Flavia Maximiana Theodora

Flavia Maximiana Theodora (died before 337) was a Roman empress as the wife of Constantius Chlorus.

Early life
She is often referred to as a stepdaughter of Emperor Maximian by ancient sources, leading to claims by historians Otto Seeck and Ernest Stein that she was born from an earlier marriage between Eutropia, wife of Maximian, and Afranius Hannibalianus. This man was consul in 292 and praetorian prefect under Diocletian.

Timothy Barnes challenges this view, arguing that all "stepdaughter sources" derive their information from the hypothetical 4th century Enmannsche Kaisergeschichte, which Barnes considers unreliable, while sources he considers to be more reliable refer to Theodora as Maximian's daughter, rather than his stepdaughter. He concludes that she was born to an earlier wife of Maximian, possibly one of Hannibalianus's daughters. Although Julia Hillner agreed with the idea of Theodora being Maximian's biological daughter, she also observed that Barnes' theory does not explain why one of Theodora's daughters was named Eutropia. She believes that Theodora was the daughter of both Maximian and Eutropia. She agrees with Barnes that the "stepdaughter sources" are the result of later Constantinian propaganda, but argues that Afranius was instead Eutropia's brother, thus explaining why Theordora named one of her daughter Eutropia, and one of her sons Hannibalianus.

Marriage
In 293, Theodora married Constantius Chlorus, the junior co-emperor of Maximian, after he had set aside Helena, mother of his son Constantine, to strengthen his political position. The couple had six children. Through her son Julius Constantius, she would become the grandmother of the emperor Julian.

After the death of her stepson Constantine, several of her male descendants were massacred, which Julian explicitly blamed Constantius II for. Constantine's successors proceeded to print coins of Theodora, presumably in an attempt to distance themselves from the massacre.
