Year 238 (CCXXXVIII) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Pius and Pontianus (or, less frequently, year 991 Ab urbe condita). The denomination 238 for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.
c. March – Roman subjects in Africa revolt against Maximinus. The elderly Gordian yields to public demand that he succeed Maximinus and rules jointly with his 46-year-old son Gordian II.
c. May – The Senate outlaws Maximinus for his bloodthirsty proscriptions in Ancient Rome and nominates two of its members, Pupienus and Balbinus, to the throne.
Maximinus advances to the town Aquileia in northern Italy; his army suffers from famine and disease, while the city is besieged. Soldiers of Legio II Parthica kill him in his tent, along with his son Maximinus (who is appointed co-emperor). Their corpses are decapitated and their heads carried to Rome.
c. August – The Praetorian Guard storms the palace and captures Pupienus and Balbinus. They are dragged naked through the streets of Rome and executed. On the same day Gordian III, age 13, is proclaimed the new emperor.[2]Timesitheus becomes his tutor and advisor.
