Peter the Great Peter the Great (Russian: Пётр Вели́кий , "Pyotr Velikiy"; ] ), Peter I (Russian: Пётр I , "Pyotr I"; ] ) or Peter Alexeyevich (Russian: Пётр Алексе́евич ; ] ; 9 June [O.S. 30 May] 1672  – 8 February [O.S. 28 January] 1725 ) ruled the Tsardom of Russia and later the Russian Empire from 7 May (O.S. 27 April) 1682 until his death, jointly ruling before 1696 with his elder half-brother, Ivan V. Through a number of successful wars he expanded the Tsardom into a much larger empire that became a major European power. He led a cultural revolution that replaced some of the traditionalist and medieval social and political systems with ones that were modern, scientific, westernized, and based on The Enlightenment. Peter's reforms made a lasting impact on Russia and many institutions of Russian government trace their origins to his reign.
