== History ==
It would be more appropriate to start the historical development of Gölcük with the region that the [[Ancient Greece|Ancient Greeks]] and [[Roman Empire|Romans]] called [[Bithynia]], which also includes [[İzmit|Izmit]] and its surroundings. It is thought that Gölcük was known as ''Diolkides'' (''Diolkídis'' in antiquity).<ref>{{cite web|url=http://imperium.ahlfeldt.se/places/31382.html|title=About: Diolkides, opposite Zeytin Burnu|access-date=2013-08-01|author=Johan Åhlfeldt|language=en}}</ref>
The first step for Gölcük to become a [[garrison]] city was taken in 1927. The technical need that emerged with the decision to repair the battleship Yavuz, which was damaged in 1925, led to the establishment of a military shipyard in Gölcük. A pool was built in the same year. The [[Germans]] built barracks and repaired Yavuz.{{cn|date=October 2024}} Later, these facilities established by the Germans were purchased and the core of the shipyard was established. Parallel to the development of the [[Turkish Naval Forces]], although the fundamental studies were started in 1938,{{cn|date=October 2024}} II. [[World War II]] prevented these works and the real development of Gölcük Shipyard has been realized since 1950. Gölcük is truly a city founded after the Republic. Except for Halidere, Ulaşlı and Yazlık villages of Gölcük, 21 villages were administered by the Bahçecik Sub-district Directorate of Izmit sanjak.{{cn|date=October 2024}}
After the proclamation of the [[Turkish National Movement|Republic]], the town center and the Gendarmerie were established in the village of İhsaniye in 1930.{{cn|date=October 2024}} The population of the city of Gölcük started to increase rapidly with the workers and their families coming from the Istanbul shipyards to work in the workshops established for the repair of the battleship Yavuz. In the meantime, Gölcük district was established with the law numbered 3012, which was adopted on June 9, 1936 and entered into force on June 15, 1936.{{cn|date=October 2024}} Due to the absence of a building suitable for government offices in Gölcük in the accident organization, it started to work temporarily in the rented buildings in the town of Değirmendere. The Government Mansion, whose construction was completed in a short time, was passed in 1938 and the State organization was settled in Gölcük.{{cn|date=October 2024}}
With the establishment of the boiler, the Subdistrict Directorate was abolished from İhsaniye, leaving only the Gendarmerie Organization.{{cn|date=October 2024}} In the expropriations made with the Special Expropriation Law No. 3887 enacted in 1942, the Government Organization was transferred to Değirmendere in February 1944, with a decision taken by the Provincial General Assembly, since the Government Mansion remained within the expropriation area. After staying in Değirmendere for 10 years, the government moved back to Gölcük in accordance with the law no. 6322 enacted on March 4, 1954.{{cn|date=October 2024}} Due to the government's arrival in Gölcük, the District and Population Organization and the Police Department were established in Değirmendere. This number has increased to 23 by taking Halidere and Ulaşlı villages of Gölcük, which has 21 villages, from Karamürsel. However, with Değirmendere becoming a township, the number of villages decreased to 22. When Damlar District of Saraylı village became a detached village in 1959, the number of villages increased to 23 again.{{cn|date=October 2024}}
The Municipality Organization was established in İhsaniye village with the decision of the Council of Ministers dated 06.09.1966 and numbered 4636. Today Gölcük district, one (centre) Gölcük, others; It has 6 towns and 23 villages, namely Değirmendere, İhsaniye, Halıdere, Ulaşlı, Hisareyn, Yazlık.
