Flavia Julia from Promptuarii Iconum Insigniorum.
|Empress of the Roman Empire|
|Tenure||313-324 (concurrently with Fausta)|
|Issue||Valerius Licinianus Licinius|
|Father||Roman Emperor Constantius Chlorus|
|Mother||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.
In the following years, Constantia lived at her brother's court, receiving honors (her title was nobilissima femina). Constantia was her brother's favourite sister and proof of such favour is that he minted coins with her image and with the title "Constantia Soror Constantini AVG," or, "Constantia, Sister of Constantine Augustus" ("AVG" is an abbreviation of "Augustus," the center consonant being a "manuscript U," not a "V"). She converted to Christianity, supporting the Arian party at the First Council of Nicaea (325).
