ALL you need to know about the ancient capital
Hue Vietnam, the former imperial capital, boasts a long-lasting treasure trove of world-renowned ancient wonders, distinctive cultural traits, and delightful traditional cuisine, where visitors can immerse themselves in Vietnam’s illustrious history as if they are traveling back in time.
Hue originally belonged to a prefecture of the Champa Kingdom before the occupation of the Vietnamese. Hue, Vietnam had started its long history as a feudal capital since when it was ruled by the nine Nguyen lords of Inner Realm (Central and Southern Vietnam) from 1687 to 1775. Subsequently, the Tay Son brothers conquered Hue and it remained the administrative capital from 1788 to 1801. After the fall of the Tay Son Dynasty, Emperor Gia Long (Nguyen Anh), a successor of the Nguyen lords, recaptured Hue Imperial capital and unified the Vietnamese monarchy, which paved the way for the reign of the thirteen emperors of the Nguyen dynasty – the last dynasty in Vietnam from 1802 to 1945.
