Lê Long ÃÂénh (; , 15 November 98619 November 1009), also known as Lê Ngá»Âa Triá»Âu (), was the last emperor of the Early Lê dynasty of the kingdom of ÃÂại Cá» Viá»Ât, ruling from 1005 to 1009. After killing his predecessor and brother Lê Long Viá»Ât, he took the throne and named his era Cảnh Thụy. His death at the age of 23 led to the fall of the Early Lê dynasty, and power was seized by the Lý dynasty. In some history books, he is portrayed as a self-indulgent and cruel emperor. However, a lot of temples were created where people still worship him, and recently, some historians have proved that some rumours about his ruling style were exaggerated, and possibly fabrications.
Lê Long ÃÂénh, who was also named Lê ChàTrung (), was born on 15 November 986 by the Western calendar. He was the fifth son of Emperor Lê Hoàn, but historians do not note the background of his mother, only information regarding a concubine. He was the half-brother of the duke of Nam Phong (), Lê Long Viá»Ât.
The Complete Annals of ÃÂại Viá»Ât () recorded that in 992 he was granted the title Prince of Khai Minh (, ) and ruled over ÃÂằng county (now Hðng Yên province). In 1004 the crown prince and duke of Kinh Thiên, Lê Long Khâu, died; the emperor made Lê Long Viá»Ât the crown prince of ÃÂại Cá» Viá»Ât and Lê Long ÃÂénh the duke of Khai Minh.
In 1005, Lê Hoàn died in Trðá»Âng Xuân palace. Crown Prince Lê Long Viá»Ât contested the crown with his three brothers: TÃÂch, KÃÂnh, and ÃÂénh. The four princes pitted their armies against each other, plunging the country into civil war. In October 1005, Viá»Ât defeated TÃÂch, forcing him to flee to Champa where he was subsequently killed by locals at the Cá La estuary. The victorious Viá»Ât was proclaimed emperor with the title ('Emperor Trung Tông').
Three days after his ascension, however, Trung Tông was murdered by assassins in Lê Long ÃÂénh's employ. All of his supporters fled except for Lý Công Uẩn, who embraced the body of the emperor and wept. In the winter of 1005, Lê Long ÃÂénh took the throne with the regnal name () and gave his mother the title ().
After news of the death of Emperor Lê Hoàn in China, Song dynasty officials urged the Song emperor Taizong to dispatch forces to invade ÃÂại Cá» Viá»Ât. However, Taizong chose to respect the tributary status that ÃÂại Cá» Viá»Ât had towards the Song Empire, and he left the country alone. Some trading activities occurred between both nations.
In spring 1007, Lê Long ÃÂénh ordered his brother to gift a white pangolin (or white rhinoceros) as a gift to the Song dynasty in exchange for Buddhist sutras to be sent to Vietnam. In the Vietnamese Buddhist records of Zen Buddhist ThÃÂch MáºÂt Thá»Â, in the 14th year of the Ứng Thiên era (1008), Lê Long ÃÂénh sent an envoy to Song to pay tribute and asked for nine classic texts and sutras to take back to Vietnam. The Song emperor approved the request and gave the requested works to the Vietnamese ambassador. The nine classics included I Ching, Classic of Poetry, Book of Documents, Book of Rites, Spring and Autumn Annals, Classic of Filial Piety, Analects, and Mencius. These were the first classics of Chinese civilization to come to Vietnam.
According to the Complete Annals of ÃÂại Viá»Ât, Lê Long ÃÂénh stands out as a brutal and sadistic ruler. His reign was considered as a "reign of terror" at that time.
The Abridged Chronicles of Viet recorded that the emperor was "bloodthirsty". Whenever someone was to be executed, he would order thatch grass to be wrapped around his body and set on fire, leaving him to burn to death. Or he would entertain by ordering the Song Chinese court jester Liêu Thủ Tâm () to slowly mutilate victims using dull swords and axes so that they don't die quickly. When the victims cried out in agony, Thủ Tâm would remark: "This one is not used to death". The emperor was said to have enjoyed this joke. Every time there was a court session, he ordered jesters and performers to sing and talk nonsense to cover up the words of whoever reporting.
After capturing prisoners of war, Long Dénh purportedly ordered to escort them to the riverbank where they were put in cages. When the high tide rose, he would watch them drown slowly. The emperor is said to stab animals such as pigs or cows to death before allowing servants to bring them to the kitchen. At one night, he have cats killed and served to the guests. After eating, the emperor displayed the cats' heads, and all the princes vomited. Another time, the king would put a sugarcane stick on the head of the Supreme Monk Quách Mão, then pretend to accidentally swinging his knife to make a cut on Quách Mão's forehead and laugh it off.
According to historical records, he developed hemorrhoids and often held court while lying down, earning the popular name ( means 'lie' and means 'court'). He was not given a temple name because his successor ended the Early Lê dynasty and started the Lý dynasty.
He held the throne for four years, until 1009, when he died at the age of 23. His son Sạ was a child at the time, under the supervision of an official named ÃÂào Cam Má»Âc (). When Lý Thái Tá» became emperor of the Lý dynasty, all the officials enthroned him without any debate, and the Early Lê dynasty was abolished after only three emperors.
