Coloman of Hungary, Bishop of Győr

Coloman (c. 1317–1375) was the illegitimate son of King Charles I of Hungary, born to a concubine on Csepel Island. Destined for the Church, he became bishop of Győr by papal bull in 1337, aged about twenty.

He accompanied his half-brother Louis I on the Neapolitan campaign of 1350, but was imprisoned in 1353, accused of conspiring against the king. Freed by 1359 and restored to his see, he remained bishop of Győr until his death.
