Severus Alexander (208–235)
Born 208 CE, died 235 CE.
Marcus Aurelius Severus Alexander (1 October 208 – March 235), also known as Alexander Severus, was Roman emperor from 222 until 235. He was the last emperor from the Severan dynasty and, at the age of 13, became the youngest sole emperor of the united Roman Empire. Alexander became emperor at age 13, succeeding his slain cousin, Emperor Elagabalus as his heir. Alexander and Elagabalus were both grandsons of Julia Maesa, the sister of the empress Julia Domna, who had arranged for Elagabalus's acclamation as emperor by the Third Gallic Legion. Elagabalus had been murdered along with his mother Julia Soaemias by his own guards, who, as a mark of contempt, had the two bodies cast into the Tiber river. Alexander's 13-year reign was the longest reign of a sole emperor since Antoninus Pius and in peace proved prosperous. However, Rome faced military threats from the rising power of the Sassanid Empire, as well as growing incursions from the tribes of Germania. Alexander managed to check the threat of the Sassanids, but attempted to bring peace by engaging in diplomacy and bribery when campaigning against Germanic tribes.
