9,000 BC:

Death of first Terran civilization, building of the Sphinx, birth of the Emperor.


8,000-2,000 BC:

Birth of Khorne, Tzeench & Nurgle (gods of chaos).


750 BC -476 AD:

Roman Empire.



Eldar learn secrets of warp technology from the Slann.



Old Slann culture dies out and/or leaves. Slann warn Eldar of the fall.


2,043 (043.M03):

Beginning of Second Epoch, major cultural, natural and technological changes and disasters nearly destroy Mankind but Man prevails and prospers once again.



Mars Settled.



Mars Terraformed.



Warp Discovered.







Humanity begins to colonise nearby solar systems using primitive sub-light spacecraft. At first progress is slow and the new colonies must survive as independent units isolated from Earth by up to ten generations of travel. The period of the next ten thousand years will later be known subsequently as the Golden- and Dark Age of Technology.



Keeper Cripias records this as the end of the Golden Age. The Golden Race of Men (Terrans) becomes depended on the Stone Race of Men (Martians) and their artifices and as such the Stone Men prevail.  Sometime within the next 5,000 years the Men of Stone create the Iron Men (Robots and Titans) to help in the building of their Empire.



Humanity explores and settles the galaxy following the discovery of Warp drives allowing more rapid dispersion, first alien races encountered. All done in less than 1000 years.



Navigator gene isolated, Navigators are powerful psykers able to pilot ships through the warp, and so warp travel becomes even faster. Navigator families and cartels become powerful political entities.  The Expansion of Humanity covers most of the galaxy, Standard Template Construct (STC) system is perfected to aid new colonies. Titans are developed for rapid land movement.



Squat history begins with the Age of Founding.  The mining colonies of the Home Worlds are in constant contact with Terra and the Squats show no distinction from normal Humans.



Alien wars. Mankind encounters and fights with Orks and Eldar.



S.T.C lost. Appearance of psychic powers in humans, and warp entities (daemons)



Appearance of abhumans: Homo Sapiens Giganticus, Rotundus and Minimus. Major civil wars. Civilisation begins to crumble as widespread insanity and insurrection tear many colonies apart. Many worlds fall to daemons who possess unprotected psykers and subjugate worlds.



Horiax Treatise mentions genetic alteration techniques.



The Eldar Maiden Worlds are seeded.












Keeper Cripias' history states that at this time, the Stone Men and Iron Men (now grown from servants to equals) fall into warring with each other.  The Iron Men have no soul and the Stone Men in the final acts of self-preservation, annihilate the Iron Men, including those who remain loyal, in battle.  Thus the Age of strife begins.



Warp Storms isolate many parts of the galaxy including Earth and the Squat Home Worlds. This marks the beginning of the Squat Age of Isolation. The Home World mining colonies become self-sufficient, independent strongholds. During this period the Engineers Guild develops into a sociopolitical power and strongholds form complex political and trading agreements that become Leagues.



The Cult Mechanicus is founded on Mars as a survival mechanism to maintain the technology necessary for life on the planet.  The Cult constructs their High Altar and builds their vast fighting machines based on Titan technology.  The Mechanicus spacecraft are unable to leave the Sol system.



A slight abating in warp storms leads to encounters between the Squat Home Worlds and alien races known as the Age of Trade.  Squats use their tremendous mineral wealth to trade for weapons, foodstuffs, and high-tech systems with the Eldar and Orks.  During conflicts between the Orks and Eldar, the Squats remain neutral and maintain trade with both sides.



Studying the pattern of warp storms, Mars prepares massive expeditions consisting of entire Titan Legions and thousands of servitors to explore the galaxy.  The successful colonies become the Forge Worlds and Knight Worlds of the Adeptus Mechanicus.  This process continues throughout the Age of Strife.



A probe is dispatched from Terra, its mission to reach the utmost limit of the universe (14,000 years later it has yet to begin its return trip and many of the signals identified sent by the probe have been Orkish in nature).



Civil war on Earth - No longer able to acquire sufficient food or resources and without access to the wider galaxy, Earth devolves into petty fiefdoms ruled by warlords. Billions die as a result of war and starvation. 



