Constantinople: However, the death of Emperor Constantine I, in 337 AD, was translated into Constantinople (Greek: Konνσταντινοstantπολι ş, K adınstantinoúpolis, Latinized: Constantinopolis), which means “the city of Constantine”. 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).

In 1453, after the conquest of the Ottoman Empire by the Ottoman Sultan Fatih Sultan Mehmed, Constantinople remained the most common name used in the West. October 29, 1923 years after the establishment of the Republic of Turkey, even if the name is almost Constantinople during the first 7 years of the Republic has continued to be used by Westerners.

The name Istanbul has been in Arabic sources since the 10th century and in Turkish sources since the 11th century. In addition, the name Istanbul, even before the conquest of 1453 in Turkish, especially used for the city among the Turkish people.

In his early period documents in the Ottoman Empire [18] the name Istanbul was mentioned in Ottoman Turkish, (استان, a-sitan or i-stan), and in Arabic i-stan means “land of beauties”. In the last period documents (استانبول, a-stan-bol or i-stan-bul) as passed.

Although Istanbul was not an official name during the Ottoman period, it was frequently used in official documents. In addition, officially the Istanbul military for the central army commander of the Ottoman Army and the highest civilian judge of Istanbul were officially used as the master of Istanbul. This adjective has become a prestigious one and has been used for the non-informal and well-educated people of Istanbul.

October 29, 1923 years after the establishment of the Republic of Turkey, even in Constantinople and abroad throughout almost the first seven years of the Republic of Constantinople names continue to be used by Westerners was adapted.

However, the name of the city was officially changed with the Turkish Postal Service Law on March 28, 1930 and was renamed as Istanbul. The name Constantinople (and Constantinople) was completely repealed. In addition, the Turkish authorities demanded the use of the name Istanbul officially as the only name of the city in their own language. After the official and international name of the city, the name of Constantinople was banned in the letters or other correspondence and international areas. For example, in letters sent from abroad to Istanbul, these letters were sent back to “Constantinople” (even if Istanbul was written).

The history of Istanbul can be divided into five major periods: the 
period 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 time of King Lygos, an Acropolis was established in Sarayburnu and today’s Topkapı Palace. The Greeks from Megara founded a colony here in 685 BC, and Byzantion was founded in 667 BC when King Byzas reigned. When the Roman Empire was dominated by the city, the name of the city was named Augusta Antonina by his son, Septimius Severus, for a short time. Then, during the reign of Emperor Constantine I, the city was declared the capital of the Roman Empire. In the meantime, the name of the city was changed to Nova Roma and it was converted to Constantinople in 337 with the death of Emperor Constantine I.

Byzantine Empire Period: This period covered between 324 and 1453 years. After the conquest of Constantinople and the capital of the Roman Empire, the city also became the center of the east of Rome. The Roman population increased significantly during this period, including the immigration of Roman nobles. In this period; The city has expanded with a new architectural structure. In addition to a 100,000-person hippodrome (Sultanahmet Square), harbors and water facilities were built.

In the period of Constantinus, the city called Nova Roma; On 11 May 330 the city became Constantinople. Constantine, who founded the Hagia Sophia, the world’s largest cathedral in 360; thus he changed the religion of the Roman Empire to Christianity. The first rupture with the west of the pagan Roman religion began in this period. Although; Although the Byzantine Empire begins with the death of Theodosius I; The Byzantine Empire always regarded itself as a Byzantine Emperor for his respect for the coming of Constantinople of Christianity; Until his fall in 1453, his 10 emperors had become Constantine. The role of Istanbul in this period was highly strategic; There was a door between Europe and Asia. It was a center of trade, culture and diplomacy. In this period, the name of the city was “Poli” (city).

After the collapse of Western Rome in 476; The majority of the Romans in the Western Roman Empire migrated here, and the Byzantine Empire was the capital of Istanbul. After the plague epidemic in 543, which caused the death of half of the population; the city was rebuilt during the reign of Emperor Justinian.

But; The most devastating one among the attacks was in 1204. By the Crusaders; In the 4th Crusade, the city seized in 1204 was looted; the vast majority of the people fled from the city; it turned into a city in poor and debris. The reason for this is that the Latin people who grew up in Western Rome; There are differences and discrepancies between Catholic Christian understanding and Orthodox Christian faith in Byzantium. After this period, in 1261, from the Palailogos Dynasty; Michael VIII Palaeologus regained the city and ended the Latin era.

After this period, gradually shrinking Byzantine; The Ottoman Empire began to be besieged after 1391; Finally, on May 29, 1453, he was promoted by the Ottoman Empire. The conquest of Istanbul symbolizes the end of the Middle Ages in World history.

Byzantine’s last emperor Constantine was defending Istanbul very well before the conquest. Even the burning of the Gregorian region made the sea voyages difficult. The strength of the cities made it difficult to enter the city by 70-80%. But Fatih Sultan Mehmet opened a new era by succeeding …

The period of the Ottoman Empire: This period covered between 1453 and 1923. 29 May 1453; After the siege of Sultan Mehmet the Conqueror, which lasted for 53 days; Istanbul was the 3rd and last capital of the Ottoman Empire.

