Educated at
Oxford, where he was awarded a master's degree in 1286 and a doctorate in 1306, he entered the service of Bishop
Bitton in Exeter in 1300 and succeeded him in 1308. As well as duties in the diocese, he had already been on royal duty in
Aquitaine and from then on combined his episcopal activities, which he never neglected, with service as a royal adviser and envoy. He was sent often to
France and also to the
Low Countries, as well as taking part in negotiations with
Scotland. From 1313 he sat in
Parliament and from 1315 was a member of the
Privy Council. With the country subject to increasing tensions under the stormy rule of King
Edward II, he accepted the difficult post of
Treasurer in 1320. After the king was forced to exile the
Despensers, a move he considered unwise, he resigned in 1321 and gave his reasons in a letter which annoyed the king. Reappointed in 1322, he faced increasing problems in raising revenue from a country suffering from civil wars and the cost of external wars in Scotland and Aquitaine. Though a truce was negotiated with the Scots, he was party to seizures of lands in England, including estates of Queen
Isabella. She was already antagonistic to Stapledon, accusing him of abandoning her when she fled with her son to France and now regarded him as an enemy. Removed from office in 1325, after Isabella invaded England he went to London, where the people of the city were intensely hostile to him and his brother. After his house was looted and burned, both were murdered in the street on 15 October 1326 and his head was sent to the queen. As well as his services to the Catholic church in the west of England and to the Crown, he also encouraged architecture, archiving and learning. With his brother Richard, in 1314 he founded Stapledon Hall at Oxford, which has since become
Exeter College. ==Monument==
