In October 1361 the pope appointed him bishop of London, and he was soon serving the king as an ambassador and in other ways. In 1375 he succeeded William Whittlesey as archbishop of Canterbury, and during the rest of his life was a partisan of John of Gaunt.
In January 1380 Sudbury became chancellor of England, and the insurgent peasants regarded him as one of the principal authors of their woes. Having released John Ball from his prison at Maidstone, the Kentish insurgents attacked and damaged the archbishop's property at Canterbury and Lambeth; then, rushing into the Tower of London, they seized the archbishop himself.
Sudbury was dragged to Tower Hill and, on June 14 1381, was beheaded. His body was afterwards buried in Canterbury Cathedral. Sudbury rebuilt part of the church of St Gregory at Sudbury, and with his brother, John of Chertsey, he founded a college in this town; he also did some building at Canterbury. His father was Nigel Theobald, and he is sometimes called Simon Theobald or Tybald.
