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.
Russian colonization of the Americas
The Russian colonization of the Americas covers the period from 1732 to 1867, when the Russian Empire laid claim to northern Pacific Coast territories in the Americas. Russian colonial possessions in the Americas are collectively known as Russian America. Russian expansion eastward began in 1552, and in 1639 Russian explorers reached the Pacific Ocean. In 1725, Emperor Peter the Great ordered navigator Vitus Bering to explore the North Pacific for potential colonization. The Russians were primarily interested in the abundance of fur-bearing mammals on Alaska's coast, as stocks had been depleted by over hunting in Siberia. Bering's first voyage was foiled by thick fog and ice, but in 1741 a second voyage by Bering and Aleksei Chirikov made sight of the North American mainland.
