The Night of the Long Knives was a purge that took place in Nazi Germany between June 30 and July 2, 1934, when the Nazi regime carried out a series of political murders. Leading figures of the left-wing Strasserist faction of the Nazi Party, along with its figurehead, Gregor Strasser, were murdered, as were prominent conservative anti-Nazis (such as former Chancellor Kurt von Schleicher and Gustav Ritter von Kahr, who had suppressed Hitler's Beer Hall Putsch in 1923). Many of those killed were leaders of the Sturmabteilung (SA), the paramilitary brownshirts.
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 newly gained political power. Hitler also wanted to conciliate leaders of the Reichswehr, the official German military who feared and despised the SA—in particular Röhm's ambition to absorb the Reichswehr into the SA under Röhm's leadership. Additionally, Hitler was uncomfortable with Röhm's outspoken support for a "second revolution" to redistribute wealth. (In Röhm's view Hitler's election had accomplished the "nationalistic" revolution but had left unfulfilled the "socialistic" motive in National Socialism.) Finally, Hitler used the purge to attack or eliminate critics of his new regime, especially those loyal to Vice-Chancellor Franz von Papen, as well as to settle scores with old enemies.
