Nguyễn Phúc Chu

[citation needed] Early in his reign the Champa ruler of Panduranga (in present-day Phan Rang, Ninh Thuận), Po Sot, began a rebellion against the Nguyễn.

Three years later, a Cham aristocrat, Oknha Dat, obtained the help of General A Ban (a somewhat mysterious figure).

The result was the Cham rulers in Panduranga were recognised as Trấn Vương (local lords) for the next 135 years, though they had no authority over Vietnamese living in the area.

In 1714, Nguyễn Phúc Chu sent an army into Cambodia to support Keo Fa who claimed the throne against Prea Srey Thomea (see also the article on the Post-Angkor Period).

[citation needed] In 1720, near the end of his reign, Nguyễn Phúc Chu, took formal control over the last lands of the Champa.