Grunhag the Flayer, Ork Warlord attacks the Squat Homeworlds with a huge fleet.Many strongholds are wiped out by the Orks, the epic ballad "The Fall of Imbach" commemorates one such destruction. This marks the beginning of Squat hostility towards Orks and distrust towards Eldar who stayed neutral in the conflict. This marks the end of the Age of Trade and the beginning of the Age of Wars between Squats, Eldar and Orks.



Earliest modified warriors aid the Emperor in conquest of Terra.



Earth is reunited under a new leader (the Emperor), this warlord begins a slow push to the stars.  Upon his arrival on Mars, the Emperor is recognized as the Cult Mechanicus' Omnissiah of legend.



20 Primarchs are genetically created as a new super human race by the Emperor: Lion El'Johnson, Fulgrim, Perturabo, Jaghatai Khan, Leman Russ, Rogal Dorn, Night Haunter, Sanguinius, Ferrus Manus, Angron, Robert Guilliman, Mortarion, Magnus the Red, Horus, Lorgar, Vulkan, Corax and Alpharius. The Chaos powers  recognise their potential and scatter them across the galaxy.



Grayba's Theorem demonstrates how Primarch genetic data can be used to stabilize genetic development of new Space Marines. 20 First Founding Space Marine Legions are created, each based on the genetic template of their Primarch. [Click here to find out more about the First Founding.]



Eldar build Craftworlds heeding the warnings given to them by the Slann.



Fall of the Eldar: Eldar society teeters on the brink of Chaos and finally collapses, thus creating the Chaos god Slaanesh. Slaanesh's pyschic scream tears at the universe and all Eldar within thousands of light years are destroyed in an instant. A vast black hole opens and the Eldar worlds are consumed within it. Only a few of the fleeing Craftworlds furthest away from the epicentre survive. Today this black hole is known as the Eye of Terror. This rift caused warp storms to become passive and human worlds throughout the galaxy were brought into contact once more. The Age of Strife ended and mankind replaced the Eldar as the galaxy's most vital race.



Founding of the Astronomican, a psychic navigation beam directed by the Emperor himself. Interstellar travel becomes easier and quicker.




Age of the Imperium begins with the Great Crusade, for the next two hundred years, the Emperor and the Space Marine Legions gradually carve out the scattered Imperium of Man. During this time the Emperor is reunited with the Primarchs who are united with their Marine chapters. The greatest of the Primarchs is Horus. Human galaxy reclaimed under Pax Imperialis.



Accelerated gene-culturing techniques are implemented, reducing processing time to create a Space Marine to a single year. There are unseen fundamental flaws.



Eldar Shrine of Asur founded.



The Lunar Wolves are renamed Sons of Horus in honor of their Primarch following the Warmaster's Ullanor Campaign.

Iron Warriors Traitor Legion virus bomb Tallarn and lay siege to the planet.  Reinforcements pour in from both sides of the conflict.  Although the Imperium is eventually victorious casualties are severe, such as the Ultramarines with only 1 in 10 surviving.



Battle of Molech - Three Titan Legions and over a hundred IG regiments and Knight households defend Molech against the Warmaster Horus and his armies.  Knights of the Ruling Household (Devine) are seduced by Slaanesh during the initial stages, and betray Imperial forces during the main Chaos assault. Only 1 in 100 Imperial soldiers survive the battle, the future Daemon Knights of Slaanesh daemonic war machines are from House Devine.



Siege of Terra - Horus lays siege to the Imperial palace.Imperial defenders fall back to the Inner Palace and the Blood Angels hold at the Ultimate Gate. [Read about seige of Earth here]



The Emperor's Children fall upon the civilian population turning more than a million prisoners into an array of drugs for their pleasure.



The Emperor, Rogal Dorn and Sanguinius teleport onto Horus's battle barge, Sanguinius is separated from the Emperor and chances upon Horus. Horus offers him a place by his side and pick of human worlds, but Sanguinius refuses and is slain by the Warmaster in single combat. The Emperor then kills Horus and is so badly wounded that he is incarcerated within the Golden Throne to preserve his life energy.



Great scouring. Rebel forces throughout the galaxy are exterminated (Chaos forces known as Traitor Legions retreat to the eye of terror.). This marks the end of the Horus Heresy.



High Lords of Terra convene to provide guidance in the absence of the Emperor.



