Mandalorians were a predominantly human ethnolinguistic cultural group who originated on the planet Mandalore. Mandalorians had a particularly unique role in galactic history, and could be commonly found not only on the Mandalorian homeworld and its moon, Concordia, but across Mandalorian Space and the galaxy at large on worlds such as Kalevala, Krownest, and Concord Dawn. Mandalore had a largely martial history, but by the time of the Clone Wars the pacifist and reformist New Mandalorian political faction controlled Mandalore’s government, led by Duchess Satine Kryze. This led to internal conflict with other Mandalorian groups like Death Watch, who wanted to maintain the warrior ways of their Mandalorian heritage.

After the rise of the Galactic Empire, the Mandalore system came under the rule of the Empire with Gar Saxon as their Viceroy, while other Mandalorian worlds such as Concord Dawn were free from Imperial rule.
