The Roman emperor Caesar Galerius, also known as Galerius Valerius Maximianus, was an important ruler of the late Roman Empire, particularly noted for his role during the tetrarchy of Diocletian. Born around 250 AD in the region of Illyria, in present-day Serbia, Galerius began his career as a soldier and gradually ascended to the heights of imperial power.
In 293 AD, Emperor Diocletian divided the Roman Empire into two halves, appointing two Augusti (Diocletian himself and Maximian) and two Caesars (Constantius Chlorus and Galerius) in a system known as the tetrarchy. Galerius was appointed Caesar of the East and was responsible for overseeing the eastern provinces of the Empire.
During his reign, Galerius was involved in numerous military campaigns against internal and external enemies of the Empire. He fought against the Persians, the Sassanids, and was involved in suppressing revolts in various eastern provinces.
One of the most well-known aspects of Galerius's reign was his persecution of Christians. It is believed that he issued an edict in 303 AD, along with Emperor Diocletian, ordering the destruction of Christian churches, confiscation of their properties, and imprisonment of their leaders. This persecution was particularly harsh in the eastern provinces, under Galerius's direct control.
Galerius ruled until his death in 311 AD. His successor, Emperor Licinius, issued an edict of religious tolerance, ending the persecution of Christians in the Eastern Roman Empire. Galerius's figure is complex and controversial: some consider him a skilled administrator and effective military commander, while others see him as a despot who ruthlessly persecuted his political and religious opponents.
