Night of the Long Knives
Adolf Hitler moved against the SA and its leader, Ernst Röhm, because he saw the independence of the SA and the penchant of its members for street violence as a direct threat to his power. Hitler also wanted to forestall any move by leaders of the Reichswehr, the German military, who both feared and despised the SA, to curtail his rule, especially since Röhm made no secret of his ambition to absorb the Reichswehr with himself at its head. Adolf Hitler also killed them because the were becoming difficult to control and he was worried that they would branch off and want independence to carry out more radical ideas.
