Istanbul is Turkey's most developed and largest city, with the latest discoveries indicating that the history of human habitation there goes back some 400,000 years. The purple years of Istanbul may have started in 330 when Emperor Constantine declared the city the capital of his empire – royal purple is the colour of the Byzantine imperial family. Until 1453, when it was conquered by the Ottomans, the city served as the capital of the Byzantine Empire. During the reign of the Byzantines, Istanbul was adorned with a number of great monuments, which made it the most magnificent city in the world, even during the declining years of the empire.
