The palace coupe of the 1762
One of the most peaceful and
bloodless palace revolutions in history was the deposition of Peter III, son of Elizaveta Petrovna, a pro-Prussian and a very unpopular Emperor who only stayed on the throne for 6 months. He was overthrown by his own wife, then Empress-to-be Catherine the Great; she justified her act by claiming Peter was guilty of not respecting the Russian relics.
Peter's crucial mistake was still adhering to the Prussian order, especially in the military, while Russia was basically at war with the country, the fact of which greatly annoyed the army in particular. The army's support was the major reason for Catherine's success in the coup. When Peter III found out his throne was taken, he attempted to talk to Catherine but was met by the army. He had nothing left to do but to sign his resignation from the throne and leave.
