 The Banguingui built "kuta" (forts) throughout the Sulu Archipelago.Like their other Sama cousins, they sailed various ships like the "vinta", "salisipan", or "bangka-bangka" throughout the Sulu-Sulawesi region.At the height of the Sulu Sultanate, the Banguingui, along with the Iranun people, formed the bulk of the Sultan's navy, leading coastal raids against settlements in the northern Philippines, as well as the coasts of neighboring Borneo, Sulawesi, and the Maluku Islands.
