Augus'tus I, FREDERICK (Augustus II of Poland, 1670-1733), elector of Saxony and king of Poland. He succeeded his brother in the electorate in 1694, and when the Polish throne became vacant, by the death of John Sobieski, Augustus secured it. He joined with Peter the Great in the war against Charles XII of Sweden. In 1704 he was deposed, but after the defeat of Charles at Pultava, the Poles recalled him. The death of Charles XII put an end to the war, and Augustus concluded a peace with Sweden.
