William was a prince of the House of Orange, the royal family of the Netherlands. He came to power in 1672 when he was appointed Captain-General and Stadholder and led the Dutch to victory over the French. In 1677 William married his cousin Mary, eldest daughter of the future James VII and II. In 1688 he accepted the invitation of seven Protestant peers to invade England and dislodge his Catholic father-in-law, now king. James fled to France and William was offered the throne jointly with Mary in 1689. This unsettling coloured wax image presents the king as a military hero; William spent much of his reign at war, first in Ireland and then against the French in Flanders.
