(c. 1150-1228) English priest who was mainly responsible for drafting the charter of rights, the Magna Carta.
He studied in Paris, where he became chancellor of the university, and in 1206 was created a cardinal. When in 1207 Pope Innocent III secured Langton's election as archbishop of Canterbury, King John refused to recognize him, and he was not allowed to enter England until 1213. He supported the barons in their struggle against John and worked for revisions to both church and state policies.
