How did Nahmanides Describe Christendom?: Origin, People, History

I will make a lecture on Nahmanides`s description of Christendom. Nahmanides (1194-1270) was an influential Jewish leader of the Aragonese Kingdom. He attended a public disputation with a Dominican friar, Paulus Christiani. According to his report, Nahmanides made some aggressive comments on messiahship of Jesus and the doctine of trinity. Moreover Nahmanides tried to describe Christendom, especially origin of Christian people (not Christianity as religion), relationship between Jewish and Christian people, and a history of Christian world.

My focus will be on a series of questions on the case of Nahmanides in the discourse of the medieval Jewish polemical literature. What kind of sources, Jewish and non-Jewish, did he read? How did he interpret biblical verses of the story of Jacob and Esau, some commandments, and messianic prophecies? What did he think on the conversion of religions, from Judaism to Christianity?

In my lecture I will cite some passages from the works of Nahmanides, such as Viku`ah ha-Ramban, Sefer ha-Geulah, and Torah Commentary in order to explain his description of Christendom according to my arragement of topics. In addition to this, I will consider his concept of "Christianity" or "religion" from his usage of terms.
