Detail of Roman Emperor Constantine I (274–337) in Piero della Francesca’s Vision of Constantine, 1458
Though the name Constantine has never been particularly common in the Anglophone world, it’s long enjoyed great popularity in various other forms in Orthodox Christian countries. It derives from the Latin name Constantinus, which in turn derives from Constans (steadfast, constant).
The name became popular in the Orthodox world because of the above-pictured Constantine the Great (Flavius Valerius Aurelius Constantinus Augustus), who ruled from 306–337. He was the first emperor to stop the persecution of Christians, following his religious conversion.
Some historians, however, believe he privately continued worshipping the Roman deities and only converted to Christianity because it was politically expedient.