Roboute Guilliman, Primarch of the Ultramarines Legion, compiles the first Codex Astartes. This volume lays down new organisational doctrine. This results in the Second Founding of Space Marines. Loyal Space Marine Legions are broken down into smaller Chapters, each numbering roughly 1,000 fighting troops, so that no one master can wield as much power as Horus did. 23 new chapters are created. One Chapter retains name and heraldry of Legion, other Chapters re-named and given icons and uniforms as detailed in Codex Astartes. The Grey Knights are founded in secrecy at this time as a Chapter specifically tailored to destroy daemons, it is not known from what geneseed they were created although rumours speak of the Emperorís own geneseed. 



Chaos forces retreat into the Eye of Terror.  Worldeaters fight Emperor's Children on the daemon world of Skalathrax.  Kharn's betrayal shatters the once united Worldeater Legion into separate, roving warbands.



Primarch Leman Russ of the Space Wolves takes his most favored retainers and departs from the Feast of the Emperor's Ascension, never to be seen or heard from again except in visions.  His armor is discovered during the second Great Hunt at the Temple of Horus on Rudra, a world on the edge of the Eye of Terror.



The surviving Wolf Lords of the Space Wolves gather together and elect Bjorn their leader, awarding him the title Great Wolf.  Bjorn gathers together the Chapter and announces the Great Hunt in an attempt to find Leman Russ.  The Great Hunt ends in failure and sadness.



The first prototypes of the Vindicator Close Support Armored Vehicle are created during the third Rothern I pacification by Techmarines of the Ultramarines.



7th Founding, Fiery Lions chapter created out of Ultramarines geneseed.



Fiery Lions chapter is issued the infamous Charter of Parmenio.



Magnus the Red, Primarch of the Thousand Sons launches a series of devastating raids on the worlds near Fenris in revenge for Prospero.  As well, Magnus taunts the Great Wolf Harek Ironhelm in visions.  An obsessed Ironhelm assaults what he believes to be the Thousand Sons' secret base on Gangava.  In reality, the Thousand Sons' Fleet besieges Fenris.  For forty days and forty nights, the defenders under the leadership of the Dreadnought Bjorn the Fell-Handed hold them off as a force of scouts under Haakon Blackwing are dispatched to Gangava and Harek.
Shamed and furious, Harek Ironhelm meets Magnus in battle on the slopes of the Fang itself.  Although he inflicts a terrible wound on Magnus, Harek is overcome and his crypt later becomes a shrine to the Space Wolf Rune Priests.



Temple of the Saviour Emperor recognised as the official religion of the Imperium.

Early M36

Incidence of warp storms increases. Imperium reels as Orks and other races rampage throughout a divided galaxy. Period known as the Age of Apostasy begins during which time the Administratum and the religious order of the Ecclesiarchy tore the Imperium apart from within. Sometime during this period the last of the Squat strongholds seceded from the Imperium.



"Mythos Angelica Mortis" detailing history/myths of Adeptus Astartes transcribed.



The Master of the Adeptus Astra Telepathica, Lord Phaedrus, is assassinated by Lord Vandire, the Master of the Administratum and Ecclesiarch and man behind the current corruption in the Imperium. Phaedrus could see through Vandires plots and deceits revealing his intentions.



In the anarchic Wars of Vindication the Grand Master of Assassins himself fell to the Assassin's knife. Or so it appears, suspecting such a plot the true Grand Master had replaced himself with a loyal Callidus assassin. After defeating Vandire's assassins in the conflict that involved nerve gases, neutronic warheads, and other banned weaponry the Grand Master departs into a self-imposed exile. Thereafter, the High Lords took special care to control the Officio Assassinorum so that, in theory, only traitors and heretics need fear it today.



Upon the death of High Lord Vandire, Sebastian Thor becomes 292nd Ecclesiarch following a two-month trial at the hands of the High Lords of Terra.  Thor begins to reform the Adeptus Ministorum, including such items as the Decree Passive issued by High Lords of Terra forbidding the Ecclesiarchy from maintaining an "armed force of men."  The Frateris Templar are duly disbanded but the Daughters of the Emperor (Adepta Sororitas) remain. The Fiery Lions Chapter of Spacemarines is awarded with the Retribution Class Battleship  Unguis Leoninus for acts of supreme bravery during the conflict.



Sebastian Thor, 292nd Ecclesiarch of the Adeptus Ministorum dies on Terra at the age of 112.  Over seventy million pilgrims file past the three-mile long passageway leading to his tomb in the first year alone. Ecclesiarch Alexis XXII succeeds him.

