Constantius Chlorus served as Caesar and later Augustus of the West under the Tetrarchy established in 293, making him one of the four co-rulers of the Roman Empire. His nickname "Chlorus," meaning "Pale," reflected a declining health attributed to leukemia, which left him unable to counter Galerius's political maneuvering. He died in York shortly after a successful campaign against the Picts in Britain, having earned the title Britannicus Maximus; his son Constantine would go on to reunite the empire.
Also known as: Constantius I · Flavius Valerius Constantius · Constantius Cloris
What each episode says
Episode 2 (1 mention)
Son-in-law of Maximian and one of the two men raised to Caesar in the Tetrarchy of 293. Brownworth mentions him in the context of completing the four-man ruling structure, and notes at the episode's close that his son Constantine would one day reunite the empire.
“son-in-laws, Galerius and Constantius Cloris, and raised them to the rank of Caesar, junior”
Episode 3 (2 mentions)
Constantine's father and Augustus of the West under the Tetrarchy. His nickname 'Chlorus' (Pale) reflected his declining health — he was likely dying from leukemia and unable to prevent Galerius from installing his own candidates. He died in York the spring after his campaign in Britain against the Picts, having just earned the title Britannicus Maximus.
“In the West, the senior emperor, or Augustus, was Constantine's father, Constantius Cloris,”
“it ignored the fact that both Constantius Cloris and Maximian had ambitious young sons”
