Peter III (February 21, 1728 – July 17 [O.S. July 6] ,1762) (Russian: Pyotr III Fyodorovich) is Emperor of Russia for six months in 1762.

He is very pro-Prussian, which makes him an unpopular leader.

He is supposedly assassinated as a result of a conspiracy led by his wife, who succeeds him to the throne as Catherine II.
