Signing the Quadripartite Agreement on Berlin (June 3, 1972) Within the framework of the new policy of rapprochement, the Quadripartite Agreement on Berlin between the former Allies established the basis for the legal status of the divided city, for relations between West Berlin and the Federal Republic, and for access to West Berlin. This photograph shows the foreign ministers of the Allied Powers signing the final protocol of the agreement. With their signatures, the agreement, which had been negotiated back in September 1971, took effect.
