Fourth Pius Dea Crusade

The Fourth Pius Dea Crusade was a religious crusade orchestrated by the Pius Dea cult against the Hutts. In 11,920 BBY, the Pius Dea-controlled Galactic Republic launched yet another invasion of Hutt Space, playing off of Republic citizens' fear of the Hutts. Moving along the Pabol Hutta, the Republic Military began to attack planets in the northern region of Hutt Space. Klatooine, Kossimur, Delacta, Sy Myrth, and Boonta were among the planets attacked by the Republic.
