Culture and history info
Modern-day Vĩnh Long was part of Long Hồ dinh (barrack, 營) established by the Nguyễn lords in 1732, comprising the provinces of Bến Tre, Trà Vinh, and parts of Cần Thơ.
The area saw some of the heaviest fighting between the Tây Sơn brothers and the Nguyễn lords in the late 18th century; in 1784 Nguyễn Huệ defeated Siamese forces aiding Nguyễn Ánh at the Mang Thít River.
In 1951, the Southern Resistance Administrative Committee of the Democratic Republic of Vietnam merged Vĩnh Long and Trà Vinh provinces into Vĩnh Trà Province. Vinh Tra existed until 1954 (however, as North Vietnam never administered the area for a significant period of time, this arrangement was not enforced). In 1957, the South Vietnam formed Vĩnh Long Province, consisting of six districts: Châu Thành, Chợ Lách (now part of Bến Tre Province), Tam Bình, Bình Minh, Sa Đéc, and Lấp Vò. In 1961, Cái Nhum District was split from Chợ Lách. Đức Tôn District and Đức Thành District were added in 1962, but joined the newly formed Sa Đéc Province in 1966. As of 1975, the province had seven districts: Châu Thành, Chợ Lách, Tam Bình, Bình Minh, Minh Đức, Trà Ôn, and Vũng Liêm.
After the fall of South Vietnam, the Socialist Republic of Vietnam merged Vĩnh Long with Trà Vinh Province, forming Cửu Long Province in 1976. In 1991, Cửu Long was again split into Vĩnh Long and Trà Vinh. At the time of the split, Vĩnh Long Province consisted of one city (Vĩnh Long) and five districts: Long Hồ, Vũng Liêm, Bình Minh, Tam Bình, and Trà Ôn.
In 1992, Mang Thít District was re-split from Long Hồ District. In 2007, Bình Tân District was created.
