died July 9, 1228, Slindon, Sussex, Eng.
English cardinal and archbishop of Canterbury (1207–28).
Langton was living in Rome when Innocent III nominated him as archbishop of Canterbury to settle a disputed election. When King John refused to allow him into England, the pope excommunicated John (1209). John finally submitted and received Langton in 1213. The new archbishop encouraged baronial opposition to the king but opposed violence. He was present at the signing of the Magna Carta (1215) and influenced its provisions on ecclesiastical liberties.
