The Mandalorians

Early History
Mandalorians have been one of the few influential warrior cultures the Known Galaxy has ever seen. A warrior culture based on the world of Mandalore, this civilisation is ruled by a Mandalore, a rank equivalent to a king or queen.

Formed from the now extinct species The Taung, a multi-alien warrior culture formed and by the time of 2000 BBY were actively involved with the galaxy due to numerous wars with the Galactic Republic and Jedi Order.

The Clone Wars
Despite having a mandalorian as the genetic template of the Republic's Clone Army, the Mandalorians kept away from the conflict to deal with their own internal issues concerning their philosophies and so two factions formed within the society, the New Mandalorians, a pacifist group who refused to return to Mandalore's warrior culture past and Deathwatch, a group eager to return the culture's bloody past and reclaim it's position as a dominant superpower in the galaxy
