The Sabbat Worlds Crusade was an Imperial Crusade fought over the course of more than 23 standard years between 755.M41 and 778.M41 to retake the Sabbat Worlds Sector located at the rimward edge of the Segmentum Pacificus from the heretical Forces of Chaos. This Crusade was one of the largest and most significant Imperial military operations undertaken in recent history and ultimately ended in the reconquest of the sector by the armed forces of the Imperium of Man.
