The Indomitus Crusade is a Crusade that was launched by the resurrected Primarch Roboute Guilliman, after he declared himself Lord Commander of the Imperium's armies, during the Thirteenth Black Crusade. The main aim of the Crusade is one of reconquest, as Guilliman intends to liberate those Imperium worlds embattled by the forces of Chaos following the creation of the Great Rift; which has divided his Father's Empire in half.
Guilliman's forces consist of troops from over a dozen Space Marine Chapters led by the Imperial Fists. These are joined by Imperial Guard, Mechanicum, Custodes, Sisters of Battle, Imperial Navy, a small contingent of Sisters of Silence, and the newly created Primaris Space Marines.
The Indomitus Crusade continued for around 100 years, and by the Plague Wars of early M42 was in its closing phases. Following the Battle of Raukos Guilliman held a great Triumph and announced the dispersion of the Crusade throughout the Imperium.
