The Dutch king (technically, "Stadholder") was William of Orange, who was married to a member of English royal family. William's rule in the Netherlands was one in which he did not rule absolutely as a king. Rather, the nation there was more of a commonwealth with shared power. That's what the English Parliament members wanted. William and Mary, coming over from the Dutch Republic, would be willing to accept a Bill of Rights which would put restrictions on the king's power. The move to bring William over to become King William III of England became known as "The Glorious Revolution."
