Marcus Didius Julianus was Roman emperor from March to June 193, during the Year of the Five Emperors. Julianus had a promising political career, governing several provinces, including Dalmatia and Germania Inferior, and defeated the Chauci and Chatti, two invading Germanic tribes. He was even appointed to the consulship in 175 along with Pertinax as a reward, before being demoted by Commodus. After this demotion, his early, promising political career languished.

Year of the Five Emperors
The Year of the Five Emperors was AD 193, in which five men claimed the title of Roman emperor: Pertinax, Didius Julianus, Pescennius Niger, Clodius Albinus, and Septimius Severus. This year started a period of civil war when multiple rulers vied for the chance to become emperor.

Coin of Clodius Albinus. This coin celebrates Saeculum Frugiferum, the embodiment of a "fruitful era", probably Ba'al Hammon, a Phoenician divinity worshipped in North Africa, whence Clodius came.
