The Imperium is primarily an interstellar tribute empire, allowing its member worlds to largely govern themselves as long as they recognise the authority of the Emperor and His servants and support the state religion, the
Imperial Cult, which holds the Emperor to be the one, true God of Mankind. Every world of the Imperium must also pay the Imperial taxes levied on them in the form of men and materiel that is known as the
Imperial Tithe. These resources go to the service of the
Astra Militarum and the
Imperial Navy, the armed forces which keep the Imperium united and safe. The Imperial Tithe supports the overall economy of the Imperium by redistributing resources where needed, usually to shore up one region of the Imperium where conflict is raging by drawing resources from more peaceful
sectors.
