{{ImperiumPortal}}{{otheruses|USE=Imperial term|OTHERUSE=Short Story by Ben Counter|OTHERPAGE=The Tithe (Short Story)}}'''Tithe Grade''', also named the '''Grand Harvesting''' or '''Terra's Due'''{{Fn|2}} refers to the amount of materials an Imperial world must supply to the [[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, et cetera. Despite the number of agencies tracking tithes, due to the sheer size of the Imperium and the difficulty of [[Warp]] travel makes time consuming process of tithe collection riddled with confusion and inefficiency.{{Fn|2}} One of the most common forms of tithe is by providing one tenth of their [[PDF]] troops to serve in the [[Imperial Guard]].{{Fn|4}}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 #redirect [[Adeptus Terra]]. At the slightest breach of protocol, Imperial officials will often immediately execute the Governor. However as long as the planetary ruler dutifully pays his worlds tithe, he may rule the planet in almost any way he sees fit.{{Fn|2}}[[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 Tithe Grades{{Fn|1}}==*[[Aptus Non]] (also Adeptus Non)*Solutio Tertius*Solutio Prima*Solutio Extremis*Decuma Particular*Exactis Tertius*Exactis Prima*Exactis Particular*Exactis Extremis*Experima{{Fn|3}}==Sources==*{{Endn|1}}: [[Warhammer 40,000 3rd Edition Rulebook]], pp. 114–115*{{Endn|2}}: [[Warhammer 40,000 6th Edition Rulebook]] pg.148*{{Endn|3}}: [[Inquisitor Conspiracies 3 - Heavenfall]], pg. 33*{{Endn|4}}: [[Codex: Astra Militarum (6th Edition)]] - ''Raising the Tithe''[[Category:Imperium]][[de:Tributrate]][[fr:Grade de la Dîme]]
