1453–1930: Ottoman and Republican Kostantiniyye

The Christian Orthodox city of Constantinople was now under Ottoman control. As tradition followed for the region, Ottoman soldiers had three days to pillage the city. When Mehmed II on the second day entered Constantinople through the Gate of Charisius (today known as Edirnekapı or Adrianople Gate), it is said that first thing he did was ride his horse to Hagia Sophia, which was not in good shape even though it was avoided in the pillage by strict orders. Displeased by the pillaging, Mehmed II ordered it to end, for it will be the capital of his empire. He then ordered that an imam meet him in Hagia Sophia in order to chant the adhan thus transforming the Orthodox cathedral into a Muslim mosque, solidifying Islamic rule in Constantinople.

Mehmed's main concern with Constantinople had to do with consolidating control over the city and rebuilding its defenses. After 45,000 captives were marched from the city, building projects were commenced immediately after the conquest, which included the repair of the walls, construction of the citadel, and building a new palace. Mehmed issued orders across his empire that Muslims, Christians, and Jews should resettle the city, with Christians and Jews required to pay jizya and Muslims pay Zakat; he demanded that five thousand households needed to be transferred to Constantinople by September. From all over the Islamic empire, prisoners of war and deported people were sent to the city: these people were called "Sürgün" in Turkish (Greek: σουργούνιδες). Two centuries later, Ottoman traveler Evliya Çelebi gave a list of groups introduced into the city with their respective origins. Even today, many quarters of Istanbul, such as Aksaray, Çarşamba, bear the names of the places of origin of their inhabitants. However, many people escaped again from the city, and there were several outbreaks of plague, so that in 1459 Mehmed allowed the deported Greeks to come back to the city.
