Ang Nan
Batom Reachea III was a Cambodian vice king from 1682 to 1689.
Ang Nan was the grandson of vice king Outey. In 1674, with the help of the Ayutthaya Kingdom, Preah Keo II drove him out. Ang Nan fled to Thái Khang, and sought help from Vietnamese Nguyễn lord. The Vietnamese army under Nguyễn Dương Lâm and Nguyễn Đình Phái invaded Cambodia, captured Prey Nokor, then attacked Phnom Penh. Preah Keo II retreated into the forest and Ang Nan was crowned the vice king by the Vietnamese. Ang Nan occupied Prey Nokor, while king Chey Chettha IV occupied Longvek. Both of them paid tribute to Nguyễn lord every year.
However, Ang Nan wanted to overthrow Chey Chettha IV. In 1682, he recruited refugees from Ming China whom had settled in Cambodia with Vietnamese immigrants, resumed fighting against Chey Chettha IV. In response, Kau Kan and Preah Trapeang were ceded to these Chinese adventures. In 1689, with the help of the Nguyễn lord, he made his last attempt to overthrow Chey Chettha IV. He died in Srey Santhor.
