The Mandalorian Wars
The Mandalorian Wars was the term given to the sixteen years of conflict between the Mandalorian warrior culture and the Galactic Republic the began with the Battle of Althir. Occurring two decades after the end of the Exar Kun War, the Mandalorian Wars spanned almost two decades themselves, though historians often disagreed on the endpoints of the conflict; the Mandalorians raided star systems in the Outer Rim Territories for over a decade before they actually came into conflict with the Republic Military. Led by Mandalore the Ultimate, who pioneered the Neo-Crusader movement with the help of his lieutenant, Cassus Fett, the Mandalorians conquered systems along the eastern edge of the galaxy. Though their conquests included the near-extinction of the Cathar species, it was not until their assaults on worlds near the planet Taris that they drew the Republic’s attention. After a year of small conflicts known as the False War, the Mandalorians broke through the Republic’s lines and besieged Taris, and then invaded the Republic through three separate corridors in what became known as the Onslaught.
The tide ultimately turned when a group of interventionist Jedi known as the Revanchists, led by the charismatic Revan and his friend Malak, joined the Republic Military in combating the Mandalorians. A tactical genius, Revan won several victories against the Mandalorians and began to reclaim lost territory, prompting Supreme Chancellor Tol Cressa to appoint him Supreme Commander. Driving back the Mandalorians, Revan forced a final showdown with Mandalore the Ultimate at the Battle of Malachor V. Revan personally defeated Mandalore in single combat as the Republic and Mandalorian fleets battled above Malachor V, and the activation of the superweapon known as the Mass Shadow Generator devastated both the planet and the participating fleets.
