Queen Mary II (1662-1694) was queen of England, Scotland, and Ireland from 1689 until her death in 1694. She ruled jointly with her husband, William III. They were both Protestant, and overthrew her father, Roman Catholic James II, in the bloodless Glorious Revolution of 1688.
In actuality, Mary only ruled during her husband's absences. She was a fairly popular monarch in the Netherlands and England, but was troubled by the intense political disputes between her and her father and her sister Anne. She kept her primary allegiance to her husband; she believed that this was her religious duty. Although her father and mother both converted to Roman Catholicism, Mary was raised Protestant.
