Ramathipadi I
Ramathipadi I, also known as Ponhea Chan, Cau Bana Cand or Sultan Ibrahim, was a Cambodian king, reigning from 1642 to 1658.
Ramathipadi I was a son of Chey Chettha II. With the help of Muslim merchants from Malaya, he murdered Ang Non I in 1642, and ascended the throne. He converted to Islam and changed his name to Sultan Ibrahim. He started to drive out the Dutch East India Company, in 1643, the Cambodian–Dutch War broke out.
However, most Cambodians were Buddhist. Nguyễn Phúc Ngọc Vạn, a consort of his father, wanted to overthrow him, and sought help from Vietnamese Nguyễn lord. In 1658, a Vietnamese army invaded Cambodia, deposed him, and imprisoned him in Quảng Bình. He died in the next year, probably killed by Vietnamese or died of disease.
Chan's three sons took refuge in Siam.
