Prince William Augustus (26 April 1721 [N.S.] – 31 October 1765), was a younger son of George II of Great Britain and Caroline of Ansbach, and Duke of Cumberland from 1726. He is generally best remembered for his role in putting down the Jacobite Rising at the Battle of Culloden in 1746, and as such is also known as "Butcher" Cumberland. After Culloden, he went on to a largely unsuccessful military career, and following the Convention of Klosterzeven in 1757, he never held active military command, and switched his attentions to politics and horse racing.
