Prince of Orange is a title of nobility, originally associated with the Principality of Orange, in what is now southern France.
It is carried by members of the House of Orange-Nassau, as heirs to the crown of the Netherlands, and is also seen carried by the pretenders by members of the House of Hohenzollern.
James II of England, who had come to the throne in 1685, was a Catholic, while most of the nation was Protestant. He was a poor politician and offended the leaders of the nation. When he married again and had a son in 1688, those leaders planned to remove him from the throne in favor of his older daughter, Mary, by a previous marriage. She had been raised by a Prostestant. She was married to her first cousin, William of Orange, stadtholder of the Netherlands, and also a Prostestant.
The plot was successful. James II was forced to flee and was succeeded by his nephew and his daughter, who ruled jointly as William III and Mary II. The changeover was virtually bloodless and was therefore called "the Glorious Revolution." It was accompanied by the acceptance by William and Mary of "the Declaration of Rights" on February 13, 1689. This made Parliament supreme in the nation.
