On this day in history:

Night of the Long Knives

From 30 June through 2 July 1934, under the orders of Adolf Hitler, Ernst Roehm, along with other leaders of the Nazi paramilitary organization, the Sturmabteilungen (SA), were purged, a task given to the SS. The Night of the Long Knives was also an opportunity for Nazi leaders to purge political enemies from the right.  The purge enabled the NSDAP to form an agreement with the German army, the Reichswehr, so that Hitler could declare himself Führer of Germany after President Hindenburg’s death, and attain absolute power.
