Quick Summary

Bizonia was a historical division of Germany formed in 1947 by the amalgamation of the American and British occupation zones. This union aimed to foster economic recovery by creating a unified administrative and economic entity, with German institutions located in Frankfurt am Main. Bizonia served as a model for the future West German state, establishing a federal structure and laying the groundwork for its economic policies, notably the promotion of a social market economy under Ludwig Erhard. The subsequent inclusion of the French zone in 1949 led to the formation of Trizonia, further paving the way for the establishment of the Federal Republic of Germany (West Germany) in May 1949.1
