This article is about the Russian monarch. For other uses, see Peter the Great (disambiguation). Peter the Great (Russian: Пётр Великий, tr. Pyotr Velikiy, IPA: [ˈpʲɵtr vʲɪˈlʲikʲɪj]), Peter I (Russian: Пётр I, tr. Pyotr I, IPA: [ˈpʲɵtr ˈpʲɛrvɨj]) or Peter Alexeyevich (Russian: Пётр Алексеевич, IPA: [ˈpʲɵtr ɐlʲɪˈksʲejɪvʲɪtɕ]; 9 June [O.S. 30 May] 1672 – 8 February [O.S. 28 January] 1725)[a] ruled the Tsardom of Russia and later the Russian Empire from 7 May [O.S. 27 April] 1682 until his death in 1725, 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 and also laid the groundwork for the Russian navy after capturing ports at Azov and the Baltic Sea. He led a cultural revolution that replaced some of the traditionalist and medieval social and political systems with ones that were modern, scientific, Westernised 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. He is also known for founding and developing the city of Saint Petersburg, which remained the capital of Russia until 1917.
