In the Alhambra Decree, Isabella of Castile and Fernando of Aragon order all Jews to leave their kingdoms by 31 July 1492. This was in spite of them guaranteeing religious freedom in the Treaty of Granada, signed in 1491 between Emir Muhammad XII and Isabella of Castile. However, the Fall of Granada on 2 January 1492 changed everything.
While under Moorish rule Jews and Christians had been free to practice their religion and learning and trade had flourished, this changed dramatically with the Alhambra Decree and a time of religious persecution and much suffering began.
