Peter III (21 February 1728 – ) was emperor of Russia for six months in 1762. He was born in Kiel as Karl Peter Ulrich, the only child of Charles Frederick, Duke of Holstein-Gottorp and Anna Petrovna, the elder surviving daughter of Peter the Great. The German Peter could hardly speak Russian and pursued a strongly pro-Prussian policy, which made him an unpopular leader. He was deposed and possibly assassinated as a result of a conspiracy led by his German wife Princess Sophie Friederike Auguste von Anhalt-Zerbst-Dornburg, who succeeded him to the throne as Catherine II. His death could also have been the result of a drunken brawl with his bodyguard when he was being held captive after Catherine's coup.
