Kabbalistic Diagram

Carrying books and knowledge, itinerant rabbis and scholars traveled between communities, facilitating cultural exchange. 

Kabbalah spread widely after the Spanish expulsion. The Zohar's printing in Italy, Safed's influential kabbalistic center, and Shabbetai Tzvi's messianic movement popularized mystical ideas across Jewish communities.

Ashkenazim, Sephardim, and Marranos encountered each other in Italian cities, developing community structures that later influenced Jewish communal organization throughout the western world.
