See Warhammer 40,000 for detailed information. This page lists events in the timeline according to the game's manual, and while some are still considered canon, many more are not.



From manual

The galaxy contains some four hundred thousand million stars. Only a fraction are presumed to have habitable planetary systems, and only a fraction of these have been investigated. Most are situated within the spiral arms between ten and forty thousand light years from the galactic centre. Even the human controlled Imperium, by far the largest and most widely distributed of all stellar empires, contains only a tiny fraction of the galaxy's stars. 

Humanity is one of many races in the galaxy, but none are so widely distributed or so numerous as humans. Most occupy only a single world or a small group of worlds. Only a few alien races posses technology which rivals that of the Imperium - Orks, Eldar and Tyranids.

This is a time of superstition, in which unfathomable technology has been enslaved to the forces of mysticism and madness. To ordinary humans, scientific thought represents an abhorrent perversity, a corruption of honour and religious virtue. Even to those who deal with technology, science and magic have become inseparable. Warp engines must have runes engraved upon their sides, and lasers requires the blessing of the Gods of Battle. 

This is a universe in which the gods, mysticism and magic are real.
