The joint reign of William III and Mary II represents one of the most significant constitutional moments in British history, raising the fundamental question of why William and Mary ruled together rather than as separate sovereigns. Their partnership, which began with the Glorious Revolution of 1688, was not merely a union of affection but a complex political arrangement that reshaped the monarchy. The necessity of their co-rule stemmed from the unique circumstances of the Revolution, the need for legitimacy, and the intricate power dynamics between a Dutch Stadtholder and an English heiress. Understanding this arrangement requires looking at the specific historical pressures that made a diarchy the most viable form of government for England at that precise moment.
The Crisis of 1688 and the Invitation to William
Before examining why they ruled together, one must first understand the crisis that necessitated it. By mid-1688, King James II had alienated the political and religious establishment through his promotion of Catholicism and attempts to consolidate executive power. Facing a potential civil war, a group of influential statesmen known as the "Immortal Seven" secretly invited William of Orange to invade England and take the throne. However, the invitation was not offered to William as an independent monarch; it was contingent upon his marriage to James’s daughter, Mary, the Protestant heir presumptive. This condition was crucial, as it provided the new regime with immediate legitimacy and a direct connection to the existing line of succession, making a partnership the only logical foundation for their rule.
Legitimacy and the Need for a Protestant Heir
Legitimacy was the single most important factor driving the decision for joint rule. William needed a legitimate claim to the English throne to secure the support of the nobility and the people, who were deeply suspicious of foreign invasion. By marrying Mary, William became the rightful king through his wife, inheriting her hereditary right to the throne. Conversely, Mary needed a powerful and politically experienced consort to protect her inheritance from the lingering threat of her Catholic father, James II. A queen regnant ruling alone was a radical concept in 1688; the prevailing political theory, heavily influenced by thinkers like John Locke, generally favored male succession. Therefore, a king consort ruling alongside a queen regnant provided a familiar and stable framework for the transfer of power, ensuring the Protestant succession was beyond doubt.
The Mechanics of Shared Power
The arrangement defied simple categorization, as the titles and powers of William and Mary were carefully negotiated. Upon ascending the throne, they were jointly crowned as "King and Queen," a title that reflected the unique nature of their authority. William, as the son of the Dutch Stadtholder, brought military and diplomatic expertise, while Mary provided the essential English legitimacy. Crucially, William fought long and hard to secure the title of King, equal to Mary’s, rather than being styled as a mere Prince Consort. This struggle highlights that the arrangement was a partnership of equals, designed to combine William's executive experience with Mary's hereditary right, creating a stable dual monarchy capable of navigating the complex European political landscape.
Political Necessity and Public Acceptance
Acceptance by the English public and Parliament was not guaranteed, necessitating the specific structure of their rule. William’s foreign birth and Dutch background made him an unpopular choice for many English subjects. By ruling jointly with his English wife, he was seen less as a conqueror and more as a rightful member of the English royal family. This shared rule helped to bridge the cultural divide and present a united front. Furthermore, the arrangement served as a check on absolute power; while William was the dominant partner in practice, the very existence of Mary as a co-sovereign reinforced the idea of a balanced monarchy. This delicate balance was essential for passing the Bill of Rights 1689, which curtailed royal prerogative and established parliamentary sovereignty.
