Serving during the disorders of Stephen's reign, Theobald succeeded in forcing peace on the king by refusing to consecrate Stephen's son and heir, Eustace. After Eustace's death in 1153, Stephen recognised his rival Henry of Anjou as his heir, and later Theobald was named regent of the kingdom after Stephen's death. After a long illness, Theobald died in 1161, following which unsuccessful efforts were made to have him canonised as a saint.
