The United Clans of the Mandalore or the UCOM, was founded in 72 BBY by Mandalore the Dominant. It emerged as one of the greatest factions of Mandalorians in the Galaxy until 11 BBY when tension within the faction erupted into a violent civil war. The brutal warfare resulted in the fragmenting of the UCOM into many, separate factions. The most prevalent of the fragmented clans were Clan Daedron, Clan Jiu, Clan Zuxo, and Clan Darum.
