William III. Of England, born in 1650. Having married Mary, daughter of James II, was regarded as a Protestant reserve against the latter and, in 1688, was called in to replace him. He defeated James at the Boyne in 1690, obtained the acknowledgement of his title from Louis XIV by the Peace of Ryswick (1697), but had prepared a grand alliance to renew the war with him just before he died, Louis having favored the claim of James Edward. Died 1702.
