Peter III was the Emperor of Russia for a brief period in 1762. He was born in 1728 and was the grandson of Peter the Great, a significant figure in Russian history. Peter III is often remembered for his controversial policies, including his admiration for Frederick the Great of Prussia, which led to discontent among the Russian nobility and military. His reign lasted only six months before he was overthrown in a coup led by his wife, Catherine the Great. After his abdication, Peter III was imprisoned and later died under mysterious circumstances. His short rule marked the beginning of a new era in Russian history under Catherine's leadership.
