Labarum was a Roman military standard, later adopted by Emperors as Imperial Standard. Constantine the Great (288?-337), after his conversion to Christianity (312), wove the monogram of Christ into his standard, now known as the "labarum." Hence, labarum is a standard or symbol for which men live and die.
