Khúc clan
The Khúc family or Khúc clan was a succession of native leaders who ruled over Tĩnh Hải quân during the late Tang dynasty until the Five Dynasties period.
The Chinese Tang dynasty took control of the region of Jiaozhi in 621 from the preceding Sui dynasty. Later, the Tang dynasty established 12 provinces and 59 districts under the Protectorate of Annan. Effective control exercised by the Tang dynasty lasted until the 10th century, when Khúc Thừa Dụ took over as jiedushi in 905. By 906 an autonomous region in Vietnam was established under the Khúc clan in Tống Bình, paving the way for total Vietnamese independence from China under Đinh Bộ Lĩnh.
