At the end of June 1934, top officials of the SA and opponents of the regime, including Gregor Strasser, were arrested and killed in a purge later called the Night of Long Knives. Goebbels was present at the arrest of SA leader Ernst Röhm in Munich.
The demands of the SA for more political and military power caused anxiety among military, industrial, and political leaders. In response, Hitler purged the entire SA leadership in the Night of the Long Knives, which took place from 30 June to 2 July 1934. Hitler targeted Ernst Röhm and other SA leaders who, along with a number of Hitler's political adversaries, were rounded up, arrested, and shot.
