The dynasty ruled until 1901, with notable monarchs including George II, George III, and Queen Victoria. The House of Hanover is known for its significant influence on British history, particularly during the Georgian era. The dynasty's reign saw the expansion of the British Empire and important political changes, including the development of the modern parliamentary system. The house eventually merged with the House of Saxe-Coburg and Gotha in 1901.
