The Aufbau Vereinigung (Reconstruction Organisation) was a Munich-based counterrevolutionary conspiratorial group formed in the aftermath of the German occupation of the Ukraine in 1918 and of the Latvian Intervention of 1919. It brought together White Russian émigrés and early German National Socialists who aimed to overthrow the governments of Germany and the Soviet Union, replacing them with authoritarian régimes of the far right. The group was originally known as Die Bruecke (The Bridge). Aufbau was also the name of a periodical it brought out.[1]

According to Michael Kellogg,[2] the Aufbau Vereinigung was a vital influence on the development of Nazi ideology in the years before the Beer Hall Putsch of 1923 as well as financing NSDAP with, for example, funds from Henry Ford. It gave Hitler the idea of a vast Jewish conspiracy, involving a close alliance between international finance and Bolshevism and threatening disaster for mankind.[3] Recent research on Hitler's early years in Vienna (1905-1913) appears to have shown that his antisemitism was at that time far less developed than it became under the new influences.[4]
