The Reichsvertretung der jüdischen Landesverbande was founded at the end of 1932 and it was superceded by the Reichsvertretung der Deutschen Juden as the first organisation to claim to be truly representative of all German Jews. Its principal achievement was the establishment of the Zentralausschuss für Hilfe und Aufbau (Central Committee for Aid and Reconstruction) which was to become the main social and economic instrument of German Jewry. The Preussische Landes Verband (The Prussian State League) was the largest regional Jewish organisation but had no legal standing.
