Đinh Liễn
Đinh Liễn or Đinh Khuông Liễn, was the eldest son of emperor Đinh Bộ Lĩnh, the founding emperor of Đinh dynasty.
Liễn was granted the title Nam Việt vương after his father ascended the throne. Liễn was sent to Song China to pay tribute in 973, and was granted the title Grand Preceptor of Inspection, Jiedushi of Tĩnh Hải quân and Governor of the Protectorate General to Pacify the South by Song Taizu. In 975, his title was promoted to "Prince of Giao Chỉ" by Song court. Liễn was regarded as the ruler of Vietnam by Song China, though his father was the de facto ruler.
In 978, Đinh Hạng Lang was consecrated as the crown prince, which made Liễn dissatisfied. Liễn assassinated Hạng Lang in spring 979. In October, Liễn and his father were killed by a eunuch named Đỗ Thích while they were sleeping in the palace courtyard.
