Four thousand years ago, the Mandalore system was home to a group of fierce masked warrior clans led by a mysterious warlord called Mandalore. The clans, made up of deadly but honorable crusaders, rode semi- intelligent Basilisk war droids, boasted cutting-edge weaponry, and were considered to be the best fighters in the entire galaxy. The mask and title of "Mandalore" belonged to no single individual, but were traditionally passed down from one warrior to the next in the event of their leader's death. During the Sith War, the Mandalorians conquered the Kuar system and struck at the neighboring Teta system, forcing the Tetan leader Ulic Qel-Droma to battle Mandalore in single combat. Mandalore was defeated, and he swore his armies' allegiance to Qel-Droma and the Krath forces. The warlord was made Qel-Droma's war commander, and his clans won many victories for their new leader. At the close of the Sith War, however, Mandalore's armies were defeated in their attempt to capture the planet Onderon. Mandalore and his surviving warriors were forced to flee to the Dxun moon, where Mandalore was killed by a pair of the moon's deadly beasts and a new warrior donned his mask and assumed his title.

Millennia later, the warlike Mandalore people exterminated the Ithullan race, several hundred years before the Battle of Yavin. During the Clone Wars, a group of warriors from the system were defeated by the Jedi Knights. The notorious bounty hunter Boba Fett wears an armored suit similar to those worn by these Mandalore warriors, and his alternate ship Slave II is based on a Mandalorian police ship design. Imperial dungeon ships were originally designed by the Mandalorians, and were introduced during the Jedi purge to contain dangerous force users. Mandalorian battle harnesses are designed to be operated by R2 units, and Freedon Nadd's tomb on Dxun was constructed from Mandalorian iron.
