William (III) of Orange

King of Great Britain and Ireland from 1688, the son of William II of Orange and Mary, daughter of Charles I. He was offered the English crown by the parliamentary opposition to James II. He invaded England in 1688 and in 1689 became joint sovereign with his wife, Mary II, daughter of the deposed James II. He spent much of his reign campaigning, first in Ireland, where he defeated James II at the Battle of the Boyne in 1690, and later against the French in Flanders. He died childless and was succeeded by Mary's sister, Anne.
