Sultanate of Sulu
The Sultanate of Sulu (Tausug: Kasultanan sin Sūg; Central Sama: Kasultanan Sūg or Kasultanan Sūk; Malay: Kesultanan Suluk; Filipino: Kasultanan ng Sulu or Sultanato ng Sulu) was a Sunni Muslim Tausūg state that ruled the Sulu Archipelago, coastal areas of Zamboanga City, and certain portions of Palawan in today's Philippines, alongside parts of present-day Sabah and North Kalimantan in north-eastern Borneo. The sultanate was founded either on 17 November 1405 or 1457 by Johore-born explorer and Sunni religious scholar Sharif ul-Hashim.
