William and Mary Proclaimed Co-Rulers of England (1689)
On February 13, 1689, William of Orange and his wife Mary were proclaimed King William III and Queen Mary II of England before a gathered assembly at the Banqueting House in Whitehall. Their joint accession marked the culmination of the Glorious Revolution, which had toppled the Catholic King James II just months earlier. The unprecedented arrangement of a shared crown reshaped the balance of power between monarch and Parliament for generations to come.
The Road to Revolution
James II's brief and turbulent reign had alarmed England's Protestant establishment through his open Catholicism and efforts to expand royal authority at Parliament's expense. When his second wife gave birth to a son in June 1688, fears of a lasting Catholic dynasty pushed a group of prominent nobles, known as the Immortal Seven, to secretly invite William of Orange to intervene. William, Stadtholder of Holland since 1672 and husband to James's Protestant daughter Mary, had his own strategic reasons to accept: he sought England's support against the expansionist ambitions of Louis XIV of France. William landed at Torbay in November 1688 with a fleet and army numbering roughly 21,000 men. James's support collapsed rapidly, and by December he had fled to France, leaving the throne effectively vacant. Parliament, convened as a Convention because no king had summoned it, faced the delicate task of determining England's constitutional future without a reigning monarch. Rather than simply installing William as a conqueror or Mary as a hereditary successor, negotiators crafted a compromise reflecting both dynastic legitimacy and William's insistence on a genuine share of power.
Did You Know?
William III insisted he would not settle for the ceremonial title of King Consort even though Mary held the stronger hereditary claim; Parliament ultimately agreed that he alone would exercise sovereign power for life, an arrangement so unusual that England has never repeated a formal joint monarchy since.
A Novel Joint Monarchy
The solution devised by the Convention Parliament was without precedent in English history: William and Mary would reign together as co-sovereigns, with William exercising the actual governing authority even though Mary held the stronger hereditary claim as James's eldest surviving Protestant child. On February 13, 1689, the Convention formally offered the crown to the couple, and they were proclaimed King and Queen in a ceremony at the Banqueting House. Alongside the offer of the throne, Parliament presented the Declaration of Rights, later enacted as the Bill of Rights 1689, which barred Catholics from the throne, curtailed the monarch's power to suspend laws unilaterally, and affirmed Parliament's control over taxation and standing armies. William reportedly made clear he would not accept a merely ceremonial role subordinate to his wife, and Mary, deferential and devoted to her husband, readily agreed that he should hold the real reins of government. The coronation itself took place on April 11, 1689, at Westminster Abbey, performed by the Bishop of London rather than the Archbishop of Canterbury, who refused to recognize the new monarchs. This arrangement of joint rule, though Mary largely deferred to William, established a template for constitutional limits on royal power that would influence Britain's political development for centuries.
Consequences and Legacy
The proclamation of William and Mary permanently altered the relationship between the English crown and Parliament, cementing principles of constitutional monarchy that had been contested for decades. William used his new position to draw England into his ongoing struggle against Louis XIV, embroiling the country in the Nine Years' War from 1688 to 1697. Ireland and Scotland proved harder to secure; William's forces defeated James II's Jacobite supporters at the Battle of the Boyne in July 1690, a victory still commemorated by Ulster Protestants today. Mary governed capably as regent during William's frequent military campaigns abroad, earning respect in her own right before her death from smallpox in 1694 left William as sole monarch. William continued to rule until his own death in 1702, following complications from a fall off his horse. The events of February 1689 are remembered as the decisive turning point of the Glorious Revolution, a largely bloodless transfer of power in England itself that nonetheless entrenched parliamentary supremacy, religious restrictions on the monarchy that persisted for centuries, and a lasting shift away from absolute royal authority toward the constitutional framework that still underpins the British system of government.
