Oster conspiracy
The Oster Conspiracy of 1938, also called the September Conspiracy (German: Septemberverschwörung), was a proposed plan to overthrow German Führer Adolf Hitler and the Nazi regime if Germany went to war with Czechoslovakia over the Sudetenland. It was led by Oberstleutnant Hans Oster, deputy head of the Abwehr, and high-ranking conservatives within the Wehrmacht who opposed the regime for behavior that was threatening to bring Germany into a war that they believed it was not ready to fight.
