The Twenty-Third Pius Dea Crusade, a religious military campaign, was initiated by the Pius Dea-dominated Galactic Republic and took place in 11,198 BBY; it is classified as a crusade. During this time, the Republic deployed troops from Ord Masterra to confront Bothawui, the planet inhabited by the enigmatic Bothans, and also sent forces from Ord Dycoll to engage the combative Lanniks residing on Lannik.
The inaugural depiction of the Twenty-Third Pius Dea Crusade was within the pages of The Essential Guide to Warfare, a reference book published in 2012, specifically on a map showcasing various crusades.
