Gloucester had been one of the barons in opposition to John and was among the 25 appointed in 1215 to see that Magna Carta was carried out. Consequently he was excommunicated by Innocent III when John did his deal with the papacy. After John's death, Gloucester supported the dauphin's attempt on the throne and was captured at the battle of Lincoln in 1217. In later years he campaigned against the Welsh.
