William and Mary were the co-regents over the Kingdoms of England, Scotland, and Ireland, namely the Dutch Prince of Orange King William III (& II) and his spouse (and first cousin) Queen Mary II. Their joint reign began in February 1689 after they were offered the throne by the Convention Parliament irregularly summoned by William after his successful invasion of England in February 1689, the so-called Glorious Revolution. They replaced James II (& VII), Mary's father, who fled the country. Parliament offered William and Mary a co-regency, at the couple's behest. After Mary died in 1694, William ruled alone until his death in 1702. William and Mary were childless and were ultimately succeeded by Mary's younger sister, Anne.