Zaraphiston's visions show Abaddon the Arx Gap, a stable route out of the Eye of Terror that bypasses the heavily defended Cadian Gate.  Abaddon begins his Ninth Black Crusade by dispatching a vanguard fleet to destroy the Imperial monitoring station on Arx.  The assault on Arx wipes out the defending Imperial Guard and station crew. The scout frigate Ascendance receives a plea for help.  Reinforcements four months later find no survivors or sign of those responsible.  Inquisitor Horst investigates.


The Planet Killer is completed and a massive effort begins to find enough crew to man it.  Zaraphiston binds several daemons to the huge vessel, greatly reducing the manpower needed to run it. As warp storms begin to engulf the Gothic Sector, Abaddon commands his subservient Warmasters to attack.



Abaddon leaves the Eye of Terror through the now clear Arx Gap, ordering his tech-priests to follow once the Planet Killer is operational.


Several patrol vessels in the Athena Sector find a number of Imperial vessel drifting uncontrolled.  The crews are all dead, disease fostering corpses.  Xebal Astolax, Magos Biologis registers evidence of blisters, sores and fungal growth as cause of death. Rumors begin of the reappearance of the Plagueclaw.  Watchposts around the Cadian Gate are put on close alert and Naval patrols are increased around Cadia.


Chaos cult activity increases in the Segmentum Obscurus.  Attacks are made on the hive world of Morganghast.  A Chaos attack on the Imperial world of Purgatory results in the disappearance of the artifact known as the "Hand of Darkness".  Another Chaos assault on the Ratling world of Ornsworld results in the theft of the Eye of Night, an artifact with mythical connections to the Hand of Darkness, and the death of millions of Ratlings.



A frigate-sized craft is detected in orbit of Hobart's planet.  Seventeen minutes after first contact, a massive energy pulse is detected and the craft's energy signal disappears.  An investigative team is dispatched to the wreckage to establish the source and nature of the unidentified craft.



A cataclysmic shockwave passes through the Warp engulfing the Gothic Sector and cutting it off from the rest of the Imperium.



Abaddon enters the Gothic Sector, using the Hand of Darkness to capture the  Blackstone Fortress at Rebo V. He then makes a rendezvous with the Planet Killer and takes it as his flagship. His first target is the Ecclesiarchy Cardinal world of Savaven, population 14 billion. Cardinal Klien orders the Imperial Commander to refuse Abaddon's demand for unconditional surrender. Abaddon uses Savaven as a trial for the Planet Killer, destroying the planet along with its population in less than an hour.



The Planet Killer arrives at Saviour, a highly populated system in Lysades sub-sector. After revealing the Planet Killer, Abaddon demands that Saviour's orbital docks begin producing ships for the Chaos fleet. The commander of Saviour has little choice but to agree, the lives of eleven billion people are at stake. With the threat of the Abaddon's Planet Killer, more and more worlds of the Gothic Sector surrender.


The Commander of Brinaga (in the Brigia system) receives warning that Abaddon may attack soon, in an attempt to capture Blackstone VI. All communications are lost with Brinaga shortly afterwards. A patrol vessel reports that the existence of Brinaga can no longer be confirmed.


Abaddon takes the Planet Killer to Fularis, where Blackstone I orbits Fularis II. While the captured Blackstone Fortresses destroy Fularis II. Abaddon uses the Planet Killer and its attendent fleet to shatter battlegroup Merlin that protects the system. Unopposed, the Planet Killer destroys the second moon of Fularis III, long suspected of being the lair of an Eldar pirate band.



The Planet Killer is spotted moving towards Stranivar in Bhein Morr. Stranivar has been blocked for two years, but still refuses to surrender. Communications are lost with Stranivar, an investigating fleet discovers much of the hive world devastated by meteors created by the destruction of all three of its moons.



The Lysades sub-sector of the Gothic Sector is almost entirely overrun by Chaos.


An Imperial patrol flotilla encounters the Planet Killer as it leaves warpspace, entering the Corain system. They attack immediately before the rest of Abaddon's fleet can arrive. After causing considerable damage, the Imperial fleet is finally driven off by the Planet Killer's immense arsenal. Abaddon's forces invade Corain VI and take over its mines. Loyalist guerrilla fighters report that considerable amounts of trikali crystal are shipped into orbit, where the Planet Killer is stationed. Trikali crystal is mainly used in the anti-magnetic containment fields of warp generators and plasma reactors.



