Licinius, born around 265 AD, was a significant figure in the history of the Roman Empire. His full name was Valerius Licinianus Licinius, and he rose through the ranks to become one of the four Tetrarchs during the period known as the Tetrarchy, a system established by Diocletian to govern the vast Roman territories more effectively.
Licinius was of Illyrian origin, born in Moesia Superior. His military career began under Galerius, one of Diocletian's original Caesars. Licinius's loyalty and military prowess were recognized when he was appointed as Augustus in the West in 308 AD by Galerius after the abdication of Diocletian and Maximian. His domain included the Balkans, Italy, and parts of Africa.
After his defeat, Licinius was initially spared but later executed in 325 AD on charges of treason, following a failed plot against Constantine. His execution was part of Constantine's effort to consolidate power and remove potential rivals.
Licinius's rule is noted for his attempt to balance the traditional Roman religion with the growing influence of Christianity. His reign marked the beginning of the end for the Tetrarchy, as Constantine's victory led to his establishment as the sole ruler of the Roman Empire.
