an uproar. In Pinedo's absence, there had been a mutiny led by a man named Gomila; Mestivier had been murdered and his wife raped. The captain of the French vessel Jean Jacques had meanwhile provided assistance, disarming and incarcerating the mutineers. Pinedo dispatched the mutineers to Buenos Aires with the British schooner Rapid. Gomila was condemned to exile, while seven other mutineers were executed.

American position

The American sealing vessels Harriet and Breakwater that had been seized by Vernet brought claims against their insurers and in 1839 these claims reached the Supreme Court of the United States in the case of Williams v. Suffolk Insurance Company. The insurers argued that Vernet was the legal governor of the Falkland Islands, the sealing was therefore illegal and so they ought not to have to pay. The ruling of the Supreme Court was:

The government of the United States having insisted, and continuing to insist, through its regular executive authority, that the Falkland Islands do not constitute any part of the dominions within the sovereignty of Buenos Ayres, and that the seal fishery at those islands is a trade free and lawful to the citizens of the United States, and beyond the competence of the Buenos Ayres government to regulate, prohibit, or punish, it is not competent for a circuit court of the United States to inquire into and ascertain by other evidence the title of the government of Buenos Ayres to the sovereignty of the Falkland Islands.

As the United States recognized the British and not the Argentine claim to the islands, the insurers had to pay.

British response

Mestivier's appointment again had drawn protests from the British consul in Buenos Aires, but these protests received no response from Buenos Aires, as the United Provinces were now asserting sovereignty over the islands. The appointments of Vernet and Mestivier convinced the British that direct rule was again necessary, and so the British dispatched a naval squadron to re-establish direct British rule.

British return and establishment of control

The British squadron to restore sovereignty arrived at Port Egmont on 20 December 1832, and reached Port Louis on 2 January 1833.

Captain James Onslow, of the brig-sloop HMS Clio, arrived at the Spanish settlement at Port Louis to request that the Argentine flag be replaced with the British one, and that the Argentine administration leave the islands. Pinedo asked if war had been declared between Argentina and the United Kingdom; Onslow replied that it had not. While Pinedo wanted to resist, his numerical disadvantage was obvious, particularly as a large number of his crew were British mercenaries who were unwilling to fight their own countrymen. Such a situation was not unusual in the newly independent states in Latin America, where land forces were strong, but navies were frequently quite undermanned. He protested verbally, but departed without a fight on 5 January under protest, with the Argentine flag being lowered by British officers and delivered to him. The islands have remained under British rule ever since, except for the brief interruption caused by the Falklands War. Back on the mainland, Pinedo faced court martial; he was suspended for four months and transferred to the army, though he was recalled to the navy in 1845.

After their return, the British did not attempt to develop the islands as a colony. Initially, plans were based upon the settlers remaining in Puerto Luis, supported by the annual visit of a warship. Vernet's deputy, Matthew Brisbane, returned in March 1833 aboard the sealer Rapid during the visit of HMS Beagle. He took charge of the settlement and was encouraged to further Vernet's business interests provided he did not seek to assert Argentine government authority. Argentines have claimed that the population of Puerto Luis was expelled after the British return, but historical records shows that only four members of the settlement chose to leave.

Following the Gaucho murders in August 1833, the Falklands were administered as a military outpost with the few remaining residents of Vernet's colony. The first British Resident, Lt Smith, was established in 1834. Under his administration and initiative, the settlement recovered and began to prosper. Lt Smith's commanding officer was not enthusiastic about Royal Navy officers engaged in encouraging commerce and rebuked Smith. Smith resigned and subsequent residents allowed the settlement to stagnate.

In Britain, the Reform Act 1832 had extended the vote to more British citizens, including members of the free-trade merchant class who saw economic opportunity in opening up markets in South America. The British Board of Trade saw establishing new colonies and trade with them as a way to expand manufacturing jobs. The Foreign and Colonial Offices agreed to take on the Falklands as one of these colonies, if only to prevent colonisation by others. In May 1840, a permanent colony was established in the Falklands. A British colonial administration was formed in 1842.

This was expanded in 1908, when in addition to South Georgia, claimed in 1775, and the South Shetland Islands, claimed in 1820, the UK unilaterally declared sovereignty over more Antarctic territory south of the Falklands, including the South Sandwich Islands, the South Orkney Islands and Graham Land, grouping them into the Falkland Islands Dependencies. Following the introduction of the Antarctic Treaty System in 1959, the Falkland Islands Dependencies were reduced to include just South Georgia and the South Sandwich Islands. Territory south of the 60th parallel was formed into a new dependency, the British Antarctic Territory, which overlaps claims by Argentina (Argentine Antarctica) and Chile (Antártica Chilena Province).
