Magnus Magnentius ( 303 – 10 August 353) was a Roman general and usurper against Constantius II. Of Germanic descent, Magnentius served with distinction in Gaul, where the army chose him as a replacement for the unpopular emperor Constans. Acclaimed Augustus on 18 January 350, Magnentius quickly killed Constans and gained control over most of the Western Empire. The Eastern emperor Constantius II, brother of Constans, refused to acknowledge Magnentius's legitimacy, leading to three years of civil war. Decisively defeated at the Battle of Mons Seleucus, Magnentius killed himself on 10 August 35

Flavia Valeria Constantina (also sometimes called Constantia and Constantiana; ; b. after 307/before 317 – d. 354), later known as Saint Constance, was the eldest daughter of Roman emperor Constantine the Great and his second wife Fausta, daughter of Emperor Maximian. Constantina may have received the title of Augusta from her father, and is venerated as a saint, having developed a medieval legend wildly at variance with what is known of her actual character.
