The Jews in Castilian Medieval literature: people, genus or nation?

Castilian Jews came to see themselves as a separate community very early on, but did the Christians see them as part of the kingdom or rather as foreigners? This paper aims at understanding the semantic shift that took place in the kingdom of Castile between the 13th and the 15th century, and which led Christian theologians and jurists to exclude Jews and conversos from Castilian nation-building. The concept of "nation" appeared late in Castile and, to analyze the issue, it is advisable to define the meaning of the Latin and Castilian words Iudaei and judios, Hebreus, Iudeorum populus, populus Israelitici, genus or generatio Iudaeorum, gentes and pueblo, which were used in legal, historical and religious texts written in the kingdom of Castile during the Late Middle Ages.
