Balthazar Mendez de Loyola, born Muhammed El Attaz (1631 in Fez, Morocco – c. 15 September 1667, in Madrid, Spain) was a Moroccan prince converted to Catholicism. He became a Jesuit priest and devoted himself to the evangelization of Muslims.

Muhammed came from a noble Muslim family, from the Saadi dynasty. In 1654, he went on pilgrimage to Mecca. El Attaz was captured and all his company by the Christian fleet of Balthazar Mandols before the Cap Bon. Captive in Malta, he was released in 1656, once paid his ransom. He crossed at that time a spiritual crisis and converted to Catholicism. Muhammad then settled in the palace of Mandols, Malta and there receives the baptism on July 31, 1656, under the name of Balthazar of Loyola, in homage to its host and sponsor Ignatius of Loyola.^[1] He then walked on the Italian ports to try to evangelize the captives "Moorish" held by the Christian armies.^[2]

In 1657, Loyola entered in the novitiate of the Jesuits in Messina, in Sicily . He received the priestly ordination on December 27, 1663, and came to Lisbon to become a missionary in the East Indies. He died on the way to Madrid, around September 15, 1667.^[3]

Sami Lakmahri, Moroccan journalist of monthly Zamane, said: "In the 17th century, on both sides, forced conversions are legion. [...] Can we think that Mohammed El Attaz in reality only seeked to ease his captive condition or seek liberation? The ecclesiastical career following the conversion of El Attaz allows room for doubt. Balthazar is not just a Christian. His status of out-of-standard man of faith can not be achieved without a extreme religious devotion".^[2]

According to Sami Lakmahri, "in terms of propaganda, notable Christians can not imagine a better story. A Muslim prince, pious and wise, chose to join the cause of Jesus Christ. The history of this incredible conversion abounds in Western literature. Writings of historians, clerics and even plays, all types have taken over the Balthazar story. The goal is to make the Moroccan a significant religious figure of his time. A proof of the basis of the struggle of Christians against infidel "Mohammedans". If even the highest Muslim leaders embrace the Christian faith, his superiority while longer is out of doubt".^[2] Pedro Calderón de la Barca wrote about Loyola in 1668, shortly after his death, probably in order to support his trial beatification.^[4]
