At the age of 54, after the death of Queen Anne, George I ascended the British throne as the first monarch of the House of Hanover. Although over fifty Catholics bore closer blood relationships to Anne, the Act of Settlement of 1701 prohibited Catholics from inheriting the British throne. George, however, was Anne's closest living Protestant relative. In reaction, the Jacobites attempted to depose George and replace him with Anne's Catholic half-brother, James Stewart, but their attempts failed.
During George's reign the powers of the monarchy diminished and Britain began a transition to the modern system of cabinet government led by a prime minister. Towards the end of his reign, actual power was held by Sir Robert Walpole, Great Britain's first de facto prime minister. George died in 1727 on a trip to his native Hanover, where he was buried.
