Answer:
After the conquest, Sultan Mehmed II transferred the capital of the Ottoman Empire from Edirne to Constantinople. Constantinople was transformed into an Islamic city: the Hagia Sophia became a mosque, and the city eventually became known as Istanbul.
Explanation:
Constantinople was the heart of the Byzantine Empire. It became the capital of the Ottoman Empire when it was conquered in 1453 by the Ottoman Sultan Mehmet II.
Mehmet slaughtered many of the population and forced the rest into exile, later repopulating the city by importing people from elsewhere in Ottoman territory.
Mehmet renamed Constantinople Istanbul – the 'city of Islam' - and set about rebuilding it, both physically and politically, as his capital.
Economics
Istanbul became not only a political and military capital, but because of its position at the junction of Europe, Africa, and Asia, one of the great trade centres of the world. Another important city was Bursa, which was a centre of the silk trade.
Some of the later Ottoman conquests were clearly intended to give them control of other trade routes.
Among the goods traded were:
Silk and other cloth
Musk
Rhubarb
Porcelain from China
Spices such as pepper
Dyestuffs such as indigo
The economic strength of the Empire also owed much to Mehmet's policy of increasing the number of traders and artisans in the Empire.
He first encouraged merchants to move to Istanbul, and later forcibly resettled merchants from captured territories such as Caffa.
He also encouraged Jewish traders from Europe to migrate to Istanbul and set up in business there. Later rulers continued these policies.
