The New Mandalorians were members of a reformist Mandalorian political movement on Mandalore. The group was formed after a Galactic Republic attack on the Mandalore sector which rendered portions of the planet into inhospitable white-sand deserts.

There, segregated from the warrior clans of the rest of Mandalore's people, the New Mandalorians lived in grand bio-cube cities, taking the domed city of Sundari to be their capital. The New Mandalorians disregarded the ancient Mandalorian warrior code
