The fascinating history of this pivotal region from the Trojan War to Byzantion's refounding as Constantinople, the new capital of the Roman Empire.
In ancient times, the series of waterways now known as the Turkish Straits, comprising the Dardanelles (or Hellespont), Sea of Marmara and the Bosporus, formed both a divide and a bridge between Europe and Asia. Its western and eastern entrances were guarded, at different times, by two of the most fabled cities of all time: respectively Troy (in Asia) and Byzantion (or Byzantium, on the European coast). The narrow crossing points at the Hellespont and Bosporus were strategically important invasion routes while the waters themselves were vital routes of travel and commerce, particularly the supply of grain from the hinterland of the Black Sea to the Greek cities. This made them sought after prizes and sources of friction between successive empires, Persians, Macedonians and Romans among them, and ensured they were associated with some of the great names of history, from Odysseus to Xerxes, Alexander to Constantine the Great.
