君士坦提烏斯二世
Not only did Constantina exercise influence on her own, she was inherently, as a female member of the imperial Roman family, a political tool. As a widow, she could be offered in marriage to secure political alliance. This happened twice. In AD 350, in order to attempt a peaceful compromise by arranging marriage, Magnentius offered to marry Constantina and have Constantius II marry his daughter. But Constantius II refused this offer. Shortly after, in AD 351, Constantius II used Constantina for a different political purpose and gave her in marriage to Constantius Gallus who was made "Caesar" in the Eastern Roman Empire and they moved to Antioch.
