Flavia Maxima Fausta Augusta was a Roman empress. She was the daughter of Maximian and wife of Constantine the Great, who had her executed and excluded from all official accounts for unknown reasons. Historians Zosimus and Zonaras reported that she was executed for adultery with her stepson, Crispus.

Maximian, nicknamed Herculius, was Roman emperor from 286 to 305. He was Caesar from 285 to 286, then Augustus from 286 to 305. He shared the latter title with his co-emperor and superior, Diocletian, whose political brain complemented Maximian's military brawn. Maximian established his residence at Trier but spent most of his time on campaign. In late 285, he suppressed rebels in Gaul known as the Bagaudae. From 285 to 288, he fought against Germanic tribes along the Rhine frontier. Together with Diocletian, he launched a scorched earth campaign deep into Alamannic territory in 288, refortifying the frontier.
