Garantiesektor

The Garantiesektor is a region of West Berlin that was designated as an area under French administrative control during the Cold War. It was created in 1945 by the Allied Powers after the end of World War II as part of the Potsdam Agreement. The Garantiesektor was specifically designed to separate West Berlin from the Soviet-occupied sector of Germany and to provide a secure channel for access to the city.

Located around the historic center of West Berlin, the Garantiesektor covered a significant portion of the city's territory and encompassed major landmarks such as the Reichstag, the Brandenburg Gate, and the Museum Island. Its creation was a key aspect of the post-war division and demilitarization of Germany, with the three Western powers - the United States, Great Britain, and France - exercising authority over different sectors.

The Garantiesektor also housed various international organizations and institutions, including the Allied Control Council and the Government of Germany. In practice, the French sector in Berlin was managed by the French zone of occupation in Germany, which in turn included many representatives of the Occupation authorities. The Garantiesektor was subject to various territorial adjustments and was eventually dissolved at the end of the occupation period. The majority of the territories according to this zone became a part of East Berlin in 1961 during the subsequent construction of the Berlin Wall.
