Sietch Tabr was a major Fremen sietch on the planet Arrakis. Its most famous native-Fremen leader was Naib Stilgar. Sietch Tabr was the Fremen community first encountered by Paul and Jessica Atreides after their escape from Harkonnen assassination attempts following the fall of House Atreides on Arrakis. As a result, it became their adopted home, and the foundation of the Arrakis Revolt; the resistance movement that eventually took control of Arrakis, and launched Paul's galactic Jihad.
