The Oster Conspiracy hoped to reinstate the grandson of which British Monarch as Emperor?
Oster Conspiracy The Oster Conspiracy of 1938 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 Generalmajor (major general) Hans Oster, deputy head of the "Abwehr" and other high-ranking conservatives within the Wehrmacht who opposed the regime for its behaviour that was threatening to bring Germany into a war that they believed it was not ready to fight. They planned to overthrow Hitler and the Nazi regime through a planned storming of the Reich Chancellery by forces loyal to the plot to take control of the government, who would either arrest or assassinate Hitler, and restore the exiled Wilhelm II as Emperor.
