Lê Hoàn
In 980, the Song dynasty of China under Emperor Taizong ordered a Chinese army to invade Đại Cồ Việt. Because the young emperor was unable to lead the country to against the invader, the mandarins of the royal court discussed with Empress Dương Vân Nga about enthroning the most trusted general and regent, Lê Hoàn. Most of them voted in the affirmative to this proposal; consequently, the empress dethroned her own son and gave the crown to Lê Hoàn. He accepted the emperorship, establishing a new dynasty named the Early Lê dynasty. Lê Hoàn is often referred to with the posthumous name Lê Đại Hành.
