Probably the most famous of all the debates and attacks on Judaism was instigated by Raymond of Penaforte. Christiani, a converted Jew, compelled King James of Aragon to force a debate between him and Moses ben Nachman (Nachmanides). The Jews, afraid that no matter the outcome they would lose, pleaded with Nachmanides to withdraw, but the King ordered him to continue. Although Pope Clement IV insisted on the outcome, the King was so impressed that he rewarded Nachmanides with a present of 300 maravedis. Pablo was given permission to continue these debates throughout Aragon, with the Jews having to pay his expenses.
