Martinian was a short-lived emperor appointed to the post to symbolically disfranchise Constantine. Constantine and Licinius met in battle with the latter suffering a resounding defeat. Licinius and Martinian fled to Byzantium. Constantine chased them both here and another battle was fought and again they were defeated. The two were captured and exiled separately where sometime later they were executed.
