Mandalore was a planet located in the Outer Rim Territories. It was the homeworld of the Mandalorians, a fearsome warrior people who fought the Jedi and raided their temple during the fall of the Old Republic. Wearing distinctive armor that was often made from Beskar, they were feared throughout the galaxy, and had political influence over two thousand other star systems.

Years of war left the planet inhospitable, forcing the Mandalorians to live within domed cities. A pacifist regime came to power at the end of these wars, led by Duchess Satine Kryze, while those who refused to give up their warrior ways were exiled to the moon Concordia. During the Clone Wars, the New Mandalorians were overthrown by the renegade Sith Lord Maul's Shadow Collective, though the Galactic Empire would rule the planet after the war's end.
