Chey Chestha III

Chey Chettha IV (1656–1725), born Ang Sor, was a Cambodian king for several periods in Cambodia's history (r. 1675–1695, 1696–1700, 1701–1702, 1705–1706).

Life He was the second son of Barom Reachea V and also a younger brother of Kaev Hua II. Vietnamese army attacked Phnom Penh, the king Kaev Hua II fled into forest. Ang Sor surrendered to Vietnamese. He was crowned the Cambodian king by Vietnamese, while Ang Nan (Padumaraja IV) was crowned the vice king (uparaja). Chey Chettha IV occupied Longvek, Padumaraja IV occupied Prey Nokor (Saigon). Both of them paid tribute to Vietnamese Nguyễn lord.

In 1688, Dương Ngạn Địch, a Chinese adventurer and also a general of Nguyễn lord, was murdered by Hoàng Tiến (黃進). Hoàng Tiến occupied Mỹ Tho and revolted against Nguyễn lord. Hoàng Tiến also attacked Cambodia. Using this excuse, Chey Chettha IV started to building fortifications and did not pay tribute to Nguyễn lord. In the same year the rebellion was put down, Chey Chettha had to pay tribute like before.
