Probus (c. 232–282 CE) was a Roman emperor who ruled from 276 to 282 CE, during a period of military crises and internal unrest. A skilled general before becoming emperor, Probus spent much of his reign defending the empire’s frontiers, successfully repelling Germanic tribes and restoring Roman control over rebellious provinces. He also worked to rebuild the economy, encouraging agricultural development and employing soldiers in peaceful public works during peacetime. Known for his energy and discipline, Probus was popular with many but eventually faced resentment from the army. In 282 CE, he was murdered by his own troops, paving the way for the rise of Carus as emperor. Probus is often remembered as one of the more competent rulers of the troubled 3rd century.
