==== First Black Crusade ====

Despite there being eleven more events of the same name, the first Black Crusade was a watershed event in the history of the Imperium, if for nothing else than it established the relationship between Chaos and the Imperium for the next several millennia. After the events of the War of the Beast, Chaos regrouped and spent the next few centuries rebuilding and licking its wounds. Despite the events of the War of the Beast, Chaos had essentially made it to the Imperium’s door the first time around, several of the primarchs (e.g., Sanguinius, Angron, Horus) had died during or since, and Chaos could replace its losses (orks, daemons) much more easily and rapidly than the Imperium could replace theirs.

Chaos expected the Imperium to be permanently crippled, and the Imperium responded with a fist to their collective faces.

Making matters worse for the forces of Chaos was the unanticipated presence of the Eldar, who had started helping human forces in larger numbers in the years since the WotB. It took some time before the forces of Chaos realized they were sticking their hand into a cheese grater and pulled back to reformulate their strategy. This was far from the end of the first Black Crusade, and there were still significant losses for the Imperium (Dorn, Abbadon) but by the end of it the relationship between Chaos and the Imperium was clear. The Imperium was no flash in the pan that would crumple after one serious battle. If Chaos wanted to win, it would have to fight every inch of the way to get there. Later Black Crusades took this lesson in mind, and have become all the more dangerous for it.
