"The Disputation at Barcelona" was a pivotal event in 1263 where Rabbi Moses ben Nachman, a prominent Jewish scholar, engaged in a formal debate with Pablo Christiani, a Jewish convert to Christianity, in the court of King James I of Aragon. The aim was to prove the superiority of Christianity and convert Jews. Nachmanides defended Judaism skillfully, but despite his efforts, Christiani was declared the winner. Nachmanides faced persecution and was forced to flee Spain. However, his writings about the disputation remain significant in the history of Jewish-Christian relations.
