Mandalorians were a predominantly human ethnolinguistic cultural group who originated on the planet Mandalore. Mandalorians had a particularly unique role in galactic history as legendary warriors against the Jedi, and could be commonly found not only on the Mandalorian homeworld and its moon, Concordia, but across Mandalorian Spaceand 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 Mandalorianpolitical faction controlled Mandalore's government, led by DuchessSatine 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 until Clan Saxon was defeated by the Mandalorian clans loyal to Bo-Katan Kryze who later took up the title of Mand'alor soon after.
