Concurrent with the spread of Islam in the Philippine archipelago, was the rise of the Lucoes who were the people of Luzon. They rose to prominence by establishing overseas communities all across South and Southeast Asia as well as maintaining relations with East Asia, participating in trading ventures, navigation expeditions and military campaigns in Burma, Japan, Brunei, Malacca, East Timor and Sri Lanka where they were employed as traders and mercenaries. One prominent Luções was Regimo de Raja, who was a spice magnate and a Temenggung (Jawi: تمڠݢوڠ) (Governor and Chief General) in Portuguese Malacca. He was also the head of an international armada which traded and protected commerce between the Indian Ocean, the Strait of Malacca, the South China Sea, and the medieval maritime principalities of the Philippines.
