The Castilian War, also called the Spanish Expedition to Borneo, was a conflict between the Spanish Empire and several Muslim states in Southeast Asia, including the Sultanates of Brunei, Sulu, and Maguindanao. It is also considered as part of the Ottoman-Habsburg War, and that war is the beginning of relations between the Ottoman state and Brunei in 1560 to 1578.

Spanish arrival in the Philippines

The Spanish settlements soon began to encroach on the aspirations that Brunei had in the Philippines. Between 1485 and 1521, Sultan Bolkiah's influence has reached the Manila Bay region, as recorded by the Spaniards during their encounter with Prince Ache in 1521, who was Bolkiah's grandson. The Islamic presence in the region was also strengthened by the arrival of traders and missionaries from the areas of Malaysia and Indonesia.^[4]

Despite Bruneian influence, Spanish colonization continued in the archipelago. In 1571, Miguel López launched an expedition from his capital in Cebu to conquer and Christianize the city of Manila, which became the new capital for the Spanish administration. Furthermore, the Visayan peoples of Panay and Cebu (who historically fought against Brunei's allies of Sulu and Maynila) aligned themselves with the Spaniards against Brunei. In 1576, Governor-General Francisco de Sande sent a request to meet with Sultan Saiful Rijal, expressing a desire for good relations with Brunei. However, In 1573, the Governor-General De Sande demanded both permission to proselytize Christianity in the region, and an end to Brunei's proselytizing of Islam. De Sande regarded Brunei as a threat to Spanish presence and religious efforts in the region, stating that "the Moros from Borneo preach the doctrine of Mohammed, converting all the Moros of the islands".^[5]^[6]

War

Governor-General Francisco de Sande officially declared war against Brunei in 1578, and began preparations for an expedition to Borneo. De Sande assumed the title of Capitán-General and assembled a fleet carrying 200 Spaniards, 200 Mexicans, 1,500 native Filipinos (Luzones), and 300 Borneans.^[7] The ethnic composition of the Spanish force was shown to be diverse by later documents that stated the infantry was made up of mestizos, mulattoes, and "Indians" (from Peru and Mexico), led by Spanish officers who had previously fought with native Filipinos in military campaigns across Southeast Asia.^[8] The expedition began their journey in March, and the Bruneian campaign was one of several that was undertaken at the time, including action in Mindanao and Sulu.^[9]^[10]

In addition to native Malay warriors, Bruneian forces were supported by the Ottomans who had been sent in several expeditions to the nearby Sultanate of Aceh and were composed of Turks, Egyptians, Swahilis, Somalis, Sindhis, Gujaratis, and Malabars.^[11] These expeditionary forces spread to nearby Sultanates and taught local mujahideen new fighting tactics and techniques to forge cannons.^[12]

Aftermath

While the Spanish were unable to immediately subjugate Brunei, they did manage to prevent it from regaining a foothold in Luzon.^[13] Relations between the two nations later improved and trade resumed, as evidenced by a 1599 letter from Governor-General Francisco de Tello de Guzmán in which he asked for a return to a normal relationship.^[14]

As a result of the conflict, Brunei ceased to be an empire at sea. It gradually set aside its policies of territorial expansion and developed into a city-state, surviving to the modern day as the oldest continuously Islamic political entity.^[15]
