At the Yalta Conference in 1945 , France was allocated an occupation zone for the administration of post-war Germany . The south-west of Germany – previously consisting of Baden , Württemberg and the Prussian province of Hohenzollern – was divided between France in the south and the United States in the north . The border between the two zones was set so that the Autobahn connecting Karlsruhe and Munich ( today the A8 ) was completely contained within the American zone ; Bavaria was also placed under American administration . In the French zone , Hohenzollern and the southern half of Württemberg were merged to form Württemberg-Hohenzollern . The southern half of Baden was established as South Baden on 1 December 1945 . Freiburg was designated as the capital of South Baden ; the former capital of Baden ( Karlsruhe ) was in the American zone
