Galerius was a Roman emperor of the Tetrarchy, made Caesar under Diocletian in 293 and senior emperor in the east from 305 to 311. He fought on the Danube against the Carpi and other peoples and won a major victory over the Persian king Narseh in 298. A leading force behind the Great Persecution of Christians, he ended it by an edict of toleration shortly before his death.
