Death of Constantine – Gibbon’s Decline and Fall of the Roman Empire Chapter 18 Part 2
Constantine died in Nicomedia in 337 after a short illness. He had lived to 64, a good age for the time. The death of Constantine ended one of the longest reigns in the history of the empire. His death came just after he had celebrated his thirtieth year as emperor, something only Augustus had previously achieved. It was fitting that he was buried in Constantinople, the city he founded.
