Khúc clan

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 (near modern-day Hanoi), paving the way for total Vietnamese independence from China under Đinh Bộ Lĩnh.

The Tang took control of the northern Vietnamese region of Jiaozhi (Giao Chỉ; roughly corresponding to the area of the modern Red River Delta).

This time China legitimate ruler was the Later Liang, which acknowledged Khuc Hao, but gave title An Nam Tiết độ sứ to another mandarin in Guangzhou, to make Vietnamese remember Chinese territory claims.

Hao had handled several reforms, dividing his land to administrative districts lom phu, chiao, diap, xa.

Although the Khúc did not declare themselves kings or emperors like many of other breakaway states during the Five Dynasties and Ten Kingdoms period, they had established more power for local rule than ever before.
