ÃÂinh Bá» Lénh (924âÂÂ979; ), real name allegedly ÃÂinh Hoàn (), was the founding emperor of the short-lived ÃÂinh dynasty of Vietnam, after unifying the country. He was a significant figure in the establishment of Vietnamese independence and political unity in the 10th century. He unified Vietnam by defeating rebellious warlords and became the emperor of Vietnam. Upon his ascension, he renamed the country ÃÂại Cá» Viá»Ât. ÃÂinh Bá» Lénh was also known as ÃÂinh Tiên Hoàng (; literally "the Former ÃÂinh Emperor").
ÃÂinh Bá» Lénh was born in 924 in Hoa Lð (south of the Red River Delta, in what is today Ninh Bình Province). Growing up in a local village during the disintegration of the Chinese Tang dynasty that had dominated Vietnam for centuries, ÃÂinh Bá» Lénh became a local military leader at a very young age. From this turbulent era, the first independent Vietnamese polity emerged when the warlord Ngô Quyá»Ân defeated the Southern Han's forces in the First Battle of the Bạch ÃÂằng River in 938. However, the Ngô dynasty was weak and unable to effectively unify Vietnam. Faced with the domestic anarchy produced by the competition of twelve feudal warlords for control of the country, as well as the external threat represented by Southern Han, which regarded itself as the heir to the ancient kingdom of Nan Yue that had encompassed not only southern China but also the Bac Bo region of northern Vietnam, ÃÂinh Bá» Lénh sought a strategy to politically unify the Vietnamese. Upon the death of the last Ngô king in 965, he seized power and founded a new kingdom the capital of which was in his home district of Hoa Lð. To establish his legitimacy in relation to the previous dynasty, he married a woman of the Ngô family.
In the first years of his reign, ÃÂinh Bá» Lénh was especially careful to avoid antagonizing Southern Han. In 968, however, he took the provocative step of adopting the title of Emperor (Hoàng ÃÂế) and thereby declaring his independence from Chinese overlordship. He founded the ÃÂinh dynasty and called his kingdom ÃÂại Cá» Viá»Ât. His outlook changed, however, when the powerful Song dynasty annexed Southern Han in 971. In 972, ÃÂinh Bá» Lénh ingratiated himself with the Song by sending a tribute mission to demonstrate his fealty to the Chinese Emperor. Emperor Taizu of Song subsequently recognized the Viet ruler as Giao Chá» QuáºÂn Vðáng (King of Giao Chi), a title which expressed a theoretical relationship of vassalage in submission to the empire. Well aware of Song's military might, and eager to safeguard the independence of his country, ÃÂinh Bá» Lénh obtained a non-aggression agreement in exchange for tributes payable to the Chinese court every three years.
In addition to managing relations with China, ÃÂinh Bá» Lénh energetically reformed the administration and the armed forces of Vietnam in order to strengthen the foundations of the new state. He established a royal court and a hierarchy of civil and military servants. ÃÂinh Bá» Lénh also instituted a rigorous justice system in which treason was punishable by being cooked in a vat of boiling oil or by being fed to a caged tiger, so as to provide a deterrent to all who threatened the new order in the kingdom.
However, ÃÂinh Bá» Lénh's reign did not last long. In 979, a palace official, inspired by a dream, killed both ÃÂinh Bá» Lénh and his eldest son ÃÂinh Liá» n while they were sleeping in the palace courtyard. The killer was quickly apprehended and executed by general Nguyá» n Bặc. Bá» Lénh was succeeded by his six-year-old surviving son Dinh Phe De.
The Song dynasty wanted to take advantage of the turbulent situation in ÃÂại Cá» Viá»Ât in order to reestablish Chinese control over the country, and sent an army to invade Vietnam. In this crisis, Lê Hoàn, the commander-in-chief of ÃÂinh Bá» Lénh's army, stepped into the power vacuum, dethroned the child emperor, eliminated his opponents at court, and entered into illicit relations with the Empress Dowager Dðáng Vân Nga. Lê Hoàn defeated the Song invasion, proclaimed himself Emperor, and founded the Early Lê dynasty. He continued to call the country "ÃÂại Cá» Viá»Ât."
