Step 1 : Introduction to the question "Which warrior queen, at the time much admired by the Catholic Church, expelled the remaining Jews and Muslims from her country?"
...Isabella, Queen of Castile in her own right, married King Ferdinand of Aragon. While best known for funding Columbus's expeditions to the New World, the darker side to her reign saw her beginning the Inquisition in 1478 to persecute those not of the Catholic faith. In 1492, Isabella and Ferdinand expelled all the Jews and Muslims in Spain who refused to convert to Catholicism. For their work, Pope Alexander VI named Isabella and Ferdinand "The Catholic Monarchs". Her youngest child, Catherine of Aragon, went on to marry Henry VIII and continued to remain firm in her mother's faith after Henry broke from the Catholic Church. Juana la Loca was Isabella and Ferdinand's daughter who became Queen of Castile after her mother's death. Mary I of England was Isabella's granddaughter through Catherine of Aragon and Henry VIII. She was a dedicated Catholic, but her persecutions of Protestants earned her the nickname "Bloody Mary". Maria of Spain was the great-granddaughter of Isabella and was Queen of Spain with her husband Maximilian II, Holy Roman Emperor.
