He held the imperial rank of caesar between March 317 and September 324,[6] while his father was augustus, and he was twice Roman consul.

[4][7] After losing a civil war, his father lost power and both he and Licinius Junior were eventually put to death.

[1]On the 1 March 317 Licinius II was raised to the imperial rank of caesar by agreement between his father and Constantine.

[6][5] Licinius was mentioned in the inscription of a Roman milestone from Viennensis as Constantini Aug. sororis filius, 'the son of the sister of Constantine Augustus'.

[12] The largitio bowls were decorated with portraits of the two emperors, with inscriptions celebrating the quinquennalia of Licinius II as well as a vota (vow of good rulership) for a decennalia.

[13] Immediately after his father's defeat and capitulation the Licinius II was stripped of the title of caesar.

[6] He fell victim to the augustus's suspicions and died at Pola, possibly in the context of the execution of Crispus.

[16] Like his father, Licinius II was the subject of a posthumous damnatio memoriae and their names were expunged from official inscriptions.

[6] This son of the augustus was, by legislation, forced into slavery in the imperial textile factories (gynaeceum) in Carthage, Africa.
