Licinius II, also called Licinius Junior or Licinius Caesar. July/August 315 – c. 326), was the son of the Roman emperor Licinius I. He held the imperial rank of Caesar between March 317 and September 324, 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.
