Gordian III

Gordian III (Latin: Marcus Antonius Gordianus; 20 January 225 – c. February 244) was Roman emperor from 238 to 244. At the age of 13, he became the second-youngest sole emperor of the united Roman Empire. Gordian was the son of Maecia Faustina and her husband Junius Balbus, who died before 238. Their names are mentioned in the unreliable Historia Augusta. Maecia was the daughter of Emperor Gordian I and sister of Emperor Gordian II. Very little is known of his early life before his acclamation.
