Mandalorians were a predominantly Human ethnolinguistic cultural group who originated on the planet Mandalore. In their early years, Mandalorian culture revolved around war, with battles fought being a source of honor and pride in their community. The leader of the Mandalorian people was known as the Mand'alor. Mandalorians had a particularly unique role in galactic history, and could be commonly found not only on their home Mandalore and its moon, Concordia, but across Mandalorian Space and the galaxy at large on worlds such as Kalevala, Krownest, and Concord Dawn. Through their history, Mandalorians were frequently allied with the Sith, and held a certain distrust and dislike for the Jedi Order. However, they would not hesitate to cooperate with them if a partnership between the groups was mutually beneficial. In later years, the Mandalorians moved away from their obsessively war-like and conqueror ways and instead, most of them became bounty hunters and mercenaries, selling their skills to various individuals and factions in the galaxy. After the rise of the Galactic Empire, Mandalore fell under the Imperial rule, while some of the other Mandalorian worlds such as Concord Dawn were free from Imperial rule. Mandalorians wore very distinctive battle armor strongly associated with Mandalore, including helmets that covered the entirety of their faces, and would provide inspiration for Clone Troopers.
The New Mandalorians was an pacifist government that controlled the Mandalore system in the Outer Rim that placed great importance on virtues pacifism, neutrality, and nonviolence rather than military-strength. During a point in the final decades of the Galactic Republic, a Mandalorian civil war was fought between competing ideals in Mandalorian society such as warrior clans and insurgents that wished to see a return to their old warrior past and the New Mandalorians led by Satine Kryze of a House Kryze. At the end of the civil war, the Duchess of Mandalore Satine Kryze ruled their planet while the warrior-clans were exiled to Concordia. Although the New Mandalorians rejected the old ways, the capital city Sundari displayed murals detailing their exploits during their wars with the Jedi. The Pacifist government was led by the Duchess Satine until its dissolution following the coup in the same time as the end of the clone Wars when their pacifist ideal were eventually opposed by Death Watch, who sought to return the Mandalorian people to the proud martial ways of their ancestors. Backed by the criminal-forces of the Shadow Collective syndicate, the Death Watch's coup proved to be too much for these New Mandalorians. This government fell in the face of Death Watch's rise, while the Mandalorian revanchists eventually put an end to this Mandalorian-faction along with the ultimate demise of a Duchess Satine Kryze.
