HIGHLIGHTS The modern German states were built after World War II during the allied occupation. The states in West Germany joined and formed the Federal Republic of Germany (Bundesrepublik Deutschland) in 1949. Only 7 of the 16 new states existed before: Bavaria, Bremen, Hamburg, Baden and Saarland in the west, Saxony and Thuringia in Eastern Germany. All other states were amalgamations of formerly much smaller states and Prussian provinces. In 1952 three south-western states (Baden, Württemberg-Hohenzollern and Württemberg-Baden) merged to form Baden-Württemberg. Five years later, France returned the Saarland to Germany. Berlin was not a state until the German reunification on 3rd October 1990. Berlin was under the sovereignty of the allies, USA, Great Britain, France and the Soviet-Union. There are 13 area states in Germany (Flächenländer), and 3 city states (Stadtstaaten), Berlin, Hamburg and Bremen. The latter actually consists of Bremen and Bremerhaven. Head of a state is the Ministerpräsident in the area states, and the Bürgermeister in the city states.
