Mandalore the Conqueror was the leader of the Mandalorian Clans for nearly half of a century. He became Mandalore after the death of Mandalore the Deceitful and was the leader of the clans during the Great Territorial War. Despite originally siding with the Third Sith Empire and the Chiss House of EbonClaw, Mandalore realized that they would simply betray him so he aided the Galactic Republic and the Jedi Order in taking Coruscant back from the hands of the Sith. He was later one of the causes in the Great Rim Lines War, at the end of which he executed Ussej Padric Bac II. Five years later, he was a major player in the United Pirate Crusades.
