According to Decision No. 759/QD-TTg dated April 14, 2025 approving the Project on arranging and reorganizing administrative units (ADUs), Thai Binh province will merge with Hung Yen province, named Hung Yen.
According to the Electronic Information Portal of the Department of Culture, Sports and Tourism of Thai Binh province, in the early centuries of the Common era and over the next 5 centuries, Thai Binh was the last land in the south of Chu Dien district - Giao Chi district.
By the 6th century, most of the northern and northwestern land of Thai Binh belonged to Vu Binh district; the remaining land belonged to Ninh Hai district.
During the feudal period of autonomy in 938, Thai Binh land belonged to Chau Dang (including land belonging to the two provinces of Hung Yen and Thai Binh).
During the reign of Tien Le (king Le Ngoa Trieu 1005 - 1009), Chau Dang was known as the emperor of Thai Binh.
During the Ly Dynasty (11th century), Thai Binh province became the province of Thai Binh, consisting of 4 districts of Thuy Anh, Quynh Coi, Dong Quan, Phu Duc.
In the 12th and 13th centuries under the Tran Dynasty, Thai Binh belonged to the land of the two provinces of Long Hung and Thien Truong. Later, Thien Truong Street was separated into two new streets, Kien Xuong and An Tiem. During the Tay Son period, Thai Binh belonged to Tran Son Nam Ha, changed to Thai Ninh province.
During the Nguyen Dynasty (19th century), the Thai Ninh province was restored to its former name, the Thai Binh province. Under the reign of King Gia Long, Minh Menh, Tu Duc, Dong Khanh, the Thai Binh government had many changes in administrative units such as: Chan Dinh district became Truc Dinh district, and Tien Hai district...
By March 21, 1890, Thai Binh province was established, including Thanh Quan, Thuy Anh, Dong Quan, Truc Dinh, Thu Tri, Vu Tien, Tien Hai, Phu Duc, Quynh Coi, Than Khe districts.
In the 6th year of Thanh Thai (1894), Hung Nhan and Duyen Ha districts of Hung Yen were merged back into Thai Binh.
Thai Binh is now an independent province with 3 governments: Tien Hung, Thai Ninh, Kien Xuong.
In the book "Notice sur la province de Thai Binh" by the French scholar (1935) it is written: "When the province was established, in 1890, the province was located in the capital of Kien Xuong, on the banks of the Tra Ly River".
After the August Revolution, in 1946 the Provincial People's Council decided to abolish the general unit and change the government to a district. Thai Binh province is divided into 12 districts, 1 town with 829 communes and villages.
On June 17, 1969, According to Decision No. 93-CP on the merger and adjustment of the boundaries of the districts: Quynh Coi and Phu Duc into Quynh Phu district; Hung Nhan and Duyen Ha into Hung Ha district; Dong Quan and Tien Hung into Dong Hung district; Vu Tien and Thu Tri into Vu Thu district. At the same time, some communes of Vu Tien were merged into Kien Xuong, some communes of Kien Xuong were merged into Tien Hai.
In 1982 and 1986, the Council of Ministers decided to merge a number of communes in Vu Thu and expand the administrative boundaries of Thai Binh town. Since then, Thai Binh has maintained 8 units including Thai Binh city and Dong Hung, Hung Ha, Kien Xuong, Thai Thuy, Tien Hai, Vu Thu and Quynh Phu districts.
Thai Binh is located in the Red River Delta, with an area of nearly 1,600km2 and a population of over 1.86 million people. The province is surrounded by 3 major rivers including the Red River, Luoc River and Hoa River. To the east of Thai Binh province is a coastline of over 50km long, located in the Gulf of Tonkin.