Abaddon invades Drakulu system and enslaves the two million inhabitants of the system's main planet, an agri-world. It is widely believed that many of these end up as sacrifices for Zaraphiston's magics, the remainder forced into service as crews on the Planet Killer and other vessels.



Abaddon sends his battlefleet accompanied by the three Blackstone Fortresses to try and stem the Imperial reinforcements by attacking the Tarantis system.  The combined might of the Blackstone Fortresses results in the system's sun going supernova, in hopes to prevent the Imperium from using the jump point.


Abaddon takes the Planet Killer to neighboring Boeti. Utilizing its power, he eradicates the Adeptus Astra Telepathica facility in Boetia's asteroid belt, cutting off the navigational beacon that would have helped any Imperial ships daring to jump through the warp storms.



As Zaraphiston predicted, Warp storms in the Gothic Sector start to abate and Imperial reinforcements from the Tamahl Sector arrive along with several Space Marine Chapters leading to a new Imperial offensive.


Cooperating with the Eldar, Lord Ravensburg outmaneuvers Abaddon's fleet arriving at Schindlegeist five days before Abaddon.  As the Blackstone Fortresses move towards Schindlegeist's star, the battlecruiser Flame of Purity dives into the middle of the converging energy waves expending the Fortresses' power.  Abaddon flees with two Fortresses leaving the third behind.  The Angels of Redemption along with Imperial Naval personnel board the Blackstone Fortress resulting in its destruction.  The other Blackstone Fortresses in Imperial possession also self-destruct at the same time.  The status of the Fortresses in Abaddon's possess is unknown.


The Planet Killer under the command of Warmaster Malefica Arkham is dispatched to attack Arimaspia as a diversion.  Although Abaddon is defeated at Schindlegeist, the Planet Killer succeeds in destroying two of the five planets that make up the Arimaspia system.


Abandoned by Abaddon, Malefica Arkham tries to use the Planet Killer to carve out an empire of his own. The world of Gonnacrash in the Quinrox Sound swears sovereignty to his rule, but, as he moves the Planet Killer to Kharlos II, Arkham is discovered by Omega squadron, freshly arrived from outside the Gothic Sector. With no support vessels, Arkham decides to attack, but the Planet Killer is eventually destroyed by the continuous torpedo fusillade of the four Lunar class cruisers.



The retaking of the Gothic Sector takes eight years.  The High Lords of Terra reward the members of Battlefleet Gothic with a specially constructed monolith bearing their names in the Chamber of Heroes in the Imperial Palace.



An expedition is launched by Inquisitor Horst to recover the hulk of the Planet Killer for study by the Adeptus Mechanicus. No trace of it can be found, and there are rumors of a Black Legion vessel being sighted in the vicinity.  Although its destruction cannot be confirmed, there have been no confirmed sightings of the Planet Killer either.



Inquisitor Horst departs to discover the fate of the Blackstone Fortresses in Abaddon's possess.  He is never heard from again.

First Battle for Armageddon.  Armed rebellion breaks out in six hives. The revolts are put down on the second continent, but continue in the widely scattered hives of Armageddon Prime.


A vast space hulk arrives carrying a massive daemon world army led by the Daemon Primarch Angron of the Worldeaters Legion.  After taking Armageddon Prime, Angron stops to draw more chaotic energy to the planet.


Reinforcements arrive from the Space Wolves Chapter.  As Angron leads his forces against Infernus and Helsreach hives, Logan Grimnar releases his reserve of a full company of Grey Knights.  Teleporting into the center of Angron's forces, the Grey Knights do battle with the Daemon Primarch and his Greater Daemon bodyguard.  In the end, Angron is cast back into the warp by remaining Grey Knights which number less than a dozen.  The Space Wolves launch a counter-attack routing and destroying the Chaos horde.


The population of Armageddon is sterilized and marched to huge forced labor camps isolated from the hives, where they spend the remainder of their days.  Billions of new workers are brought in to repopulate the planet.  Logan Grimnar refuses to forgive the Adeptus Administratum for what he sees as a great betrayal of the innocents.
