The Great Northern War was the war fought between a coalition of Denmark–Norway, Russia and Saxony-Poland (from 1715 also Prussia and Hanover) on one side and Sweden on the other side from 1700 to 1721. It started by a coordinated attack on Sweden by the coalition in 1700, and ended 1721 with the conclusion of the Treaty of Nystad, and the Stockholm treaties. As a result of the war, Russia supplanted Sweden as the dominant Power on the shores of the Baltic becoming a major player in European politics.
