Constantine chose Byzantium, on the Bosporus between Europe and Asia, after defeating Licinius in 324: the site was easy to defend and close to both the Danube and the eastern frontiers. The city was rebuilt on a grand scale in six years, with new walls, the Great Palace, an enlarged Hippodrome, a forum with a porphyry column bearing the emperor’s statue and a senate of its own; like Rome, it was divided into fourteen regions. The ceremonial dedication took place on 11 May 330.

Officially “New Rome”, the city soon took its founder’s name. It became the permanent residence of the eastern emperors and, after the fall of the West, the capital of the Roman state until its capture by the Ottomans in 1453.
