Godae (ancient) Period :
When the kingdoms of Goguryeo, Baekje, and Shilla were still enemies, the Gimpo region was a major arena of conflict among them. The region appeared in history as ‘Gimpo’ in the 63rd year of the reign of King Jangsu of Goguryeo, or 475AD. In the first year of King Gyeongduk’s reign, after unifying the three nations, Shilla reorganized into 9 states and 5 districts. The Gimpo peninsula belonging to Han Ju was divided into Gimpo Hyeon (Gimpo, Gochon, and Geomdan regions), Bujin Hyeon (Tongjin and Walgot regions), Donseong Hyeon (Haseong region), Suseong Hyeon (Yangchon and Daegot regions), and Gongam Hyeon (Seoul’s Gangseo region). These four Hyeons became JangeGun’s Yeonghyeon (present day Bucheon) while Gongam Hyeon became Yuljin Gun’s Yeonhyeon (present day Siheung).
During the reign of Goyreo’s King Seonjong, Gimpo was a part of Gwanaedo (present day Gyeonggi and Hwanghae regions) and in the ninth year of King Hyeonjong’s reign (1018), it became part of Suju (Bupyeong). In the second year of King Myeongjong’s reign (1182), Gimpo made separate and appointed Gammu, and in the first year of King Shinjong’s reign (1198), Uhtae was appointed Hyeon Ryeong (a government official) and later buried in the region.
Joseon Dynasty :
In the Joseon Period, in August of the14th year of King Taejong’s reign, the region merged with Yangcheon Hyeon and was renamed Geumyang Hyeon. It was then separated again in October of the same year, and Yangcheon was incorporated into Geumcheon (present day Shigheung). Gimpo was then incorporated into Bupyeong, and the Gimpo name disappeared. In July of the 16th year of the Taejong’s reign, the name Gimpo was restored and Gimpo Hyeon was created.
In the tenth year of King Injo’s reign, or 1632AD, Jangreung was enshrined and Gimpo Hyeon was elevated to Gun. During a reorganization in the 32nd year of King Gojong’s reign, Gimpo became a Gun of Incheon Bu, ruled by the fourth Gunsu, or national magistrate in following year.
Pyeonhoihap Hyeon, previosuly located in the Tongjin and Walgot regions, was part of Jangje Gun, passed on to Bunjin Hyeon during a reorganization in the 16th year of King Gyeondeok’s reign, and then to Tongjin Hyeon during the Goryeo Dynasty. It was then merged with the regions of Donseong and Suahn in the third year of King Gongyang’s reign (1391AD) and had Gammu and Hyeonmu government officials appointed during the Joseon Dynasty.
In the 20th year of King Sukjong’s reign (1694AD), it was elevated to Tongjin Bu, and became Tongjin Gun during a reorganization in the 32nd year of King Gojong’s reign. In the 33rd year of the same king’s reign, it became a Gun ruled by the third Gunsu.
The old Dongjahol Hyeon and Suihhol Hyeon were renamed Dongseon Hyeon and Suseong Hyeon (both Yeonghyeon of Jangje Gun) in the 16th year of King Gyeongdeok’s reign. Suseong Hyeon became Sunan Hyeon during the early period of the Goryeo Dynasty and merged with Tongjin Hyeon in the third year of King Gongyang’s reign, they both then disappeared from history.
Jechapaui Hyeon, the old town of Yangcheon was renamed Gongan Hyeon in the 16th year of King Gyeondeok’s reign and became Yeonghyeon of Yuljin Gun, then a part of Suju in the 9th year of King Hyeonjon’s reign (1018). It was then restored to Yangcheon in the second year of King Chungseon’s reign, and had a Hyeonryeong government official. In the 14th year of King Taejong’s reign in the early Joseon Dynasty it was called Geumyang Hyeon and merged with Gimpo, but was separated again in October of the same year. It was restored to status as a Hyeon later, in the 16th year of the same king’s reign, and has a Hyeonryeong appointed. When the 23 districts of Korea were reorganized into 13 regions in the 32nd year of King Gojong’s reign, it became a Gun and part of Incheon district.
Modern times :
During the nationwide reorganization of administrative districts in March 1914, Gimpo, Tongjin, and Yangcheon Gun were integrated into ‘Gimpo Gun’. Before integration, Gunnae Myeon, Seokhan Myeon, and Gohyeonnae Myeon were part of Gimpo Gun, but were changed to Gunnae Myeon; Geomdan Myeon, Masan Myeon, and Nojang Myeon were changed to Geomdan Myeon; and Imchon Myeon, and Gorantae Myeon were changed to Gochon Myeon.
