Lê Uy M?c (ch? Hán: ???; 5 May 1488 – 1 December 1509), also called Lê Tu?n (??), was the eighth emperor of the later Lê dynasty of Vietnam.
He was the second son of Emperor Lê Hi?n Tông and the elder half-brother of his direct predecessor, Emperor Lê Túc Tông.
Lê Uy M?c was portrayed in Ð?i Vi?t's historical annals as an arrogant and ruthless monarch.
His reign oversaw the beginning of the decline of the Ð?i Vi?t empire, having been prosperous and powerful during the able reigns of Lê Thánh Tông, Lê Hi?n Tông and Lê Túc Tông.
Annalists during the Revival Lê dynasty recorded him as having killed many people including his grandmother and two of his ministers, as well as many imperial princes.
He also wasted his energy in excessive drinking and sexual activities.
It was alleged that some Ming ambassadors, having examined the emperor Lê Uy M?c's aggressive physical appearance, labelled him as Evil King (Qu? vuong, ??).In 1504, Uy M?c arrested his cousin Lê Oanh, son of Hi?n Tông's younger brother Lê Tân.
Oanh eventually escaped southwards to Thanh Hóa, the homeland of the imperial house.
Here, Oanh organized a rebellion against the government.
After hard fighting, rebel forces approached the imperial capital Thang Long and killed the emperor, ending a short reign of only 4 years.
Lê Oanh was enthroned as Emperor Lê Tuong D?c, who later turned to be another unpopular monarch.
