The leadership of the Nazi Storm Troopers (SA), whose four million members had helped bring Hitler to power in the early 1930s, was especially targeted. Hitler feared that some of his followers had taken his early "National Socialism" propaganda too seriously and thus might compromise his plan to suppress workers' rights in exchange for German industry making the country war-ready.

In the early 1920s, the ranks of Hitler's Nazi Party swelled with resentful Germans who sympathized with the party's bitter hatred of Germany's democratic government, leftist politics, and Jews. In November 1923, after the German government resumed the payment of war reparations to Britain and France, the Nazis launched the "Beer Hall Putsch"—their first attempt at seizing the German government by force. Hitler hoped that his nationalist revolution in Bavaria would spread to the dissatisfied German army, which in turn would bring down the government in Berlin. However, the uprising was immediately suppressed, and Hitler was arrested and sentenced to five years in prison for high treason.
