With so many options to choose from, it can be overwhelming to pick the perfect army for your style of play.

We’ll start by exploring Warhammer 40k’s three super-factions: the Imperium of Man, the Chaos, and the Xenos Races.
Warhammer 40k Factions: The Imperium of Man
The Imperium of Man stands as a colossus amidst the grim darkness and races of the far future in the Warhammer 40k universe. It is an empire of staggering proportions, spanning countless worlds across the galaxy, held together by faith, militarism, and the iron will of its rulers. Founded in the aftermath of the Horus Heresy, a catastrophic civil war that nearly tore humanity apart, the Imperium is ruled by the God-Emperor, a near-dead deity entombed within the Golden Throne on Terra.
Life within the Imperium is harsh and unforgiving. Every citizen is a cog in the vast machinery of war and survival. The society is defined by rigid hierarchy, dogma, and intolerance. Dissent is swiftly crushed, and heresy is met with brutal retribution.
The Imperium’s military, the Astra Militarum, is the largest fighting force in the galaxy, supplemented by the genetically-enhanced super soldiers known as Space Marines, the cybernetic warriors of the Adeptus Mechanicus, and countless other forces. Their primary mission is to defend humanity against the myriad threats that seek its extinction, from daemonic incursions to Xenos invasions.
Despite its vast power, the Imperium teeters on the brink of collapse, beset by enemies both within and without. Yet, amidst the darkness, there are those who cling to hope, believing that through faith, sacrifice, and unyielding determination, mankind will endure, and the Imperium will stand eternal.
Warhammer 40k Factions: Chaos
Chaos factions in Warhammer 40k are the antithesis of order and the sworn enemies of the Imperium of Man. While the Chaos Gods have always existed, they truly came into focus for 40k when the once-loyal Space Marines turned during the Horus Heresy. Since then, they have become twisted parodies of their former selves, dedicated to serving the malevolent Chaos Gods.
Khorne, the Blood God, revels in the slaughter and carnage of battle, his followers driven by an insatiable thirst for bloodshed. Nurgle, the Plague Lord, spreads disease and decay, and his followers transform into grotesque abominations. Tzeentch, the Changer of Ways, weaves schemes and manipulates events from the shadows, his followers wielding sorcery and deceit. Slaanesh, the Prince of Pleasure, indulges in excess and hedonism, his followers seeking ever greater sensations and sensations.
United in their desire to see the Imperium and Xenos destroyed and reality itself torn asunder, the Chaos factions wage an unending war across the galaxy. They corrupt and subvert, turning loyal citizens and even entire planets to their cause. Yet, amidst the chaos, there are those who resist, standing as bulwarks against the tide of darkness.
Warhammer 40k Races & Factions: Xenos
The Xenos factions and races in Warhammer 40k are formidable adversaries to humanity and Chaos alike. These extraterrestrial Warhammer 40k races possess diverse cultures, technologies, and motivations, each with unique strengths and weaknesses.
The Tyranids, a ravenous swarm of bio-engineered horrors, seek only to consume and assimilate all life in their path, driven by the insatiable hunger of the Hive Mind. Their relentless advance threatens to engulf entire star systems in an unending tide of chitin and claws.
The Aeldari, ancient and enigmatic, once ruled a vast empire that spanned the galaxy. Now dwindling in numbers, they seek to protect their remaining strongholds and manipulate the fates of lesser races to ensure their survival. Masters of psychic power and advanced technology, they are a force to be reckoned with. They also have multiple offshoots, including the Drukhari (a much more evil faction focused on themselves and themselves only), the Harlequins (they record the history of the Eldar through dances and plays), and the Ynnari.
The Orks, brutal and warlike, thrive on conflict and revel in the joy of battle. Their society is built around constant warfare, with warbands led by the biggest and strongest among them. Despite their crude technology, their sheer numbers and ferocity make them a formidable foe.
The Necrons, ancient machines entombed in living metal, awaken from eons-long slumber to reclaim their dominion over the galaxy. With technology beyond human comprehension and an unyielding determination to eradicate all organic life, they are a relentless and unstoppable force.
The Tau Empire has emerged over the past few years as a rising power. United under the banner of the Greater Good, they espouse ideals of unity, progress, and technological advancement. The Tau’s society is built upon a caste system, each contributing to the collective whole. Their military, spearheaded by battlesuits and advanced weaponry, emphasizes precision and firepower over brute force. While their expansionist ambitions often bring them into conflict with other factions, the Tau seek to spread their vision of harmony and enlightenment, believing that cooperation and diplomacy can forge a better future amidst the grim darkness of the far future.
The Leagues of Votann are the latest main faction of Xenos. Hailing from the world of Votann, they are a confederation of technologically advanced societies united by a common purpose. Their mastery of science and engineering rivals even that of the Adeptus Mechanicus. The Leagues possess formidable war machines and formidable warriors, often deploying advanced weaponry in battle. While they may not hold the same prominence as the Imperium or the Chaos factions, their presence in the galaxy is felt.
These Xenos factions and races in Warhammer 40k stand as a constant reminder of humanity’s vulnerability, each seeking to carve out its own place in the galaxy at the expense of all others.

