Under Peter the Great, Russia was proclaimed an Empire in 1721, and became one of the European great powers. Ruling from 1682 to 1725, Peter defeated Sweden in the Great Northern War (1700−1721), forcing it to cede West Karelia and Ingria (two regions lost by Russia in the Time of Troubles), as well as the Governorate of Estonia and Livonia, securing Russia's access to the sea and sea trade. In 1703, on the Baltic Sea, Peter founded Saint Petersburg as Russia's new capital. Throughout his rule, sweeping reforms were made, which brought significant Western European cultural influences to Russia.
