 Dating Code – Events 

 Unspecified Date.M30 - Creation of the Space Marine Legions
 * The Emperor forges his greatest weapons - genetically engineering the superhuman Primarchs. Then, from their gene-seed, the 20 First Founding Space Marine Legions. - [6]

 Unspecified Date.M30 - Birth of the Astronomicon
 * The Emperor creates the great psychic beacon that allows Navigators to steer within the Warp and travel great disances. Originally powered solely by the Emperor, that duty is eventually shifted to a great choir of 10,000 psykers instead, heralding the birth of the organisation that would become the Adeptus Astronomica. - [6]

9th Century, M30
 Dating Code – Events 

 800.M30 - The Great Crusade
 * The Emperor emerges from the anarchy of sundered Terra and leads the campaign to reunite Mankind. The Great Crusade is spearheaded by the newly formed Space Marine Legions, who are armed by the recently allied factories of Mars. Battles unnumbered are fought and the Space Marines, supported by the new Imperial Army, prove unstoppable. Aliens and Warp cratures are driven back, planets are reclaimed and the missing Primarchs are found. The Emperor preaches three great truths in his reconquest of the galaxy: genetic corruption must be sought out and eradicated; psykers are to be rooted out, kept in control and handed over to Imperial agents for evaluation; and destructive aliens are to be rendered powerless. - [6]
 * As the Prmiarchs take control of their Legions, the Great Crusade separates, moving in many directions and reaching far across the galaxy. The Emperor returns to Terra, heaving Horus, foremost amongst the Primarchs, to finish off the great drives of human expansion. It is these deeds and countless battles that create the Imperium of Man. - [6]

 Unspecified Date.M31 - The Horus Heresy
 * The Emperor's most trusted servant, the Warmaster Horus, turns traitor. With half of the Space Maine Legions, four Titan Legions and an untold number of formations from the Imperial Army, Horus makes for Terra, aiming to take the Emperor's Palace as ruler of Mankind. It is a bitter civil war; across space and upon many planets, brother fights brother. Immortalised by many legends the Battle Of Terra and Siege of the Imperial Palace mark the epic finale of the Heresy, with countless heroic actions and notorious deeds. In the end, Horus is slain, but not before the Emperor is mortally wounded, forcing him to retire for evermore to the life-sustaining Golden Throne. - [6]

 Unspecified Date.M31 - The Scouring
 * This is a campaign of vengeance fought against the heretic traitors still found across the galaxy. Loyalist forces, led by the Ultramarines and Space Wolves Legions, drive back those traitors who survived Horus' fall. The corrupted forces find refuge within the swirling Eye of Terror. This time period also marks the grim realisation of just how many planets were lured into helping the traitors. Some are corrupted, others merely mislead of beguiled. Guilt and recrimination henceforth become ride in the new Imperium of Man. - [6]

 Unspecified Date.M31 - Second Founding
 * In the midst of the Scouring campaign, the remaining loyal Space Marine Legions are disbanded to for the far smaller 1,000 -man organisations known as Chapters. A portion of the Space Marines maintain their parent Legions' original names, badges and colours while the remaining Chapters take on new names and heraldry. The majority of these Second Founding Legions still serve the Imperium today. - [6]

Unspecified Date.M32 - Rise of the Adeptus Ministorum
 * The Emperor, always an object of veneration, only increases his following after being joined to the Golden Throne. Many Imperial cults arise over the following centuries, the majority of which are united into a larger body known as the Ecclesiarchy. This powerful body gains momentum until, in the thirty-second millennium, it is granted the status of official religion of the Imperium and the title of Adeptus Ministorum. It is only a few centuries later that Ecclesiarch Veneris II receives a seat amongst the High Lords of Terra, and after 300 years, the seat reserved for the Ecclesiarch is made permanent. - [6]

544.M32 - The Beast Arises
 * The Orks rampage across the Imperium on a massive scale. The number of attacks grow until it becomes the greatest greenskin invasion that the galaxy has ever known, eclipsing even the one defeated by Horus upon the world of Ullanor, which earned him the title of Warmaster. Nothing is safe from the Orks' primal desire to conquer the galaxy, and their widespread advances are only halted when the Imperium resorts to the most extreme of measures, at great cost to the Adeptus Astartes. - [6]

546.M32 - The Beheading
 * The internecine politics of the Imperium take a calamitous turn when the High Lords of Terra are slain to a man at the orders of Drakan Vangorich, the Grand Master of the Officio Assassinorum. This marks the beginning of a hundred year period of anarchy. At great loss, a Space Marine retribution force delivers the Emperor's justice to Vangorich. - [6]

646.M32 - Reunited
 * Agnathio, Chapter Master of the Ultramarines, unites over fifty leaders from other Chapters of Space Marines and arrives upon Terra. Such a show of power and faith puts an end t the squabbling for the contentious seats of the High Lords of Terra that has consumed the differing factions since the Beheading. In locked council with the mightiest of Mankind's warriors, such matters were quickly sorted. None know exactly what was done or said, but when the Space Marines departed back to their far-scattered missions, there once again sat twelve High Lords of Terra. If there was further dissension, none dared speak it aloud. - [6]

This pedates the Warp-drive's invention in the Age of Technology and suggests radical time stream disorders. Transmissions picked up suggest the Blade of Infinity is trying to communicate some type of warning, but before much can be deciphered, it once again disappears into the Warp. In its wake comes an invasion fleet of Chaos Space Marine Legions, fell does that wreak much havoc. The ship ''Blade of Infinity' re-emerges several more times in subsequent years, always as a harbinger of further Warp incursions. - [6]

Millions of ships are lost in the resulting upheaval and entire sub-sectors slide once more into barbarism without the dictates f the Adeptus Terra to keep them in line. It is a steep cost for victory. - [6]

Upon cardinal worlds, Arch-Deacons to lowly pilgrims claim to have seen statues of the divine Emperor shed tears.

822.M41 - Abaddon's Quest
 * Chaos Warmaster Abaddon raids the Maiden world of Ildanira, seeking a long-lost artefact. He is driven off by forces of the Alaitoc Craftworld. Such an action is minor compared to the many ongoing wars, but its portents loom large. - [6]

853.M41 - Roots of Corruption
 * The uprising on Krandor III, thought to have been suppressed over fifty years previously, has once more grown strong.

Three Space Marine Chapters, led by the Imperial Fists, secure resources, artefacts and a few Adeptus Administorum officials before Exterminatus is mercifully delivered.

The psychic backlash also banishes the Bloodtide and the Daemons it had drawn forth. - [6]

883.M41 - Armoured Assault
 * he Cadian 423rd spearhead, led by Knight Commander Pask, is the largest armoured assault since the Battle for Tallarn.

With much loss, Badab falls, but Lugft Huron and some 200 of the Astral Claws escape, taking refuge in the Maelstrom of Ultima Segmentum. There, they change their name to the Red Corsairs and become dreaded pirate raiders. Huron adopts the title of Blackheart and continues to recruit more renegades to join him. - [6]

907.M41 - Green Infestations

941.M41 - Second War for Armageddon
 * The largest and most powerful Ork in millennia, Warlord Ghazghkull Mag Uruk Thraka, leads a vast Waaagh! that, after much rampaging, meets its match upon Armageddon, a planet vitally important to the Imperium.
