In short: When William III and Princess Anne faced a succession crisis in 1700, the British Parliament took drastic action. By passing the Act of Settlement, they bypassed 57 individuals with stronger hereditary claims to ensure the crown passed to a Protestant line, fundamentally reshaping the British monarchy and its constitutional future.

The Act of Settlement, passed on June 12, 1701, was a direct response to a precarious political moment. King William III was ill and childless, and his sister-in-law, Princess Anne, had recently lost her only surviving child, Prince William, Duke of Gloucester. With the exiled Catholic King James II and his supporters remaining active, Parliament sought to eliminate any ambiguity regarding the future of the throne. By designating Sophia, Electress of Hanover and granddaughter of James I, as the successor, the Act guaranteed that the crown would remain within the Protestant faith.

This legislative maneuver was significant for its exclusion of 57 people who held closer hereditary ties to the throne than Sophia and her son, George I. The Act explicitly barred anyone who held communion with the Church of Rome or married a Catholic from inheriting the crown. This religious requirement was paired with strict constitutional limitations on the monarch's power. It mandated that future sovereigns must join in communion with the Church of England and established that judges would hold office during good behavior rather than at the sovereign's pleasure, protecting the judiciary from royal interference.

Beyond succession, the Act introduced measures to limit foreign influence and royal prerogative. It stipulated that England would not be obliged to engage in war to defend territories not belonging to the English crown—a clear nod to the monarch's Hanoverian interests—and restricted the role of foreigners in government. While some clauses, such as those attempting to curb the Cabinet's power or restrict the monarch's travel, were later repealed or modified, the Act remains a cornerstone of British constitutional law. It successfully established the Hanoverian dynasty and solidified the principle that the succession is a matter of parliamentary statute rather than absolute divine right.
