Great Northern War
Formation of a new anti-Swedish alliance

After Poltava, Peter the Great and Augustus the Strong allied again in the Treaty of Thorn (1709); Frederick IV of Denmark-Norway with Augustus the Strong in the Treaty of Dresden (1709); and Russia with Denmark–Norway in the subsequent Treaty of Copenhagen. In the Treaty of Hanover (1710), Hanover, whose elector was to become George I of Great Britain, allied with Russia. In 1713, Brandenburg-Prussia allied with Russia in the Treaty of Schwedt. George I of Great Britain and Hanover concluded three alliances in 1715: the Treaty of Berlin with Denmark–Norway, the Treaty of Stettin with Brandenburg-Prussia, and the Treaty of Greifswald with Russia.
