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.
History of Russia (1721–96)
During the early nineteenth century, Russia's population, resources, international diplomacy, and military forces made it one of the most powerful states in the world. Its power enabled it to play an increasingly assertive role in Europe's affairs. This role drew the empire into a series of wars against Napoleon, which had far-reaching consequences for Russia and the rest of Europe.
