Facing pressure in the years after the Disputation of Barcelona, despite the royal free speech guarantee that had covered the debate itself, Nachmanides emigrated from Catalonia to the Land of Israel in 1267, leaving behind the Girona community where he had practiced as rabbi, biblical commentator and physician. He arrived in Jerusalem to find the city's Jewish community absent, a documented consequence of the Crusades rather than a gradual decline, and reestablished both a community and a synagogue there.
That an established scholar already the author of a widely used biblical commentary combining rabbinic, philosophical and kabbalistic readings chose to rebuild a community from nothing in a city left without one, rather than remain in the settled position he held in Catalonia, marks his emigration as a documented act of institution building rather than a retirement from public life.
The sequence, a public debate that ended in surviving pressure at home followed by the physical rebuilding of Jerusalem's Jewish community abroad, ties two of Nachmanides's most consequential acts directly together, a compelled defense of Judaism in one country producing the reconstruction of a Jewish community in another only a few years later.
