According to Expanded Universe sources, Tusken Raiders are named after Fort Tusken, an early Old Republic mining settlement in which all of the settlers were overwhelmed and captured or killed by Tusken Raiders, then referred to as Sand People. The attack probably occurred due to the fort's placement over one of the Raiders' holy wells.
The comic book series Star Wars: Republic explains that exiled Jedi Sharad Hett and his son A'Sharad Hett lived among the Tusken Raiders for many years. Hett was one of the few non-Tuskens to be accepted into their ranks and was even given the title of Warlord. Although A'Sharad Hett believed he was half-Tusken for the better part of his life, during his training on Coruscant he learned that humans and Tusken Raiders were genetically unable to interbreed. This leads him to believe that his mother must have been a human, captured by the Tusken Raiders at a young age and raised as a Tusken. The series Star Wars: Legacy, set some 200 years later, reveals that A'Sharad eventually turned to the dark side of the Force and, as the Sith Lord Darth Krayt, briefly conquered the galaxy.
The Cavefish biker gang from the Lucasarts game Full Throttle were designed to resemble Tusken Raiders in appearance.
