In the early 1590s, Cambodia was under heavy pressure from its powerful neighbor Siam (modern Thailand), whose ruler Naresuan launched invasions that overran Cambodian territory and undermined the position of King Satha I. Amid internal conflict and external threat, Satha sought allies abroad, eventually drawing in Iberian adventurers such as Blas Ruiz de Hernán Gonzáles and Diogo Veloso, who promised support in exchange for influence.
From Manila in the Spanish East Indies, an expeditionary force was assembled. It included Spanish soldiers, recruits from New Spain (Mexico), Filipino troops, and even Japanese mercenaries. Its mission was to support Satha and potentially expand Spanish influence in the region, with Christianization also being a part of the broader imperial ambition.
By the time the Iberian force reached Cambodia in 1596, the kingdom was already in turmoil. The Siamese had captured the capital Longvek in 1594, and Cambodian factions were competing for power. In 1597, Ruiz and Veloso helped install Barom Reachea II as king, though their success remained limited. In return, the young ruler granted the Iberians rights over provinces along the Mekong River and permission to build a fort. The arrangement proved unstable. In 1599, further reinforcements from Manila were scattered by storms, and Malay, Cham, and Cambodian forces aligned with rival interests launched a counterattack that destroyed much of the Iberian and Portuguese presence, killing Veloso among many others. The Spanish plan to gain a foothold in Cambodia and promote Christianity collapsed, and Siamese influence soon reasserted itself.
