History of Russia
The war ended in 1721 when an exhausted Sweden sued for peace with Russia. Peter acquired four provinces situated south and east of the Gulf of Finland, thus securing his coveted access to the sea. There, in 1703, he had already founded the city that was to become Russia's new capital, Saint Petersburg, as a "window opened upon Europe" to replace Moscow, long Russia's cultural center. Russian intervention in the Commonwealth marked, with the Silent Sejm, the beginning of a 200-year domination of that region by the Russian Empire. In celebration of his conquests, Peter assumed the title of emperor, and the Russian Tsardom officially became the Russian Empire in 1721.
Peter the Great
Peter the Great (), Peter I () or Peter Alexeyevich (;  – ) ruled the Tsardom of Russia and later the Russian Empire from 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.
