History & Evolution
The first settlement in Istanbul’s history dates back to the 3rd Century BC. The city was a major trading and commercial centre during that time. The major turnaround in the history of Istanbul took place in the 4th century when it was named the capital of Roman Empire.

As soon as Istanbul became the capital city the construction of many temples, official buildings, palaces, hamams and hippodrome started in the region. It remained the capital of the Roman Empire (Byzantine) for a long period.

The city has seen many battles due to its importance. Istanbul was invaded by the Arabs in the 7th and 8th centuries & the Bulgars in the 9th and 10th. The city was finally conquered and became a part of Byzantium empire in 1261. In 1453 Istanbul became the capital city of Ottoman Empire. The reconstruction of the city took place and many buildings that were destroyed in the earlier wars were recreated. The period when Istanbul was ruled by Suleyman is considered as the most important period in the History of Ottoman Empire.

The empire started declining in the 18th century. World War I led to the occupation of Istanbul by allied forces. Mustafa Kemal Ataturk led the Turkish army for a war of freedom and the Turkey of Republic was formed in 1932. Although the capital of Turkey has now been moved to Ankara but Istanbul still is the cultural and commercial center of Turkey.
