Rabbi Moshe Ben Nachmon (Nachmanides, 1194-1270) wrote a commentary on Torah and Jewish law and more than 50 other lucid and logical works. He participated in a disputation (theological argument with the Catholic Church) in Barcelona in 1263; although he won, he was forced to flee Spain, and as a result all future disputations forbade the Jewish participants to answer frankly. At age 72 he settled in Jerusalem, reorganized the Jewish community, and moved to Acco to head its Jewish community.
