Robert Kett
Robert Kett (c. 1492–1549) was a landowner of Wymondham in Norfolk, thought to have been a tanner, who led Kett's Rebellion against the enclosure of common lands during the Duke of Somerset's protectorate. After riots in July 1549 he gathered some sixteen thousand followers on Mousehold Heath, enforced camp discipline, and presented demands to the crown to limit the gentry's power and protect communal resources.
His men took Norwich on 1 August, but he rejected a royal pardon. On 27 August John Dudley, Earl of Warwick, crushed the rebels at Dussindale. Kett was convicted of treason and hanged from Norwich Castle on 7 December 1549.
