Concord Dawn was an arid, sparsely populated world inhabited mainly by farmers. It was located in the Outer Rim, and was known as the homeworld to Clan Aden. The law on Concord Dawn were the Journeyman Protectors. The planet was caught up in the Mandalorian Civil War in 58 BBY.
The world was home to a number of Mandalorians — Concord Dawn was the birthplace of Jango Fett as well as his mentor Jaster Mereel and most members of Clan Aden. Imperial Lieutenant Sheckil was also native to the planet.
Concord Dawn was the home to the Karatos Plague. All inhabitants of Concord Dawn were inoculated against it at birth.
During the New Mandalorian Crusade, Mandalore Cadden Blackthorne targeted Concord Dawn for his campaign to reunite the clans. Kyr Aden organized the Mandalorian mercenaries on the world to fight back, but was ultimately defeated and swore his fealty to the new Mandalore. Late in the Xen'Chi War, Kyr relocated his entire clan to Mandalore.
