The Tausug Moros lived in the Sulu archipelago, which was traditionally ruled by the Sulu Sultanate. The Maguindanaon Moros lived on Mindanao, which was traditionally ruled by the Maguindanao Sultanate. The Maranao Moros lived around Lake Lanao, which was traditionally ruled by the Confederation of Sultanates in Lanao. They were invaded by the Americans during the Moro Rebellion and annexed into the Philippines. Among the anti-Japanese resistance the Tausug leader was Sulu Sultan Jainal Abirin II and the Chinese-Maguindanaon leader Datu Gumbay Pia. A few of the Maranao leaders were Datu Busran Kalaw, Salipada Pendatun, Sultan Alonto, and Sultan Dimaporo. Salipada Pendatun's brother-in-law, Major Datu Udtug, also fought against the Japanese, and in Cotabato, the focal area of the anti-Japanese resistance was Papalungan.
