Licinius

Licinius (c. 265–325), born to a Dacian peasant family in Moesia Superior, was a friend of Galerius, who made him Augustus in 308 with charge of the Balkan provinces. After Galerius died in 311, Licinius and Maximinus Daza divided the eastern provinces.

In 313 he married Constantine's half-sister Constantia and jointly issued the Edict of Milan granting toleration to Christians, then defeated Maximinus Daza at Tzirallum and became Augustus of the East. He and Constantine later fell into civil war; he was defeated at Chrysopolis in 324, surrendered, and was executed the following year.
