鄭松
Nguyễn Phúc Nguyên was the sixth son of Nguyễn Hoàng. Upon the death of his father, Nguyễn Phúc Nguyên took over the rule of the southern provinces of Vietnam. He continued his father's policy of refusing to submit to the authority of the court in Hanoi, dominated at this time by his cousin, Trịnh Tùng. Unlike his father he did not take the title Vuong but instead called himself "Nhon Quoc-Cong" (roughly Duke of the Southern Provinces).
