Candidianus (son of Galerius)

Candidianus (c. 296–313) was the son of the Roman Emperor Galerius and step-son of Galeria Valeria, the wife of Galerius and daughter of Diocletian.
Life and execution.
Candidianus was the son of Galerius and a concubine whose name has not been recorded. He was later adopted by Galerius's legitimate wife, Galeria Valeria, who had no children of her own. Lactantius records that Galerius intended to make Candidianus a Caesar, or junior emperor, upon the celebration of his vicennalia in 312. However, Galerius perished in 311 while preparations for the celebration were underway and was succeeded by Maximinus Daia and Licinius.
Along with Severianus, son of the deceased emperor Flavius Valerius Severus, Candidianus feared the evil intentions of Licinius and fled to the court of Maximinus Daia where he resided until 313. It was probably about this time that young Candidianus was betrothed to the daughter of Daia who was seven years old at the time.
When Daia went to war against Licinius in 313, Candidianus was captured after Licinius emerged victorious and Daia perished. According to Lactantius, Candidianus presented himself at the court of Licinius and was received with honor. However, as soon as the youth felt himself safe, Licinius had him executed. His unnamed betrothed and her brother, Maximus, were also slain at about the same time.
Practically all we know about Candidianus comes from Lactantius.
