Lê Hoàn (10 August 941 - 18 March 1005), posthumously title Lê Đại Hành, was a Vietnamese king and the 3rd ruler of Dai Viet kingdom, ruling from 981 to 1005. He first served as the generalissimo commanding a ten-thousand man army of the Dai Viet court under the reign of Đinh Bộ Lĩnh. Following the death of Đinh Bộ Lĩnh in late 979, Lê Hoàn became regent to Đinh Bộ Lĩnh's successor, the six-year-old Đinh Toàn. Lê Hoàn deposed the boy king, married his mother, Queen Duong Van Nga, and in 980 he became the ruler. He commanded the Viet army fended off a northern invasion in 981, then led a seaborne invasion of the southern Champa kingdom in 982.
In early 995, 100 Viet warships sailed onto Yongzhou (Nanning, Guangxi), sacked the town of Ruhong before leaving. In summer, Le Hoan’s local officials from To Mau (modern-day Quang Ninh) led a village force of 5,000 men and sailors who invaded China, plundered Luzhou near Yongzhou, but were defeated by Chinese general Yang Wenjie. In 1004, Le Hoan sent a mission to China led by one of his sons, Prince Lê Minh Đề. Minh Đề was invited for the 1005 Lunar New Year Festival’s feast of the Song court along with emissaries of Champa and Arab. The Song records treated Dai Viet along with Java, Pagan, and the Arabs as equal sovereign states. Outside China and Champa, a Khmer inscription dated 987 records the arrival of Vietnamese merchants in Angkor
