The Cambodian–Dutch War (Dutch: Cambodjaans-Nederlandse Oorlog; Khmer: សង្គ្រាមកម្ពុជា-ហូឡង់) from 1643–1644 was a conflict sparked by a coup which brought a new Cambodian King to the throne who converted to Islam with the help of Malay traders resident in the country. The new King initiated a massacre of Dutch East India Company employees and subsequently defeated the Dutch forces sent to extract retribution from the Cambodians.
