The Edict of Expulsion refers to the decree issued by the Catholic Monarchs, Ferdinand II of Aragon and Isabella I of Castile, in 1492. This edict ordered the expulsion of all Jews from Spain who refused to convert to Christianity. It was part of a broader effort to unify the country under a single religion following the completion of the Reconquista. The expulsion had significant social and economic impacts, as many Jews were prominent in trade, finance, and various professions. The decree led to the migration of thousands of Jews to other regions, including Portugal, North Africa, and the Ottoman Empire, where they sought refuge and continued their cultural practices.
