Nguyễn Bặc in the context of Đinh dynasty

Nguyễn Bặc (chữ Hán: 阮匐, 924 – 15 October 979), also known with the noble title Định Quốc Công (定國公), was a Vietnamese mandarin and general who served as the Grand Chancellor of Đinh dynasty and was the first chancellor in Vietnamese history. He helped future emperor Đinh Bộ Lĩnh put an end to the troubles of the Anarchy of the 12 Warlords and to establish the short-lived Đinh dynasty. After Đinh Bộ Lĩnh and his chosen successor Đinh Liễn were murdered by a palace official, Đỗ Thích, Nguyễn Bặc captured the murderer and had him executed. He then tried unsuccessfully to organize resistance to Lê Hoàn. According to Nguyễn Phúc tộc thế phả (Nguyễn Phúc clan Family tree book), Nguyễn Bặc was the ancestor of the Nguyễn Phúc clan, followed by founding of the Nguyễn lords by Nguyễn Hoàng in 1558 and Nguyễn dynasty in 1802 under the emperor Gia Long. As a result, he was sometimes considered to be a patriarch of the surname Nguyen, which is the most common amongst all Vietnamese people. Moreover, he was considered as one of the "seven heroes of Giao Châu" (Giao Chỉ province) according to Việt Sử tân biên including: Đinh Bộ Lĩnh, Đinh Liễn, Lê Hoàn, Đinh Điền, Phạm Hạp and Phạm Cự Lượng.
