"Gordian II (Latin: Marcus Antonius Gordianus Sempronianus Romanus Africanus Augustus; c. 192 – April 12, 238) was Roman Emperor for 21 days with his father Gordian I in 238, the Year of the Six Emperors. Seeking to overthrow Emperor Maximinus Thrax, he died in battle outside Carthage. Since he died before his father, Gordian II had the shortest reign of any Roman Emperor in the whole of the Empire´s history, at 21 days." - (en.wikipedia.org 30.01.2020)
