Severus II (d. 307 CE) was a Roman emperor who ruled briefly from 306 to 307 CE during the turbulent period of the Tetrarchy. Originally a trusted military officer and friend of Emperor Galerius, Severus was appointed Caesar in 305 CE and elevated to Augustus in the West after the death of Constantius Chlorus in 306. However, his authority was challenged almost immediately by Constantine the Great, who was declared emperor by his troops, and by Maxentius, the son of former emperor Maximian. Sent to suppress Maxentius in Rome, Severus was betrayed by his own men, captured, and later executed or forced to commit suicide in 307 CE. His brief and ill-fated reign highlights the instability of the late Roman imperial system.
