The House of Hanover is a royal dynasty that originated in Germany and became prominent in Britain. It began with George I, who ascended to the British throne in 1714 after the death of Queen Anne. The house ruled Britain and its territories for over a century, influencing the development of the modern British monarchy. The House of Hanover produced several notable monarchs, including George II, George III, and Queen Victoria. The dynasty ended with Queen Victoria's death in 1901, leading to the rise of the House of Saxe-Coburg and Gotha, which later became the House of Windsor during World War I.
