Founding of Byzantium (Istanbul)

c. 657 BCE

Istanbul is the largest city in Turkey and spans the Bosphorus strait between Europe and Asia. It began as the Greek colony of Byzantium, founded by settlers from Megara, and in the fourth century the Roman emperor Constantine the Great rebuilt it as his new capital, Constantinople. For over a thousand years it was the heart of the Byzantine Empire, with landmarks such as Hagia Sophia and its great land walls. It was conquered by the Ottomans under Mehmed II and remained the Ottoman capital until the 1920s, when Ankara replaced it. The name Istanbul was officially adopted in the Turkish Republic, and the city is today one of the largest in Europe.
