For 10 points, name this policy which was severely lacking in Iberia during the Spanish Inquisition.
In cases where this policy was lacking or nonexistent, the practice of taqiyya was often used for protection by concealing one's identity. Although this principle was advocated by Pope Alexander II, he sanctioned the War of Barbastro which ended in a massacre that defied it. This principle was upheld in the sixty-seven articles of the Capitulation of Granada regarding Moriscos, which was signed by Boabdil, but it was largely ignored after Cardinal Talavera's replacement by Cardinal Cisneros. Tomas de Torquemada was one of the chief opponents of this principle, and the Alhambra Decree was another step back in achieving this policy, because through it, Ferdinand and Isabella expelled Jews from their country.
