(1449–1453) three chances to surrender the city. He guaranteed the safety of the city's residents, with their riches, beliefs, and honor. Constantine valiantly refused the offer. After more than a month of fighting, Mehmed's advisors were beginning to lose hope. Against their counsel, Mehmed continued to fight. The night before the final assault, he studied previous attempts to take the city to distinguish potentially successful approaches. On the morning of 29 May 1453 the sultan ordered Adzan (the call to prayer).Eversley, Lord. The Turkish Empire from 1288 to 1914. 3rd ed. Howard Fertig. New York: Howard Fertig Inc., 1924. p. 2 This was not a regular prayer session for religious reasons but rather a scare tactic: the sight of the entire Ottoman army getting on their knees to pray provided an intimidating display of unity to the Byzantine forces designed to overcome their minds before their bodies. Once the fighting started, it went on for forty-eight days. The wall was beginning to collapse when Constantine sent a letter to the pope asking for help. In response, the Papacy sent five ships full of reinforcements, weapons, and supplies. Another defense tactic involved Constantine blocking off the

was still holding on after this defeat, the sultan set up his secret weapon, a huge mobile tower. This tower could hold many soldiers who could be at the same level as the walls of the city, making it easier for them to break into Constantinople. The first group of Ottomans who entered the city were killed almost immediately, with the effect that the other Ottomans began to retreat. Witnessing this, the sultan encouraged his soldiers. Soon after the sultan's encouragement the Ottomans broke the wall in two places and entered the city. In a last attempt to protect it, Constantine attacked the enemy sword raised; however, he was defeated and killed. Finally, Constantinople was under Ottoman rule.

Imperial capital

By 1459, the Sultan dedicated a lot of energy to bringing prosperity to Constantinople. In several quarters of the city pious foundations were created; these areas consisted of a theological college, a school (or a Madrasa, usually connected to the mosque), a public kitchen, and a mosque. In the same year, Mehmed sent out orders that any Greeks who had left Constantinople as slaves or refugees should be allowed to return. These actions led it to become a once again thriving capital city, now of the Ottoman Empire.

, Constantinople acquired additional importance in Muslim eyes. Mosques built by Sultan Suleiman I and his successors gave the city the unique appearance it still preserves today. The individual communities, though, still lived in self-contained areas. A 16th century Chinese geographical treatise described Constantinople/Istanbul as follows:
Its city has two walls. A sovereign prince lives in the city. There are Muslims wearing headwraps and Han-Chinese. There are translators. People cultivated dry fields. It has no products.
The statement that there were translators suggests it was a multilingual, multicultural, cosmopolitan city. Although the claim that there were "Han-Chinese" is dubious. Until the eighteenth century, living standards were at least equal to most of Europe. For example, the development of urban craftsmen's wages was on a level similar to southern and central Europe during the sixteenth to eighteenth century.

As the years passed the population increased, from about 80,000 at the death of Mehmet, to 300,000 by the 18th century, and 400,000 in 1800.

The U.S. State Department began using "Istanbul" in May 1930. With the establishment of the new Turkish Republic, built on a wave of nationalism, there was a mass exodus of much of the Greek and Armenian population from Istanbul, which had ceased to be the capital. After the pogrom of 1955, the remaining fraction also departed. In the early years of the republic, Istanbul was overlooked in favour of Ankara, the new capital. However, starting from the late 1940s and early 1950s, Istanbul underwent a great structural change, as new public squares (such as Taksim Square), boulevards and avenues were constructed throughout the city; sometimes at the expense of the demolition of many historical buildings. In September 1955, many ethnic Greek businesses were destroyed during the Istanbul pogrom. This accelerated the departure of Greeks from the city and Turkey. Jews, Armenians, and Georgians were also targeted. Starting from the 1970s, the population of Istanbul began to rapidly increase, as people from
