Prince William Augustus was born in Leicester Fields (now Leicester Square) Westminster, London, he was the third and youngest son of George II of Great Britain and Caroline of Ansbach, and was Duke of Cumberland from 1726. He is best remembered for his role in putting down the Jacobite Rising at the Battle of Culloden in 1746; this success made him immensely popular throughout Britain. Cumberland's final years were lived out during the first years of the reign of his nephew, George III, who took to the throne on the death of William's father on 25 October 1760: Cumberland became a very influential advisor to the King and was instrumental in establishing the First Rockingham Ministry. Cumberland was obese and never fully recovered from a leg wound from a musket ball at the Battle of Dettingen in 1743. He suffered a stroke in August 1760 and died unmarried at the age of 44 on 31 October 1765.
