# Kiel

Kiel (/kiːl/ KEEL, German: ) is the capital and most populous city in the northern German state of Schleswig-Holstein. With a population of around 250,000, it is Germany's largest city on the Baltic Sea. It is located on the Kieler Förde inlet of the Bay of Kiel and lies in the southeast of the Jutland Peninsula, on the mouth of the Schwentine River, approximately 90 kilometres (56 mi) northeast of Hamburg. The world's busiest artificial waterway, the Kiel Canal, has a terminus in Kiel's Holtenau district. This canal connects the Baltic to the North Sea, with its other end in Brunsbüttel. Most of Kiel is part of Holstein. The boroughs north of the Schwentine also belong to Wagria, while those north of the Kiel Canal are historically part of Southern Schleswig.
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 of the 1936 and the 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. The University of Kiel, 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.
Kiel's recorded history began in the 13th century. Before then, in the eighth century, it was a Danish village. Until 1864 it was administered by Denmark in personal union. In 1866 the city was annexed by Prussia and in 1871 it became part of Germany.
Kiel was one of the founding cities of the original European Green Capital Award in 2006. In 2005 Kiel's GDP per capita was €35,618, which is well above Germany's national average, and 159% of the European Union's average.

## 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

The University of Kiel 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 slave 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. Regular ferries to Scandinavia and Lithuania, as well as the largest sailing event in the world called the Kiel Week (Kieler Woche) in German and The Kiel Regatta in English. The Kieler Umschlag is another festival, which has been taking place again since 1975. Kiel is also home to a large service sector and a number of research institutions including the University of Kiel, which is the oldest, largest, and most prestigious university in the state.

### Note

* ↑ Temperature data for Kiel have been recorded since 1940. The weather station data used from 1 January 1940 to 15 October 1988 came from Kiel-Kronshagen, and temperature data from 1 January 1974 to the present are from Kiel-Holtenau.

### Districts

Kiel has about 40 districts, but there is no standard division. The districts are traditionally grouped into 30 boroughs (Stadtteile). Another, more recent structure summarizes the districts in 18 political districts (Ortsteile). The city has 25 electoral districts.
The biggest districts, by population, are Wik (20,100), Gaarden-Ost (19,200) and Mettenhof (19,900). Gaarden, located at the southern end of the fjord, is a traditional working-class district that used to be home to mainly shipyard workers. Mettenhof is a large housing estate (satellite town) that was built in the 1960s and 1970s on the western outskirts of the city. The city districts of Düsternbrook, Schreventeich, Ravensberg and Blücherplatz, north of the city centre, are popular places to live with many 19th century buildings, villas and tree-lined streets. The government offices, ministries and parliament of the state of Schleswig-Holstein are also mainly based in these neighbourhoods, particularly Düsternbrook. In contrast to the heavy bomb damage inflicted on the central parts of the city during the Second World War, most of the residential areas were not severely damaged. Hence, Kiel's more modern-style inner city and Kiel's more historic/elaborate residential areas stand in architectural contrast to one another. There are plans for large-scale improvement and building efforts for the inner city, providing better pavements, better access to and view of the waterfront, and a generally more attractive feel to the place. These plans, most notably the "Kleiner Kiel Kanal", a restoration of a historic canal that was filled in to make place for road infrastructure, are to be implemented in the next few years.

### Main sights

The oldest building in the city is the 13th century Church of St. Nicholas, which has a sculpture by Ernst Barlach in front of it called Geistkämpfer.
Kiel is Schleswig-Holstein's largest city, and therefore Kiel's shopping district is a major attraction, and will see further improvement and renovation efforts in the upcoming years. Kiel's Holstenstraße (Holsten Street) is one of the longest shopping streets in Germany. The Rathaus (Town Hall), which was built in 1911, has an operating paternoster lift and the design of its tower was based on one in Venice. The square in front of it is bordered by a lake and the Opernhaus Kiel (Kiel Opera House). There are also a number of lakes and parks in the city centre, such as Schrevenpark. There are two botanical gardens, the Old Botanical Garden and the Botanischer Garten der Christian-Albrechts-Universität zu Kiel (or New Botanical Garden).
As Kiel is situated near the sea, the beaches to the north of Kiel, such as Strande, Kiel-Schilksee, Möltenort and Laboe, are also popular places to visit in spring and summer.
Kiel Week, also known in English as the Kiel Regatta, is the largest sailing event in the world and takes place every year in the last full week in June. Many thousands of boats and ships of all kinds and eras take part in the parade. Kiel Week is also a festival, Volksfest and fair as well as a maritime event. There are a number of yachting and sailing clubs in picturesque settings.
Kiel also features a number of museums, including zoological, geological, historical, fine art, industrial and military museums. Notable is the Stadt- und Schifffahrtsmuseum Warleberger Hof (City and Maritime Museum), which belongs to the association Museen am Meer. In addition to preserving architecture from the 16th century and historic rooms with painted stucco ceilings, it displays urban and cultural exhibits of the 19th and 20th centuries. Particularly intriguing is the history of the carnival in Kiel.
The Schifffahrtsmuseum is in the former fish market building in the harbour.
Laboe is home to the Laboe Naval Memorial and the Second World War submarine U-995, which are both popular tourist sites.

## Population

Kiel has a population of 247,000. In 1946, when Kiel became the capital of Schleswig-Holstein, its population was about 214,000. Kiel is Germany's largest coastal city and its only state capital located on the sea. In the 1950s Kiel, with its marine port, attracted members of the navy. Kiel had its highest peak of population in 1973 at 273,000. The population declined since then. Many people moved away from this city and Kiel became very poor and had a big problems with unemployed people at that time. Kiel is now a city with universities and active marine stations which attracts many young students and marines to Kiel.

Partly linked to the University Kiel are other independent research facilities such as the German National Library of Economics – Leibniz Informationcenter for Economy, the Kiel Institute for the World Economy, the GEOMAR Helmholtz Centre for Ocean Research Kiel and the research institute of the Bundeswehr for water sound and geophysics. Besides these there are other educational institutions such as the Fachhochschule Kiel (founded in 1969) and the Muthesius School of Arts (founded in 1907). The projects Murmann School of Global Management and Economics and Multimedia Campus Kiel were ultimately unsuccessful. The Wirtschaftsakademie Schleswig-Holstein offers besides advanced training at the Berufsakademie dual study courses for economists, business information specialists and industrial engineers.
