Kiel

Kiel ( ; ) 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 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.

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 the unified Germany.
