HERIOT (AS. heregealu, militaiy apparel, from lien', Goth, harjis. OHG, heri, Ger. Heer, OC'hurch Slav. kara. OPruss. karjis. OPers. kara, army + grntu, equipment). In old English law, a customary tribute of goods and chattels, pay- able to the lord of the fee on the death of a freehold tenant. It may have had its origin in the practice of returning to the lord the martial equipment which he had furnished to his vassal. But in course of time it came to be regarded as a form of relief (q.v. ). payable by the heir on succeeding to the inheritance, as a sort of in- heritance tax or death diity. If a vassal fell in battle in the service of his lord, no heriot was demanded. As heriots were due only of tenants who held by knight's service, they disappeared with the abolition of military tenures. Nominal- ly, however, the right still exists in England in connection with copyhold estates, but it is in practice obsolete. See Tribute. HERIOT, her'i-ot, George (1.563-1624).
