The last queen of England before the establishment of the constitutional monarchy was Queen Anne, who reigned from 1702 to 1714. Her reign marked the transition from absolute monarchy to a more parliamentary system of governance, established following the Glorious Revolution of 1688. Anne oversaw significant events, including the unification of England and Scotland into Great Britain in 1707. After her death, the Act of Settlement 1701 ensured that the monarchy would remain under the line of succession defined by Parliament, thereby exercising an early form of constitutional monarchy where the power of the crown was limited by legislative authority.
