History

The oldest ruins in Huế belong to the Kingdom of Lâm Ấp, dating back to the 4th century AD. The ruins of its capital, the ancient city of Kandarpapura (lit. 'the city where Śiva burnt Kama'), is now located in Long Tho Hill, three kilometers to the west of the city. Kandarpapura might have only been established during the reign of Kandarpadharma (r. 629–640) and it was named after the king, certainly it may be not the name of the capital of former Lâm Ấp kingdom.

Another Champa ruin in the vicinity, the ancient city of Hoa Chau is dated back to the 9th century.

However, Tay Son rebellions broke out in 1771 and quickly occupied a large area from Quy Nhon to Binh Thuan Province, thereby weakening the authority and power of the Nguyen lords. While the war between Tây Sơn rebellion and Nguyễn lord was being fought, the Trịnh lords sent south a massive army and easily captured Phú Xuân in 1775. After the capture of Phú Xuân, the Trịnh lords' general Hoang Ngu Phuc made a tactical alliance with Tay Son and withdrew almost all troops to Tonkin and left some troops in Phu Xuan. In 1786, Tây Sơn rebellion defeated the Trịnh garrison and occupied Phú Xuân. Under the reign of the emperor Quang Trung, Phú Xuân became the Tây Sơn dynasty capital. In 1802, Nguyen Ánh, a successor of the Nguyen lords, recaptured Phu Xuan and unified the country. Nguyen Anh rebuilt the citadel entirely and made it the Imperial City capital of all of Vietnam.
