Constantius Chlorus was a Roman Emperor who ruled from 293 to 306 AD. He was part of the Tetrarchy, a system established by Diocletian to manage the vast Roman Empire by dividing it into four regions, each ruled by a co-emperor. Constantius was responsible for the western provinces and is known for his military campaigns against the Picts in Britain. Born around 250 AD, Constantius was the son of a Roman officer and became known for his administrative skills and military prowess. He was the father of Constantine the Great, who would later reunite the empire and establish Christianity as a major religion. Constantius's reign was marked by stability and efforts to strengthen the empire's borders.
