In the history of Vietnam, the Tay Son dynasty existed for a relatively short time, from the time when the Tay Son dynasty revolted against the Nguyen royal government in Dang Trong in 1771, to the end in 1801, the Tay Son dynasty existed only 30 years. But it is recorded that this dynasty only really started in 1788, when Nguyen Hue has crowned Emperor in Phu Xuan, to 1801, when the court of Canh Thinh withdrew from here to flee to the North, that is, within 14 years. Although short-lived, this dynasty has left a brilliant page in the history of the nation.

The land of Phu Xuan - Thua Thien Hue has been attached to the Tay Son dynasty since very early when Nguyen Hue liberated Thuan Hoa - Phu Xuan (1786). It was here that the Tay Son uprising developed to its peak under King Quang Trung (1788 - 1792). 
 

Thua Thien Hue and the development of the Tay Son uprising

Grasping a favorable opportunity to defeat Thuan Hoa, on May 25, 1786, the Tay Son army under the leadership of Nguyen Hue set out to Thuan Hoa. On June 20, 1786, the Tay Son army attacked Phu Xuan citadel, the deputy town keeper Hoang Dinh Can was defeated and committed suicide. General of Trinh Pham Ngo Cau bound himself to give his life to be spared but was later put to death in Quy Nhon. Hearing of the defeat in Phu Xuan, the Trinh army who held the garrisons of Dinh Cat (Quang Tri), Dong Hai (Dong Hoi, Quang Binh) all left the garrison to escape. This glorious victory created an important premise for the cause of abolishing the boundary dividing the two regions and unifying the country.

After escaping from the clutches of the Trinh generals, the people of Thuan Hoa began to rebuild their homeland, and joined forces to support the Tay Son uprising, carrying swords and spears to join the army of "cloth armor and red flag" to continue the long march to protect the country. Many documents (writings, artifacts) found on Thua Thien Hue land today such as village logs have declared the number of people participating in the Tay Son uprising. Xuan Hoa village register declared that all the people joined the army, Da Le Thuong village register (Huong Thuy) recorded 255 soldiers and officials of the court out of a total of 295 people...

Thanks to the righteousness and popular consensus, the Tay Son uprising has strongly attracted the participation of the masses, including the very positive response of the people of Thuan Hoa – Phu Xuan.
