Fausta was the daughter of the Roman Emperor Maximianus. To seal the alliance between them for control of the Tetrarchy, Maximianus married her to Constantine the Great in AD 307.
It is suspected that Fausta was fiercely anti-Christian and plotting the Roman empire's return to paganism behind her husband's back. Although the real reasons are not clear, Constantine eventually put her to death along with Crispus, his eldest son by a previous marriage to Minervina , in 326 AD. Eusebius of Caesarea suspected step-mother and step-son to be lovers to each other.
Her sons became Roman Emperors Constantine II (reigned 337 - 340), Constantius II (reigned 337 - 361) and Constans (reigned 337 - 350).
