This book presents an edition of two treatises that examine the legal issues that arose during the Hundred Years War, namely the laws governing the succession to the French crown, English claims to territories within France, and the responsibility for the breeches of various treaties and truces. The first treatise, Pour ce que plusieurs, was written in 1464 by a French diplomat and administrator, Guillaume Cousinot, and is most famous for its part in establishing the myth that the royal succession in France was determined by a otiose law code of the Franks, the Salic Law. The second is an English response to these arguments, A declaracion of the trew and dewe title of Henrie VIII, written during the reign of Henry VIII (1509-1547). The declaracion provides valuable evidence of English reactions to the rhetoric and propaganda generated by the French crown at the end of the middle ages.
