The Libri Feudorum (the "Books of Fiefs") - Book by -

The Libri Feudorum (the "books of fiefs") are the earliest written body of feudal customs in Europe, codified in northern Italy c.1100-1250, which gave rise to feudal law as a branch of civil law. Their role in shaping modern ideas of feudalism has aroused an intense debate among medievalists, leading to deep rethinking of the "feudal" vocabulary and categories.
