ASSISES OF JERUSALEM. The name of a code of feudal law, made at a general
assembly of lords, after the conquest of Jerusalem. It was compiled
principally from the laws and customs of France. They were reduced to form
about the year 1290, by Jean d'Iblin, comte de Japhe et d'Ascalon. Fournel
(Hist. des Avocats, vol. i. p. 49,) calls them the most precious monument
of our (French) ancient law. He defines the word assises to signify the
assemblies of the great, men of the realm. See also, 2 Profession d'Avocat,
