Following the Mandalorian Wars, Clan Jendri emerged as a distinct Mandalorian clan. The Mandalorian Wars concluded with the defeat of Mandalore the Ultimate, the Mandalorian leader, at Malachor V. This defeat was at the hands of Revan, a Jedi Knight, who subsequently took Mandalore's Mask. In the aftermath, many Mandalorian clans embarked on a search to recover the missing mask. By 3954 BBY, Clan Jendri's quest had brought them to Rekkiad, an icy planet located in the Outer Rim Territories of the galaxy. Upon arrival, Clan Jendri established their dominion over the Twin Spears mountain, a region they diligently patrolled utilizing four Basilisk war droids. In that same year, Clan Ordo, another Mandalorian clan, entered Jendri's territory, also seeking Mandalore's Mask. A skirmish ensued between Clan Jendri and Clan Ordo for regional control. Despite Jendri's numerical advantage of nearly two to one, Clan Ordo emerged victorious. Consequently, Clan Jendri relinquished the territory to Clan Ordo's control.
The first appearance of Clan Jendri in the Star Wars expanded universe was in The Old Republic: Revan. This novel was penned in 2011 by the author Drew Karpyshyn.
