[1][2] It was not until the period of Đông Ngô state, a small administrative unit called Khoái-châu (快州, "Khoái canton") that actually appeared in documents.

Howeved, in April 1297, the Trần Dynasty merged Khoái Lộ in Thiên-trường phủ-lộ (天長府路, "Thiên Trường prefecture and garrison").

However, in 1426, King Lê Lợi personally abolished to set up a temporary administrative unit called Nam-đạo (南道, "South garrison").

By 1490, Emperor Hồng Đức re-changed Thiên Trường Thừa Tuyên to Sơn-nam xứ (山南處, "Sơn Nam domain").

In June 1527, Emperor Minh Đức merged Sơn Nam Xứ into Dương-kinh (陽京), the vice capital of Mạc Dynasty's Annam.

In January 1741, under the rule of Emperor Cảnh Hưng, name Khoái-châu phủ (快州府, "Khoái Châu prefecture") had appeared at the first time, but it was a bad type of pun in the eyes of contemporary scholars.

On October 24, 2024, the National Assembly Standing Committee of Vietnam issued Resolution 1248/NQ-UBTVQH15 on the arrangement of the commune-level administrative unit of Hưng Yên province in the period of 2023–2025, which takes effect from December 1, 2024.

Đông Tảo commune in Khoái Châu rural district is an administrative unit with a history recorded up to a thousand years.

In particular, the area of Khoái Châu rural district is only from average to very low, even many places are still lower than the sea level and are in the process of being fostered by sediment.
