The Federal Republic of Germany is a federation and consists of sixteen partly sovereign states (German: Länder, sing. Land). Of the 16 states, 13 are so-called "area-states" (Flächenländer); in these, below the level of the state government, there is a division into local authorities (counties and county-level cities) that have their own administration. Two states, Berlin and Hamburg, are city-states, in which there is no separation between state government and local administration. The state of Bremen is a special case: the state consists of the cities of Bremen, for which the state government also serves as the municipal administration, and Bremerhaven, which has its own local administration separate from the state government. It is therefore a mixture of a city-state and an area-state.Three states, Bavaria, Saxony, and Thuringia, use the appellation Freistaat ("free state"); this title is merely stylistic and carries no legal or political significance (similar to the US states that call themselves a commonwealth).
The Federal Republic of Germany ("West Germany") was created in 1949 through the unification of the three western zones previously under American, British, and French administration in the aftermath of World War II. Initially, the states of the Federal Republic were Baden (until 1952), Bavaria (Bayern), Bremen, Hamburg, Hesse (Hessen), Lower Saxony (Niedersachsen), North Rhine-Westphalia (Nordrhein-Westfalen), Rhineland-Palatinate (Rheinland-Pfalz), Schleswig-Holstein, Württemberg-Baden (until 1952), and Württemberg-Hohenzollern (until 1952). West Berlin, while still under occupation by the Western Allies, viewed itself as part of the Federal Republic and was largely integrated and considered a de facto state. In 1952, following a referendum, Baden, Württemberg-Baden, and Württemberg-Hohenzollern merged into Baden-Württemberg. In 1957, the Saar Protectorate joined the Federal Republic as the state of Saarland.
