The Treaty of Granada (1491), as negotiated at the final surrender of the Muslim state of Al-Andalus, clearly mandated protection of religious rights, but this was reversed just over 3 months later by the Alhambra Decree of March 31, 1492. Under the new Decree, approximately 40,000 Jews were expelled from Spain with only their personal possessions. Approximately 50,000 other Jews received a Christian baptism to remain in Spain. Many of them, derogatorily dubbed "Marranos" by the Old Christian majority, secretly kept some of their Jewish traditions. They were among the chief targets of the Inquisition, but it also pursued anyone who would criticize it.
