How a 17th-century Cambodian King humiliated the powerful Dutch East India Company
In 1642, a newly converted Muslim King of Cambodia launched a brutal campaign against the Dutch East India Company. By orchestrating a massacre of Dutch diplomats and seizing their ships, he inflicted a crushing defeat that halted European influence in the region for two centuries, leaving the Dutch empire reeling.
The conflict originated from escalating trade tensions. In 1635, the Dutch detained Cambodian ships in the Sea of Makassar, sparking a diplomatic standoff. Relations worsened in 1636 when the Dutch ship Noordwijk arrived in Cambodia; local authorities confiscated its cargo of copper. When Henry Hagenaar arrived in 1637 to mediate, he further alienated the Cambodian court by seizing a Portuguese vessel within Cambodian waters, ignoring local law.
The situation turned violent in 1642 when Prince Ponhea Chan seized the throne, becoming King Reameathiptei I. Influenced by Malay merchants, he converted to Islam, adopting the name Ibrahim. In 1643, he ambushed a Dutch diplomatic mission led by Pieter van Regemortes in the capital, Oudong. The massacre claimed the lives of the ambassador and dozens of Dutch personnel, while others were enslaved. The Dutch attempted a naval retaliation on the Mekong River in 1644, but they suffered a decisive defeat, losing 156 men and several warships.
Following the failure of the 1644 expedition, Dutch leadership in Batavia debated further action. Governor-General Van Diemen sought an alliance with the King of Siam, but his death in 1645 left his successor, Cornelis van der Lijn, wary of the costs and risks. The Dutch eventually pivoted to diplomacy, securing the release of 29 enslaved workers in exchange for peace, which was formally signed in 1656. The Dutch presence in Cambodia ultimately withered, with all trading posts abandoned by the 1670s after the King was ousted by Vietnamese forces.
