The Hanoverian dynasty became the British royal family after Queen Anne died without an heir in 1714. The first Hanoverian kings, George I and George II, were German and did not speak English fluently. Frederick, Prince of Wales and heir to the throne, was allegedly poisoned. His son George III became king at age 22 and lost the American colonies. The Hanoverian dynasty ruled until Queen Victoria in 1837, bringing more stability as monarchs who spoke English and were born in Britain.
