They originally had an independent state known as the Sulu Sultanate, which once exercised sovereignty over the present day provinces of Basilan, Palawan, Sulu, Tawi-Tawi, and the eastern part of the Malaysian state of Sabah (formerly North Borneo).
Tausūgs are experienced sailors and are known for their colorful boats or vintas. They are also superb warriors and craftsmen. They are known for the Pangalay dance (also known as Daling-Daling in Sabah), in which female dancers wear artificial elongated fingernails made from brass or silver known as janggay, and perform motions based on the Vidhyadhari (Bahasa Sūg: Bidadali) of pre-Islamic Buddhist legend.
Prior to modern times, the Tausūg people were under the Sultanate of Sulu. The system is a patrilineal system, consisting of the title of Sultan as the sole sovereign of the Sultanate (in Tausūg language: Lupah Sug, literally: "Land of the Current"), followed by various Maharajah and Rajah-titled subdivisional princes. Further down the line are the numerous Panglima or local chiefs, similar in function to the Philippine political post of the Baranggay Kapitan in the Baranggay system.
Of significance are the Sarip (Shariff) and their wives, Sharifah, who are descendents of Arabic royalty. They are respected as religious leaders, though some may take up administrative posts.
