History
During the reign of Emperor Tự Đức until the French occupation of Hà Tiên (1847-1867), Ab Biên was the name of the only prefecture (An Biên Prefecture) belonging to Hà Tiên province, comprising three districts: Hà Châu, Kiên Giang, and Long Xuyên.
In 1876, the during the French colonial period, the An Biên prefecture, which had existed since the Nguyễn Dynasty, was abolished. In 1936 it was made an administrative district of Rạch Giá province, with its headquarters at Thứ Ba market.
In 1956, the Republic of Vietnam renamed An Biên district to Kiên An district, belonging to the newly established Kiên Giang province, with the district seat remaining in Thứ Ba. This remained true after the end of the Vietnam War in 1976.
On 1 July 2025, as part of the 2025 Vietnamese administrative reforms, 63 provinces and cities were merged down to 34 first-level subdivisions, and rural districts were eliminated entirely. As a result, the district of An Biên was dissolved. Its former province of Kiên Giang was also dissolved, and the former land areas of An Biên and Kiên Giang are now within the province of An Giang.
