The Hanoverian dynasty was a royal family that originated in Germany and ruled Great Britain from 1714 to 1901. It began with King George I, who became king after the Act of Settlement ensured that only Protestant descendants of James VI and I could inherit the throne. The dynasty played a significant role in shaping modern British monarchy and politics. During its reign, the Hanoverians oversaw important events such as the Industrial Revolution and the expansion of the British Empire. Notable monarchs included George III, known for his long reign and challenges during the American Revolution, and Queen Victoria, who presided over a vast empire and significant social changes.
