The relationship between William and Mary as king and queen centers on their joint monarchy following the Glorious Revolution. William III and Mary II were married, first cousins, and ruled England, Scotland, and Ireland together from 1689 until Mary’s death in 1694, with William continuing as sole king until 1702. Their reign established constitutional monarchy and parliamentary supremacy, reshaping British political life. This overview explains their partnership, roles, and historical significance in durable, factual terms.
Historical Background and Accession
William III, a Dutch prince, and Mary II, the Protestant daughter of James II, came to power after the bloodless transition of 1688. Parliament offered the throne jointly to them, conditioning their rule on acceptance of the Bill of Rights 1689. This settlement limited royal authority, affirmed parliamentary rights, and clarified succession, establishing a framework for constitutional monarchy that influenced British governance for centuries.

While partnership dynamics varied, their rule functioned as a shared monarchy, with both titled king and queen, and joint authority over governance, law, and foreign policy.
