A '''Tithe Grade''' is a name given to a planet denoting the amount and type of materials a planet must supply to the [[Administratum]]. The size of the tithe depends on the type of world it is applied to. A tithe can be food, minerals or people. [#redirect [Space Marine]] [[homeworld]]s do not normally have Imperial Tithe's, and as such are given the title [[Adeptus Non]]. [[Agri World]] tithes generally state how much of the planetary production must be supplied. [[Category:The Galaxy]]
