Licinius in Harpers Dictionary of Classical Antiquities

A Roman emperor, ruling A.D. 307-324. He was a Dacian peasant by birth, and was raised to the rank of Augustus by the emperor Galerius. He afterwards had the dominion of the East. He carried on war first with Maximinus II., whom he defeated A.D. 314, and subsequently with Constantine, by whom he was in his turn defeated, 315. A second war broke out between Licinius and Constantine in 323, in which Licinius was not only defeated, but deprived of his throne. In the following year he was put to death by Constantine, 324.