These fallen heroes were once part of the mighty Space Marine Legions during the Horus Heresy, a cataclysmic civil war that shattered the Imperium. Led by their traitorous Primarchs, they rebelled against the Emperor, seeking to plunge the galaxy into darkness.

The Aeldari were once a highly advanced and psychic race, possessing unparalleled artistry, technological prowess, and a profound connection to the warp. However, their decadence and pursuit of excess led to the Fall, an event that birthed Slaanesh and devastated their empire.
Now divided into factions, the Aeldari are led by their Craftworlds, enigmatic starships that carry their surviving people across the galaxy.

The Space Wolves trace their origins back to the distant days of the Horus Heresy, a time of betrayal and turmoil that nearly tore the Imperium apart. Originally known as the VI Legion, the Emperor himself chose them to be his executioners, his Wolves, in the face of insurrection.
The Space Wolves hail from the icy death world of Fenris, a harsh and unforgiving planet that has shaped their culture and identity. They are savage warriors who emphasize individual prowess, close combat expertise, and primal instincts.
The Space Wolves’ gene-seed has been modified with the genetic traits of the ancient and mysterious Canis Helix, granting them heightened senses, enhanced strength, and the ability to transform into terrifying wolf-like forms known as “the Curse of the Wulfen.” Explore the lore, how to play, index rules, and more in our Warhammer 40k Space Wolves army guide, and bring the glory to Russ!
World Eaters
The World Eaters are a fearsome and savage Chaos Space Marine Legion known for their relentless bloodlust and insatiable thirst for combat. Once a proud and loyal Legion of the Emperor’s Space Marines, they fell to the corruption of Chaos and transformed into a brutal and chaotic force.
The World Eaters, originally known as the XII Legion, were led by their Primarch, Angron. Angron was a fierce and powerful warrior whose rage and thirst for battle were unparalleled. The World Eaters were known for their brutal close combat tactics and unwavering devotion to martial prowess.
However, during the Horus Heresy, a galaxy-spanning civil war, the World Eaters succumbed to the temptations of Chaos, particularly the Blood God Khorne. They abandoned their former loyalties and embraced the path of slaughter and carnage, becoming the embodiment of Khorne’s bloodlust.
The World Eaters cast aside their former name and adopted the title of “Khornate Berserkers” as they sought to shed the blood of their enemies in the name of Khorne. To enhance their combat prowess, they underwent bloody rituals and surgeries, replacing their limbs with brutal cybernetics and implanting Butcher’s Nails within their skulls to heighten their aggression and pain tolerance. Take all the skulls for Khorne with our Warhammer 40k World Eaters army guide, packed with all the index rules, how-to-play, lore, and more!
