HISTORY OF KADIKÖY
The historical core composing the beginning of settlement in Kadıköy is within the area created by Haydarpaşa Bay and Moda Point. Kadıköy that remains in the urban area and that is built-up today, has become a residential area in the 19th century with the district and neighborhoods extending to Bostancı.
It can be said that the the first human settlements around Istanbul were in BC 5000 - 3000. The first hand axes belonging to the Paleolithic were found in Içerenköy on the Asian side. The most important prehistoric residential are on the Anatolian side and maybe around Istanbul is the Fikirtepe culture. Fikirtepe is the oldest known Neolithic culture known in Istanbul.
It is known that around BC 1000, there was a trading colony called Harhadon in various sources in Fikirtepe established by the Phoenicians. Kuşdili River was in estuary form in this period and the coastal line was more inside between Fikirtepe and Hasanpaşa compared to today. Then, a second settlement area was created under the name of Khalkedonia (Copper Country) between Moda Point and Yoğurtçu across the first settlement. Khalkedonia (Kalkedon) becomes famous with the Temple of Apollo during this period. Haydarpasa Prairie is used for horse races by the people of Khalkedonia.
Byzantines who laid the foundation of the city of Byzantium by settling in Sarayburnu in 658 B.C. were fascinated by the beauty of the region and they named Kadıköy as the "Land of the Blind" by describing the people settling on the opposite side (Kadıköy) blind as they chose to live on the opposite side instead of this beautiful location, and. For this reason, it has been called by that name in various sources.
Khalkedonia underwent various sieges in the coming centuries. Between 1352 and 1353, the vicinity of Khalkedonia mostly came under the rule of the Ottomans. After the conquest of Istanbul, Fatih Sultan Mehmet gave Khalkedonia to first Istanbul Qadi, 13th Celalzade Hızır Bey, who was the grandson of daughter of the famous Nasreddin Hodja. It is said that the name of the settlement was changed to Kadıköy after this incident.
During the Ottoman period; the vicinity of Kadıköy like the Roman and the Byzantine periods was a favorite summer and recreation resort demanded by the senior managers. Besides, it continued to be a significant agricultural production area. Haydarpaşa, Kuşdili Stream (Kurbağalıdere), Acıbadem and Koşuyolu towards Çamlıca slopes and Fenerbahçe were the outstanding meadow and recreation areas. There were mansions, summer palaces and gardens of the Sultan and senior managers and villages in the inner parts located in a wide area extending to Bostancı. Although the basic characteristics of Kadıköy and its vicinity were formed by seasonal settlements, the first half of the 19th century was a period when the effects of the military activities were felt intensely in parallel to the status of the empire collapsing.
In 1869, Kadıköy was registered to Üsküdar District which used to be a bigger and significant settlement of the time. Kadıköy was made a county in 1930 after being registered to Üsküdar for a long time.
Istanbul and Kadıköy were saved from enemy invasion on October 6, 1923 under the leadership of Great Leader Atatürk.
Kadıköy which had long been registered to Üsküdar became a county on March 23, 1930. On this date, Kadıköy has two sub-districts called Kızıltoprak and Erenköy. Along with the Republican regime, Kadıköy obtained the opportunity to benefit from several modern urban services. These were the tramcar that were founded as a corporation in 1927 and started its first routes between Üsküdar and Kısıklı in 1928 with electricity in 1929.
In the following years, the population between Kızıltoprak and Bostancı increased by two and a half times within a decade with the implementation of the zoning development plan. In the past years, business life in Istanbul was developed further on the European side. Transportation was provided from Kadıköy to settlement areas like Moda, Üsküdar and Bostancı with ships landing to Kadıköy Pier after work and for this reason; Kadıköy with its Piers and Haydarpaşa became a passageway in the following years.
The importance of seaway decreased with the opening of the Bosphorus Bridge in 1970 and as a result, traffic was built down for being directed to the bridge. By the acceleration of migration in 1980s, Kadıköy emerged as a favourite settlement area with the establishment of Metropolitan Municipality with its new development plans. New development plans, development amnesties, title allocation certificates granted respectively of this period caused building density in the city and decrease in social reinforcement areas. After the earthquake in 1999; the necessity of renewal in the buildings and the concept of urban transformation suggested as a solution to this became threat risk as a source of unearned income to specific class.
