Through Germany, Holy Roman Empire and World War I

Originally a small settlement, Kiel was granted city rights in 1242. Over the centuries, it developed as an important port and trading hub, particularly due to its strategic location on the Kieler Förde inlet. Kiel became part of the Duchy of Holstein, the northernmost state of the Holy Roman Empire. From 1773 to 1864, it was ruled in personal union by the king of Denmark. In 1864, after the Second Schleswig War, the city was incorporated into the Kingdom of Prussia. During the 20th century, Kiel played a significant role in both World War I and World War II, with its naval significance and shipbuilding industry. Following World War II, it became part of West Germany and later reunified Germany.

Kiel is one of Germany's major maritime centres, known for a variety of international sailing events, including the annual Kiel Week, which is the biggest sailing event in the world. Kiel is also known for the Kiel Mutiny, when sailors refused orders to prepare to engage the British Navy in the last weeks of World War I, sparking the German Revolution, which led to the abdication of the Kaiser and the formation of the Weimar Republic. The Olympic sailing competitions at the 1936 and 1972 Summer Olympics were held in the Bay of Kiel.

Kiel has also been one of the traditional homes of the German Navy's Baltic fleet, and continues to be a major high-tech shipbuilding centre. Kiel University, founded in 1665, is home to the GEOMAR – Helmholtz Centre for Ocean Research Kiel. Kiel is an important sea transport hub, with passenger ferries to Sweden, Norway, Lithuania and other countries. Moreover, today the Port of Kiel is a popular destination for cruise ships touring the Baltic Sea.

History

Middle Ages

The city of Kiel was founded in 1233 as Holstenstadt tom Kyle by Count Adolf IV of Holstein, and granted Lübeck city rights in 1242 by Adolf's eldest son, John I of Schauenburg. As a part of Holstein, Kiel belonged to the Holy Roman Empire and was situated only a few kilometres south of the Danish border.

The capital of the county (later duchy) of Holstein, Kiel was a member of the Hanseatic League from 1284 until it was expelled in 1518 for harbouring pirates. The Kieler Umschlag (trade fair), first held in 1431, became the central market for goods and money in the Duchy of Holstein. It began to decline c. 1850 and ceased in 1900.

Modern times

Kiel University was founded on 29 September 1665 by Christian Albert, Duke of Holstein-Gottorp. A number of important scholars, including Theodor Mommsen, Felix Jacoby, Hans Geiger and Max Planck, studied or taught there.

From 1773 to 1864, the town belonged to the king of Denmark. However, because the king ruled Holstein as a fief of the Holy Roman Empire only through a personal union, the town was not incorporated as part of Denmark proper. Even though the empire was abolished in 1806, the Danish king continued to rule Kiel only through his position as Duke of Holstein, which became a member of the German Confederation in 1815. When Schleswig and Holstein rebelled against Denmark in 1848 (the First Schleswig War), Kiel became the capital of Schleswig-Holstein until the Danish victory in 1850.

During the Second Schleswig War in 1864, Kiel and the rest of the duchies of Schleswig and Holstein were conquered by a German Confederation alliance of the Austrian Empire and the Kingdom of Prussia. After the war, Kiel was briefly administered by both the Austrians and the Prussians, but the Austro-Prussian War in 1866 led to the formation of the Province of Schleswig-Holstein and the annexation of Kiel by Prussia in 1867. On 24 March 1865, King William I based Prussia's Baltic Sea fleet in Kiel instead of Danzig (Gdańsk). The Imperial shipyard Kiel was established in 1867 in the town.

When William I of Prussia became Emperor William I of the German Empire in 1871, he designated Kiel and Wilhelmshaven as Reichskriegshäfen ("Imperial War Harbours"). The Kiel Yacht Club was established in 1887 with Prince Henry of Prussia as its patron. Emperor Wilhelm II became its commodore in 1891.

Because of its new role as Germany's main naval base, Kiel very quickly increased in size in the following years, from 18,770 in 1864 to about 200,000 in 1910. Much of the old town centre and other surroundings were levelled and redeveloped to provide for the growing city. The Kiel tramway network, opened in 1881, had been enlarged to 10 lines, with a total route length of 40 km (25 mi), before the end of the First World War.

Kiel was the site of the sailors' mutiny which led to the German Revolution in late 1918. Just before the end of the First World War, the German fleet stationed at Kiel was ordered to sail out for a last great battle with the Royal Navy. The sailors, who thought of it as a suicide mission which would have no effect on the outcome of the war, decided they had nothing to lose and refused to obey orders. They took over Kiel and then spread out to other north German ports, sparking the revolution which led to the abolition of the monarchy and the creation of the Weimar Republic.

During the Second World War, Kiel remained one of the major naval bases and shipbuilding centres of the German Reich. There was also a labour camp for the local industry. Owing to its status as a naval port and production site for submarines, Kiel was heavily bombed by the Allies during this period. The bombing destroyed more than 80% of the remaining old town, 72% of the central residential areas, and 83% of the industrial areas. During the RAF bombing of 23/24 July 1944, Luftwaffe fighters tried to intercept the spoof (i.e. decoy) force instead of the main force attacking Kiel, and there was no water for three days; trains and buses did not run for eight days and there was no gas available for cooking for three weeks.

There were several bombing raids of the port area during the period 20 February – 20 April 1945 which successfully eliminated many U-boats, and the few large warships (cruisers Hipper, Scheer, and Köln) still afloat at that time. It and its port, and the canal were seized by a British T-Force led by Major Tony Hibbert on 5 May 1945.

Like other heavily bombed German cities, the city was rebuilt after the war. In 1946, Kiel was named the seat of government for Schleswig-Holstein, and it officially became the state's capital in 1952.

Today, Kiel is once again an important maritime centre of Germany, with high-tech shipbuilding, submarine construction and one of the world's largest ocean research centers, the GEOMAR. In 2006, Kiel was one of the founding cities of the original European Green Capital Award.
