Mary II (30 April 1662 – 28 December 1694) was Queen regnant of England, Scotland, and Ireland from 1689 until her death. Mary was a Protestant. She became queen after the Glorious Revolution, which resulted in the deposition of her Roman Catholic father, James II and VII. Mary ruled together with her husband, William III and II. He became the ruler of both countries when she died in 1694. Popular histories usually call their joint reigns as those of "William and Mary". Mary had less power than William when William remained in England. When William went to military campaigns, however, she governed alone. She was a powerful, firm, and effective ruler. She gave most of her authority to her husband, but he greatly depended on her. She was very active in the Church of England, ruling it as its Supreme Governor.
