Tusken Raiders, less formally referred to as Sand People or simply as Tuskens, were a culture of nomadic, primitive sentients indigenous to Tatooine, where they were often hostile to local settlers. The term Sand People was given to them due to their existence in the desert, and was in use from at least around 4000 BBY; but the more formal name of Tusken Raiders was acquired much later, due to a period of concerted attacks on the settlement at Fort Tusken in 98-95 BBY. Although this name is often used as a common term for the race, it actually refers only to the participants of the attack on the settlement.
Specialists studying the past of the Tusken Raiders also used the term Ghorfa to denote an earlier sedentary phase of their culture, and lastly Kumumgah, for the earliest stratum of sentient civilization on the planet, believed by some to represent a common ancestry shared by the Ghorfa and the Jawas. In the culture of the Tuskens, to expose any part of the flesh was forbidden and seen as a disgrace. (Source: Wookiepedia)
