In the year 1498–99, the Bruneian Empire conducted a series of raids against the natives of the Kingdom of Taytay in Palawan and the island of Mindoro which had been subjugated to the Islamic Bruneian Empire under Sultan Bolkiah. The Muslim conquest reached as far as the Kingdom of Tondo which was supplanted by Brunei's vassal-state the Kingdom of Maynila.[17][18]
