'''Tithe Grade''', also named the '''Great Harvesting''' or '''Terra's Due'''<sup>2</sup> refers to the amount of materials an Imperial world must supply to the #redirect [[Administratum]]. The size of the tithe depends on the type of world it is applied to. A tithe can be any form of material: food, weapons, minerals, people, etc.. It is the duty of [[Planetary Governor]]'s to ensure the tithe of their world is paid, and any world which fails to pay its tithe meets with vicious reprisal from the [[Adeptus Terra]]. However as long as the planetary ruler dutifully pays his worlds tithe, he may rule the planet in almost any way he sees fit.<sup>2</sup> [[Space Marine]] [[homeworld]]s do not normally have tithes, and are given the tithe grade [[Aptus Non]] while [[Agri world]] tithes generally refer to how much of the planet's food production must be supplied. ==Known Imperial Tithe Grades<sup>1</sup>==*[[Aptus Non]] (also Adeptus Non)*Solutio Tertius*Solutio Prima*Solutio Extremis*Decuma Particular*Exactis Tertius*Exactis Prima*Exactis Particular*Exactis Extremis ==Sources==*<sup>1</sup>[[Warhammer 40,000 3rd Edition Rulebook]], pp. 114–115*<sup>2</sup>:[[Warhammer 40,000 6th Edition Rulebook]] pg.148 [[Category:Imperium]][[de:Tributrate]][[fr:Grade de la Dîme]]
