Night of the Long KnivesThe Night of the Long Knives (German: Nacht der langen Messer) or "Operation Hummingbird", or, more commonly used in Germany "Röhm-Putsch" 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 executions. Most of those killed were members of the Sturmabteilung, the paramilitary Brownshirts.
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. He also wanted to conciliate leaders of the Reichswehr, the official German military who both feared and despised the SAâin particular Röhm's ambition to absorb the Reichswehr into the SA under his own leadership. Finally, Hitler used the purge to attack or eliminate critics of his regime, especially those loyal to Vice-Chancellor Franz von Papen, and to settle scores with old enemies.
