Constantius Chlorus

Constantius I was a Roman emperor. He ruled as Caesar from 293 to 305 and as Augustus from 305 to 306. He was the junior colleague of the Augustus Maximian under the Tetrarchy and succeeded him as senior co-emperor of the western part of the empire. Constantius ruled the West while Galerius was Augustus in the East. He was the father of Constantine the Great and founder of the Constantinian dynasty. After his death he became known as Chlorus, but the nickname does not appear in records before the sixth century.