[33] 50 years after the conquest; Also known as the “Little Apocalypse” in Istanbul, which has become one of the largest cities in the world; 14 September 1509 After the Istanbul Earthquake (it is claimed to be 8); Thousands of buildings collapsed with 45-day aftershocks and many people lost their lives.

In 1510; Sultan II. Bayezid; He re-established the city with the work of 80,000 people. The vast majority of the existing works remained from this period. During the reign of Suleiman the Magnificent, where Sinan built mosques and other buildings; importance was given to architecture and art. During the Tulip Period; Grand Vizier Nevşehirli Damat İbrahim Pasha from 1718 onwards; He founded the fire brigade, opened the first printing house and established factories. After the Tanzimat Edict, which was proclaimed on November 3, 1839, there were many innovations in the period when the process of westernization accelerated.

Bridge over the Golden Horn; Istanbul, which became a modern city with the establishment of tunnels, railways, maritime transport in the city, municipal organizations and hospitals in Karaköy, once again suffered great damage together with the earthquake in 1894. At the end of World War I, on November 13, 1918, was occupied by the Entente states’ navy. Istanbul’s capital of 2500 years ended on 29 October 1923.

Art:The city, many times the hands changed and worn in the city, the Roman Empire, more than the structure of the remaining structure. The column was formed by stacking 8 pillars and a pedestal on top of each other, each with a weight of 3 tons and a diameter of 3 meters. Another structure remaining from this period to the present is the Bozdoğan Arch. The construction of the city’s water reserve system began during the reign of Emperor Hadrian. During the reign of Constantinople during the reign of Constantinople and the growth of the city, it was necessary to expand the system to meet the needs of the rapidly growing population. Kemer, the water between Kağıthane and the Sea of ​​Marmara between the hills of the hills and Thrace ‘ from the hilly areas of the city to the city’s wide water supply system meets the water needs and channels took place at the last point. At that time, the water was stored in more than a hundred underground cisterns, such as the three open and overcrowded Cistern basins with a total capacity of more than 1 million cubic meters. 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. It was used as a patriarchate in 1454 after the conquest of Istanbul. In 1590 it was converted into a mosque as a memory of the conquest with the conquest of Georgia and Azerbaijan in the Iranian wars. The Chora Church, one of the most important buildings, was built in 534 by Saint Theodius during the reign of the Roman Emperor Justinian. In the 11th century, it was rebuilt by the mother-in-law Maria Doukaina of Alexios I. The monastery, which had been devastated during the Latin Empire period of 1204-1261, was restored by Theodoros Metokhites in the 14th century. External narthex and parekklesion were added to the structure during this period.

Ottoman Empire:Art in the Ottoman Empire is far ahead in architecture. Numerous works have been made during the imperial period. The buildings are simple and useful as well as dignified and majestic. The magnificent palace type came from the West in the 19th century. However, the mosques in the name of Allah and Tekkeler is completely abidevî. 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. Sinan lived for a century and spent the

City Panari: Istanbul has 39 districts. 25 of these districts are located on the European side and 14 on the Asian side. The districts of Istanbul are divided into three main regions: 
Fatih and Eminönü, the historical peninsula of Old Istanbul (the district of Eminönü was connected to the district of Fatih with a law in 2008. Today, the peninsula constitutes the district of Fatih). Haliç is located on the northern shores of this region. It extends to the Western Walls in the West. The southern border forms the Sea of ​​Marmara Sea. In the east there is the entrance of the Bosphorus.

Beyoğlu and Beşiktaş districts in the north of the Golden Horn are of great importance in terms of history. The palace of the last Ottoman sultans is located in Dolmabahçe Palace Kabataş. Old districts such as Ortaköy and Bebek follow each other along the shores of the Bosphorus. On the two sides of the city there are luxury flats along the Bosphorus.

Uskudar (ancient Chrysopolis) and Kadikoy (ancient Chalcedon) districts in ancient times as a city changed over time and became the district of Istanbul. It is the oldest districts of Istanbul on the Asian side. Nowadays, it has great importance in terms of many modern residential areas and business areas. It hosts one third of the city’s population.

As it goes west and north from the historical districts of Istanbul, there is a great differentiation. The highest skyscrapers and office buildings are on the European side, especially in Levent, Mecidiyeköy and Maslak. The rapid growth of the city in the 20th century led to the beginning of a great migration from east to west. Thus, the squattering in the city has gained a great speed. These buildings, which are made as treasure or private land as a leak, are made in a short time and in low quality. Ankara between Turkey’s largest city, and it is widely held in Izmir. Squatters are largely caused by distorted urbanization.

The second half of the century, especially on the Anatolian side of the sea near the construction of summer houses and luxury pavilions has been accelerated. Bağdat Street in Kadıköy district has many shopping centers and restaurants with its width and length. This has contributed positively to the development of the region. The biggest factor in population growth in recent years is the migration from Anatolia. Today, 66% of the people of Istanbul live on the European side.

Management: Kadir Topbas, the mayor of Istanbul, is currently working. The governor of the city is Hüseyin Avni Mutlu.
