Since Isabella an Ferdinand emphasized Catholicism, they forced all the non-Catholics out of Spain which started the Spanish Inquisition. She and Ferdinand started the Spanish Inquisition in 1480. People who didn't want to convert to Catholicism had to leave Spain by June 1,1492. She and Ferdinand wanted to unify Spain to make it a Catholic country. Since she was a strong supporter of Catholicism, she made all the non- Catholics leave Granada, Spain then Castile, Spain. Jew and Muslim Spaniards were removed from Castile if they didn't convert to Catholicism. If they didn't move out, they would be punished.
