- Byzantium was going to be a new power center well suited for the control of the eastern territories of the Roman Empire that had become so vast.
- The location was strategic: a point midway between Europe and Asia, and the control of the Bosphorus Strait, the way communicating the Black Sea and the Mediterranean.
- Byzantium was going to be the end tradepoint of the Silk Road that connected Asia and Europe in the trade of species and other valued products at the time.
- We could add another good reason, which is the proximity to the holy places of Christianity in Jerusalem.
