Erich Koch headed the East Prussian Nazi party from 1928. He led the district from 1932. This period was characterized by efforts to collectivize the local agriculture and ruthlessness in dealing with his critics inside and outside the Party. He also had long-term plans for mass-scale industrialization of the largely agricultural province. These actions made him unpopular among the local peasants. In 1932 the local paramilitary SA had already started to terrorise their political opponents. On the night of 31 July 1932 there was a bomb attack on the headquarters of the Social Democrats in Königsberg, the Otto-Braun-House. The Communist politician Gustav Sauf was killed; the executive editor of the Social Democrat "Königsberger Volkszeitung", Otto Wyrgatsch, and the German People's Party politician Max von Bahrfeldt were severely injured. Members of the Reichsbanner were attacked and the local Reichsbanner Chairman of Lötzen, Kurt Kotzan, was murdered on 6 August 1932.
