Constantinople remained the official name of the city throughout the Eastern Roman (Byzantine) Empire. But Constantinople was referred to by the natives of the city as the only Greek Πό city Ama (sadeceλιν, Police).

The history of Istanbul can be divided into five major periods: the
Byzantine period The period of Constantinople The
Prehistoric times: The history of Istanbul dates back to three hundred thousand years ago. The first traces of human culture were found during the excavations at the Yarımburgaz cave on the Küçükçekmece Lake. It is thought that Neolithic and Chalcolithic people lived around the lake in this period. During the excavations carried out in various periods, near the Dudullu Lower Palaeolithic period, near the middle Palaeolithic tools were found in the Middle Palaeolithic.
Foundation period and Byzantion:During the excavations at the Marmaray tube gateway for the Istanbul subway in 2008, the ruins of the 6500s BC, where the Cilalı Stone Age continued, were found. . In addition, the remains of Phoenicians were found in Kadıköy. The Thracians founded the city of Semistra near the city in the 13th and 11th centuries BC.

In the city, which had migrated from the Balkans in the 1950s, urban slums came to the fore in urbanization. In the 1960s, apartment-building began near the shanty houses. In the 1970s, housing and transportation problems became more important with rapid population growth. In this period, the increase in the number of automobiles and the increase in traffic as a result of the Bosphorus Bridge was effective in the construction and reached an important point in transportation. The metropolitan area of Istanbul reached a radius of 60 kilometers in 1980, while it was 50 kilometers in the center between 1970 and 1975. The population growth of the 1990s resulted in the expansion of the population to the outside and as a result IETT ‘ and the minibuses tried to close this gap.

Hipodrum Square, known as Sultanahmet Square today, was built by Circus Maximus.
Eastern Roman Empire: Maiden’s Tower is the only artifact from the Byzantine Empire Period in Uskudar.
The eastern Roman Empire ruled for a thousand years in the city and used it as its capital. Due to this feature, there are many Eastern Roman buildings in Istanbul. The most important of these were gathered in Eminönü. The most important of these buildings is the Hagia Sophia Museum, which was opened as a church. The Hagia Sophia is a basilica patriarchal cathedral built by the Roman Emperor Justinian I between 532 and 537 AD. It was converted into a mosque by Fatih Sultan Mehmet in 1453 when it was conquered by the Turks and served as a museum.
One of the important buildings after Hagia Sophia was Fethiye Mosque. As a church, it was built by Mihail Glabas Tarkaniotes, one of the most prominent figures of Eastern Rome at the end of the 13th century.

The mosques are built with a lot of social facilities and constitute a “complex”. The Ottomans are brilliant developers. It protects structures with care even if it does not belong to its own civilization. One of the most beautiful examples of this is the Church of Hagia Irene. There is no corner of the empire where there is no reconstruction. Even some modest neighborhood riches can make a mosque or make a fountain or repair a school. The understanding of society is remarkably strong. Architect Sinan ‘ One of the greatest architects in world history is perhaps an alliance when it is the first.
