Castille War

In 1576, the Spanish Governor in Manila was Francisco de Sande. He sent an official mission to neighbouring Brunei to meet Sultan Saiful Rijal. He explained to the Sultan that they wanted to have good relations with Brunei and also asked for permission to spread Christianity in Brunei. At the same time, he demanded an end to Brunei proselytisim of Islam in the Philippines. Sultan Saiful Rijal would not agree to these terms and also expressed his opposition to the evangelization of the Philippines, which he deemed part of Dar al-Islam. In reality, De Sande regarded Brunei as a threat to the Spanish presence in the region, claiming that "the Moros from Borneo preach the doctrine of Mahoma, converting all the Moros of the islands".

Spain declared war in 1578, attacking and capturing Brunei’s capital at the time, Kota Batu. This was achieved as a result in part of the assistance rendered to them by two noblemen, Pengiran Seri Lela and Pengiran Seri Ratna. The former had travelled to Manila to offer Brunei as a tributary of Spain for help to recover the throne usurped by his brother, Saiful Rijal. The Spanish agreed that if they succeeded in conquering Brunei, Pengiran Seri Lela would indeed become the Sultan, while Pengiran Seri Ratna would be the new Bendahara. In March 1578, the Spanish fleet, led by De Sande himself, acting as Capitán-General, started their journey towards Brunei. The expedition consisted of 400 Spaniards, 1,500 Filipino natives and 300 Borneans. The campaign was one of many, which also included action in Mindanao and Sulu.

The Spanish succeeded in invading the capital on 16 April 1578, with the help of Pengiran Seri Lela and Pengiran Seri Ratna. The Sultan Saiful Rijal and Paduka Seri Begawan Sultan Abdul Kahar were forced to flee to Meragang then to Jerudong. In Jerudong, they made plans to chase the conquering army away from Brunei. The Spanish suffered heavy losses due to a cholera or dysentery outbreak. They were so weakened by the illness that they decided to abandon Brunei to return to Manila on 26 June 1578, after just 72 days. Before doing so, they burned the mosque, a high structure with a five-tier roof.

Pengiran Seri Lela died in August–September 1578, probably from the same illness that had afflicted his Spanish allies, although there was suspicion he could have been poisoned by the ruling Sultan. Seri Lela's daughter left with the Spanish and went on to marry a Christian Tagalog, named Agustín de Legazpi de Tondo.

The local Brunei accounts differ greatly from the generally accepted view of events. The Castilian War entering the national conscience as a heroic episode, with the Spaniards being driven out by Bendahara Sakam, supposedly a brother of the ruling Sultan, and a thousand native warriors. This version, nevertheless, is disputed by most historians and considered a folk-hero recollection, probably created decades or centuries after.

Notwithstanding their retreat from Brunei, Spain managed to keep Brunei from gaining a foothold in Luzon. Aside this, a few years later, they were ready to trade again with the Sultanate, as evidenced by a letter from Don Francisco de Tello de Guzmán, Governor General of Manila, dated 1599 imploring for a return of normal relationship.
