6 July] 1762) (Russian: ???? III ?ë???????, Pyotr III Fyodorovich) was Emperor of Russia for six months in 1762.
He was born in Kiel as Charles Peter Ulrich of Schleswig-Holstein-Gottorp (German: Karl Peter Ulrich von Schleswig-Holstein-Gottorf), the only child of Charles Frederick, Duke of Holstein-Gottorp (the son of Hedvig Sophia of Sweden, sister of Charles XII), 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 of Anhalt-Zerbst, who succeeded him to the throne as Catherine II.
However, another theory is he died as a result of a drunken brawl with his bodyguard while he was being held captive after Catherine's coup.Despite his generally poor reputation, Peter made some progressive reforms during his short reign.
He proclaimed religious freedom (a very enlightened move for the time) and encouraged education.
He sought to modernize the Russian army.
He abolished the secret police, which had been infamous for its extreme violence, and made it illegal for landowners to kill their serfs without going to court.
Catherine adopted some of his reforms and reverted others.
