The Mandalorians—known in Mando'a as the Mando'ade, or "Children of Mandalore"—were a nomadic group of clan-based people consisting of members from multiple species and multiple genders, all bound by a common culture.

"We don't have a word for hero. Being prepared to die for your family and friends, or what you hold dear, is a basic requirement for a Mando, so it's not worth a separate word. It's only cowards we had to find a special name for."
―Baltan Carid
