History
The Imperium is established on Terra (Earth) in the 30th millennium AD as the planet's sole authority; several centuries later, it embarks on a Great Crusade, an interstellar crusade intended to bring all human-settled worlds in the Milky Way galaxy under its banner. Over the course of two Terran centuries, the Crusade reaches star systems more than 50,000 light years away from its original staging point in the Sol (Solar) System, assimilates millions of worlds into the Imperium, and gives Humankind a dominant position among the galaxy's species; according to Imperial propaganda, it is humanity's "Manifest Destiny" to rule the galaxy.
Early in the 31st millennium, the Crusade comes to a sudden stop as the Imperium is nearly torn asunder in a galaxy-wide civil war known as the Horus Heresy; the war decimates and eventually redefines the Imperium. Following the Horus Heresy, the crippled institution undergoes a centuries-long, often violent rebuilding.

Famous quotes containing the word history:
“One classic American landscape haunts all of American literature. It is a picture of Eden, perceived at the instant of history when corruption has just begun to set in. The serpent has shown his scaly head in the undergrowth. The apple gleams on the tree. The old drama of the Fall is ready to start all over again.”
—Jonathan Raban (b. 1942)
“Anything in history or nature that can be described as changing steadily can be seen as heading toward catastrophe.”
—Susan Sontag (b. 1933)
“The history of every country begins in the heart of a man or a woman.”
—Willa Cather (1876–1947)
