Black Templars - Ages of Apostasy and Redemption (M35-M40): Barbarus Incursion (831.M35) - The Black Templars took part in an unknown campaign remembered only by its name -- the Barbarus Incursion. Following this campaign all records pertaining to it were sealed and declared Inconcessus (forbidden).Wars of Apostasy (Terran Crusade) (378.M36) - The Wars of Apostasy, known to the Black Templars as the Terran Crusade, were a series of battles fought against the forces of the apostate High Lord Goge Vandire during the Age of Apostasy in the 36th Millennium. During this tumultuous period, the Black Templars had concerned themselves little with the affairs of the Imperium, but when crusade fleets returned to the Segmentum Solar and discovered that their Chapter keeps had been destroyed by orbital bombardments carried out by the Ecclesiarchy's Frateris Templar, the full extent of Vandire's treachery became apparent. Enraged, in 378.M36 the Black Templars' High Marshal Sigenandus declared a crusade to be launched against Vandire on Terra. The Black Templars, together with their progenitor Chapter the Imperial Fists as well as the Soul Drinkers, the zealous Fire Hawks and elements of the Martian Tech-Guard, took the fight to Terra itself and laid siege to Vandire's Ecclesiarchal Palace. The crusade ended with the death of Vandire at the hands of one of his former bodyguards -- Alicia Dominica, the founder and patron saint of the Adepta Sororitas.The Second Purging of Lastrati (543.M36) - The Second Purging of Lastrati occurred in 543.M36, as a part of the Athalor Crusade, under the command of Marshal Gervhart of the Black Templars. Lastrati had become a place of pilgrimage, and for centuries, the faithful had come to bear witness to such spectacles as the Hill of Heretics and the Plain of Purity. Marshal Gervhart and the Black Templars of the Athalor Crusade had come to Lastrati to take heart from the planet's potent displays of faith from the past, but were horrified by what they found. The population had turned to barbaric blood rituals and human sacrifices in search of genetic perfection. The Black Templars realised that the rituals of the people of Lastrati had too much in common with the heretical Chaos Cult worship of the Ruinous Powers. Marshal Gervhart ordered the planet cleansed of its degenerate inhabitants before continuing the crusade. After four standard years of fighting, the warriors of Marshal Gervhart forced the remaining forces of Lastrati back onto the Plain of Purity. There they made their last stand at the Hill of Heretics, before their army was utterly destroyed by the Black Templars.Benedictine War (Unknown Date.M37) - The Benedictine War was a War of Faith unleashed by the Ecclesiarchy. Endeavouring to forget the corruption of the previous millennium, the Adeptus Ministorum sought penance by conquering the xenos-filled Benedictine Sub-sector. The Black Templars sent their entire Chapter to fight alongside five orders of Sisters of Battle and massed armies of faith. Several Aeldari worlds were captured, and in the ensuing conflicts, two Black Templars High Marshals were slain in swift succession. The Ecclesiarch himself declared an end to the war, claiming that they had achieved enough in the Emperor's name and recalling his armies. New High Marshal Constantine continued the crusade regardless, and the Black Templars alone successfully cleansed the remaining worlds of xenos.Arkron Crusade (Unknown Date.M38) - The Arkron Crusade was a crusade launched by the Black Templars in the closing years of the 38th Millennium. Directed into the Ghoul Stars, it numbered hundreds of battle-brothers.Aegisine Crusade (Unknown Date.M39) - The Aegisine Crusade was a crusade initiated by the Black Templars in the 39th Millennium. Directed at the rebel drift worlds of the Mangdragora Sector, it was a long and bitter war. The Black Templars employed the "Iron Cyclone" Dreadnought drop strike assault pattern, launching their Drop Pods from Strike Cruisers in low orbit of Aegisine. Despite taking withering ground fire, the maneuver proved decisive and ended a conflict that had bogged Imperial forces down for solar decades.The Angevin Crusade (322.M39) - The Black Templars participated in the Angevin Crusade, which led to the conquest of the Calixis Sector for the Imperium, fighting alongside elements from their fellow Astartes Chapters the Tigers Argent, the Sons of Medusa and the Charnel Guard.The Jerulas Crusade (645.M39) - The Jerulas Crusade was an Imperial Crusade launched by the Black Templars and led by their High Marshal Ludoldus. Jerulas was a long-isolated star system, only rediscovered by the Imperium in the late 39th Millennium on the outer fringes of the galaxy. Attempts were made to integrate its worlds into the Imperium, but the system had long been prosperous and independent, and scorned Imperial interference. The first missionaries from the Missionaria Galaxia were slaughtered, but when a second group of Imperial priests came to the system they brought the Black Templars with them. Under the direct command of High Marshal Ludoldus, the Templars fought the forces of the rebel worlds with great success until they came to the well defended hive cities of Jerulas itself. Each attempt to capture the hive cities was fought back with great losses and it seemed like the Templars would be unable to force their way into the sprawling arcologies. But the answer was found by the Black Templars Artificer Simagus, who discovered the means to develop the now legendary Land Raider Crusader. Armed to smash through enemy defences and disgorge squads of Astartes right into the thick of the fighting, the Crusader was the perfect weapon for breaching the defences of the Jerulas hives.The Donian Crusade (985.M39) - The Donian Crusade was carried out by the Black Templars to combat the swelling Ork population sweeping through the Donian Sector and surrounding Wilderness Space in the southern sectors of the Segmentum Pacificus.
