The Apostate War (Tausug; Parrang Murtad, Malay: ڤراڠ مرتد‎, romanized: Perang Murtad) also called the Bruneian-Sulu War was a conflict between the Sulu Sultanate and the Bruneian Empire. Brunei also fought Spain briefly as well

This war was also the first time Brunei ever used flintlock muskets, as they began acquiring them in the late 17th century and early 18th century
