Nguyen Hue, also known as Emperor Quang Trung, born in Bình Định in 1753, died in Phú Xuân on 16 September 1792, is the second emperor of the Tay Son Dynasty of Vietnam, reigning from 1788 until 1792.

He is also one of the most successful military commanders in Vietnam's history.

Nguyen Hue and his brothers, together known as the Tay Son Brothers, are the leaders of the famous Tay Son Rebellion.

As rebels, they conquer Vietnam, overthrowing the imperial Later Lê Dynasty and the two rival feudal houses of the Nguyen in the south and the Trinh in the north.

After several years of constant military campaigning and rule, Nguyen Hue dies at the age of 40, possibly due to a stroke.

Prior to his death, he had made plans to continue his march southwards in order to destroy the army of Nguyen Anh, a surviving heir of the Nguyen Lords.

Nguyen Hue's death leads to the downfall of the Tay Son Dynasty.

His successors are unable to follow the plans he had made for ruling Vietnam.

However, his conquests mark the beginning of approximately a century in which Vietnam is both unified and independent until the Western conquest of Vietnam in 1885.
