Constantinople, the modern Istanbul, strategically situated at the crossing between the empire’s European and Asiatic provinces, and founded in the year 330 by the emperor Constantine I (306–37) on the site of an earlier city named Byzantion. The Byzantines themselves took enormous pride in it: so important a place was it in their eyes that they seldom needed to refer to it by name, preferring to use epithets such as the ‘Queen of Cities’, the ‘Great City’ or just ‘the City’.
