The conflict known as the Battle of Mandalore unfolded in Sundari, which serves as the capital city of the planet Mandalore. This clash occurred amidst the broader Clone Wars and signaled the outbreak of a civil war. The opposing sides consisted of Mandalorians loyal to the rogue Sith Lord Maul, operating covertly, versus those aligned with Lady Bo-Katan Kryze, the sister of the assassinated Duchess Satine Kryze.
While primarily a conflict between these two Mandalorian factions, specifically the Mandalorian super commandos and the Mandalore resistance, the former Sith Master of Maul, Darth Sidious, made an appearance. Sidious ultimately killed Savage Opress and took Maul prisoner. The catalyst for this battle was Obi-Wan's mission to rescue Satine.
