The Macharian Heresy was an event in early M41 in Segmentum Pacificus after the death of Lord Solar Macharius, commander of the Macharian Crusade.[1]


After the death of Macharius, the rivalry between his seven Army Group Generals erupted into a civil war throughout the newly-conquered territories. Eventually the swath of territory conquered by Macharius splintered into warring miniature empires, each ruled over by one Macharius' old Generals, who abandoned their oaths of loyalty to the Imperium and opposed not only each other but also the authority of the Adeptus Terra. In addition, Space Marine Chapters that took part in the Crusade came to blows over and petty disputes, such as the Doom Warriors and Inceptors.[2b]

The Dark Angels played a major role during the unrest, suppressing civil wars and uncovering corrupt Alpha Legion affiliated cults over three decades. The Dark Angels also followed the unmistakable signs of Cypher's presence in the unrest.[4]

Known Battles during the Macharian Heresy


It took a seventy year-long Crusade under Warmaster Solon[3] consisting of one hundred Space Marine Chapters to finally put an end to the Heresy. The majority of the worlds that were under the rule of Macharius' old warlords were pacified and re-incorporated into the Imperium.[1]

The cause and nature of the Macharian Heresy are very similar to the events following the death of Alexander the Great, the historical figure who Macharius is based upon.
