Gloucester's death destabilised the succession, as his mother was the only person remaining in the Protestant line to the throne established by the Bill of Rights 1689. Although Anne had ten other pregnancies after the birth of Gloucester, none of them resulted in a child who survived more than briefly after birth. The English parliament did not want the throne to revert to a Catholic, so it passed the Act of Settlement 1701, which settled the throne of England on a cousin of King James, Sophia, Electress of Hanover, and her Protestant heirs. Anne succeeded King William in 1702, and reigned until her death on 1 August 1714. Sophia predeceased her by a few weeks, and so Sophia's son George ascended the throne as the first British monarch of the House of Hanover.
