LANGTON, JOHN (d. 1337), chancellor of England and bishop of Chichester, was a clerk in the royal chancery, and became chancellor in 1292. He obtained several ecclesiastical appointments, but owing to the resistance of Pope Boniface VIII. he failed to secure the bishopric of Ely in 1298, although he was supported by Edward I. and visited Rome to attain his end. Resigning his office as chancellor in 1302, he was chosen bishop of Chichester in 1305, and again became chancellor shortly after the accession of Edward II. in 1307. Langton was one of the “ordainers” elected in 1310, and it was probably his connexion with this body that led to his losing the office of chancellor about this time. He continued, however, to take part in public affairs; mediating between the king and Earl Thomas of Lancaster in 1318, and attempting to do so between Edward and his rebellious barons in 1321. He died in June or July 1337. Langton built the chapterhouse at Chichester, and was a benefactor of the university of Oxford.
