George I of Great Britain

George I became king of Great Britain and Ireland following the death of Queen Anne. He was the first Hanoverian monarch, succeeding under the Act of Settlement 1701. His accession established the House of Hanover on the British throne.

George I faced a Jacobite rebellion aimed at restoring the Stuart claimant James Francis Edward Stuart. The rebellion was suppressed by government forces at the Battle of Preston and the Battle of Sheriffmuir. This defeat secured George's throne.

George I ceased attending Cabinet meetings due to his limited English and lack of interest. This led to the development of the cabinet system under a chief minister, Sir Robert Walpole, who became the first de facto Prime Minister. This shift strengthened parliamentary governance.

George I died of a stroke while traveling to Hanover. He was buried in the Leineschloss church in Hanover. His death passed the throne to his son George II. His reign established the Hanoverian dynasty in Britain.
