feudorum libri
Feudorum Libri (fyoo-dor-[schwa]m lI-brI). [Latin “the books of the feuds”] Hist. The Books of Feuds, a five-book compilation of Lombardic feudal law published in Milan around 1152, during the reign of Henry III. • This unofficial compilation was the main source of tenure law among the nations in Europe. It was widely used in medieval law schools and courts in Italy, France, and Germany. The Feudorum Libri were probably known in England but had little effect other than influencing English lawyers to study their own tenure system more critically. — Also termed Consuetudines Feudorum; Usus Feudorum.
