In addition to this, The statistics show Istanbul is home to the largest immigration population with 166,044 people in each year. Hence, Istanbul city is referred to as a metropolis because it incorporates people from all four corners of the earth. There is one main reason for this majority: Location which smooths the way for trade and transportation between two continents.
Istanbul, joining the Black Sea and the Marmara Sea, is located in the meeting point of the continents Europe and Asia. Therefore, Istanbul Straits, passing through Europe and Asia continents, separates Asia and Europe as well as Istanbul City. Thanks to this valuable location, for over 2500 years, Istanbul has been a host to different communities that came from different lands, various ethnic origins and had miscellaneous cultures.
Today, the estimated population of Istanbul city is 15 million. Some of these residents are in Istanbul because their ancestors once lived in the area. Some are in Istanbul because of the irresistible attraction of the city which arises from its prosperous business opportunities and gorgeous nature.

Romans, Kurds, Rums, Armenians, Arabs, Caucasians, Circassians, Turks, Laz people, Arabs, Jewish people are some basic examples of people who happen to come to Istanbul throughout history.
Although all of these ethnic groups meet in Istanbul, they all have a different story about coming to Istanbul. These stories have a close relationship with the history of these various ethnic origins because multiculturalism of a city is not something apart from history.

Rums
It is believed that the Asian side of Istanbul was a host to Greek colonists led by King Byzas around 3000 BC. They founded a colony and named it as Byzantium, the Greek name for a city on the Bosphorus. Resources indicate that the reason for King Byzas to come this land was a suggestion from an oracle of Delphi who told him to settle across from the “land of the blind ones.” Byzas concluded, earlier settlers must have been “blind” to not to notice this location at the entrance of the Bosphorus Strait. This proved an auspicious decision by Byzas, as history has shown Istanbul’s location important far beyond what these early Greek settlers might have conceived.
Today, Rums, descendants of Greeks, have a smaller population in Istanbul than in the past. Turkish government decreased the numbers of Rum people because of its political interests. Before the diminishment, the population of Rum people was around 70,000 in 1970 but today it is around 2500. Rums in Istanbul, who are mostly connected to the Orthodox Church, speak Greek with a dialect peculiar to İstanbul. Most of them used to live around Fener and Balat.

Romans
When a stranger look at the silhouette of Istanbul, which is graced with minarets, it might be difficult for him to believe Istanbul was once the heart of the Christian Roman Empire. However, if you start wandering around the streets and look carefully, you can easily notice the remains of the Christian Roman Empire. How did it happen?
After King Byzas founded the colony of Byzantium, around early 100’ BC, Roman Empire conquered Byzantium. In 306 AD, Emperor Constantine the Great entitled Byzantium as the capital of the Eastern Roman Empire. After that time, the city earned a reputation as Constantinople.
Now, It is not certain how many Roman descendants live in Istanbul because of the mixed ancestry. One known fact is that not only Along with the Roman imperial court but also the Senate and the supreme courts moved to Constantinople from old Rome along with lots of citizens. Nevertheless, the magnificent and historic remains of the Christian Roman Empire can be seen in some places such as Haghia Sophia, Constantinople’s cathedral for more than a millennium, Basilica Cistern, an underground cavern to store drinking water and St. Esprit Cathedral, a Roman Catholic Church in Istanbul.

Turks
Eventually, in 1453, the Ottoman Turks led by Sultan Mehmet II officially conquered Constantinople and renamed the city like Istanbul. Then it was made the capital city of the Ottoman Empire. Since then, the Turks have been living in Istanbul. Even though it changes every day, the approximate number of Turks living in Istanbul is more than 13 million. Even though they outnumber any ethnic origin, Istanbul city incorporates the features of all ethnic origins throughout its lands. Thanks to this variety, people can experience the breathtaking beauty of cultural richness.
Armenians – Jewish People – Syriacs
After the conquest, Sultan Mehmed brought back Rums, Armenians, Syriacs, Jewish people and Catholic residents who had fled, as well as Jewish, Christian and Muslim people for a mixed population. Therefore today, Istanbul is a host to approximately 19.000 Jewish people. Armenians in Istanbul are not only one of the largest ethnic minorities of Istanbul but also a major part of the Turkish Armenian community. The estimated population of Armenians is up to 70,0 00 in Istanbul city. Besides Armenians, there are 17,000 Syriacs in Istanbul city.

Syrians
Apart from the people who come to Istanbul because of educational, financial, cultural reasons, there are some people who come to Istanbul because of vital issues. Syrians constitute the last community who migrated to Istanbul in mass.
The opposition in Syria that started in 2011 led to the death of hundreds of thousands of people. Unfortunately, the doom of survivors was not brighter because this opposition obliged more than 5 million people to flee. While some refugees tried to reach Europe via the Aegean and Mediterranean seas, most of them took shelter in Turkey.
