Overview
Gordian III (; 20 January 224 – February 244) was Roman emperor from 238 to 244. At the age of 14, he became the second-youngest sole emperor of the united Roman Empire; the youngest ever being Severus Alexander, who had assumed the princepship at thirteen. Gordian was the son of Antonia Gordiana and Junius Balbus, who died before 238. Antonia Gordiana was the daughter of Emperor Gordian I and younger sister of Emperor Gordian II. Very little is known of his early life before his acclamation. Gordian had assumed the name of his maternal grandfather in 238.
Rise to power
In 235, following the murder of Emperor Alexander Severus in Moguntiacum (modern Mainz), the capital of the Roman province Germania Superior, Maximinus Thrax was acclaimed emperor. In the following years, there was a growing opposition against Maximinus in the Roman Senate and amongst the majority of the population of Rome. In 238, a rebellion broke out in the Africa Province, where Gordian's grandfather and uncle, Gordian I and II, were proclaimed joint emperors. This revolt was suppressed within a month by Cappellianus, governor of Numidia and a loyal supporter of Maximinus Thrax.
The Senate, showing its hostility towards Maximinus by supporting the Gordiani, elected Pupienus and Balbinus as joint emperors. These senators were not popular men, so the Senate decided to raise Marcus Antonius Gordianus to the rank of Caesar. Maximinus, moving quickly to attack the Senate's newly elected emperors, encountered difficulties marching his army through an Alpine winter. Arriving at Aquileia and short on supplies, Maximinus besieged the city. After four weeks, Maximinus' demoralized army mutinied and the Legio II Parthica murdered him.
