Brunei versus Spain - The Castillian War

BRUNEI attained its golden age under the reign of its fifth ruler, Sultan Bolkiah, known as Nakhoda Ragam. During his reign, the Brunei Empire spread not just over the whole island of Borneo but as far as Sulu and Saludang (Luzon) in present-day Philippines. He not only increased Brunei's trade but was also able to help spread Islam.

Brunei's Golden Age continued even after the death of Sultan Bolkiah in 1524. Sultan Abdul Kahar was also able to increased Brunei's territories which included the whole of Borneo, Palawan, Sulu, Balayan, Mindoro, Bonbon, Balabak, Balambangan, Bangi, Mantanai and Luzon. With the Brunei traders, Islam spread far including to the southern Philippines islands and Brunei was recognised as a centre of Islamic propagation.
