Great Northern War
The Great Northern War (1700–21) was a conflict in which a coalition led by the Tsardom of Russia successfully contested the supremacy of the Swedish Empire in Central, Northern, and Eastern Europe. Brunswick-Lüneburg (Hanover) joined the coalition in 1714 for Hanover and in 1717 for Britain, and Brandenburg-Prussia joined it in 1715. The war ended with Sweden's defeat, leaving Russia as the new dominant power in the Baltic region and as a new major force in European politics. The Western powers, Great Britain and France, became caught up in the separate War of the Spanish Succession (1702-1715), which broke out over the Bourbon Philip of Anjou's succession to the Spanish throne and a possible joining of France to Spain.
