白藤江
The Battle of Bạch Đằng River was the first significant of many victories throughout the centuries at this famous river. Ngô Quyền then ascended to the throne and took the name "Ngô Vương" (King Ngô) or "Tiền Ngô Vương". He moved the capital back to Cổ Loa. He reigned for only five years, until 944, when he died of illness at age 47. A short reign for an ambitious ruler set the stage for future campaigns for independence. Nevertheless, Ngô Vương ushered in a new Viet era of continuous independence and political autonomy. Due to the Ngô dynasty's failure to control chieftains and Ngô Quyền's failure to gain Chinese acknowledgement of his legitimacy as a ruler, it was little more than a protectorate of the Song dynasty.
