"Flavia Julia Constantia (after 293 – c. 330) was the daughter of the Roman Emperor Constantius Chlorus and his second wife, Flavia Maximiana Theodora.
In 313, Emperor Constantine the Great, who was the half-brother of Constantia, gave her in marriage to his co-emperor Licinius, on occasion of their meeting in Mediolanum. She bore a son, Valerius Licinianus Licinius, in 315, and when the struggle between Constantine and Licinius began in 316, she stayed on her husband's side. A second war started between the two emperors in 324; after Licinius' defeat, Constantia interceded with Constantine for her husband's life. Constantine spared Licinius' life, and obliged him to live in Thessalonica as a private citizen, but the following year (325), he ordered that Licinius be killed. A second blow for Constantia was the death, also by order of Constantine, of her son Valerius." - (en.wikipedia.org 11.08.2021)
