Averroes was a philosopher under which philosophical movements  such as Aristotelianism and the 13th-century philosophical movement  came into play in what other religions beside Islam?
Averroes Ibn Rushd (Arabic: ‎ ‎ ; 14 April 1126 – 10 December 1198), full name (Arabic: أبو الوليد محمد ابن احمد ابن رشد‎ , "ʾAbū l-Walīd Muḥammad Ibn ʾAḥmad Ibn Rushd " ‎ ), often Latinized as Averroes ( ), was a medieval Andalusian polymath. He wrote on logic, Aristotelian and Islamic philosophy, theology, the Maliki school of Islamic jurisprudence, psychology, political and Andalusian classical music theory, geography, mathematics, and the mediæval sciences of medicine, astronomy, physics, and celestial mechanics. Ibn Rushd was born in Córdoba, Al Andalus (present-day Spain), and died at Marrakesh in present-day Morocco. His body was interred in his family tomb at Córdoba. The 13th-century philosophical movement in Latin Christian and Jewish tradition based on Ibn Rushd's work is called Averroism.
Álvaro of Córdoba Paulus Alvarus (also known as Paul Alvarus, Paul Albar, Alvaró de Córdoba), c. 800 – 861 CE, was a ninth-century Mozarab scholar, poet, and theologian who lived in Southern Iberia during the period of Muslim rule. He is most notable for his writings around the time of a rising high civilization of Islam, owing to the Caliph's efforts. He also wrote the "Vita Eulogii" (‘The Life of Eulogius’), a biography of his close friend and fellow theologian Saint Eulogius of Cordoba. Although Christians living in Córdoba and the rest of Muslim Iberia during his time lived under relative religious freedom, Alvarus was amongst the Christians who perceived the many restrictions on the practice of their faith to be unacceptable persecution; they regarded with extreme scorn Christians who participated in the Muslim government, converted to Islam, or simply concealed their true beliefs. As a result of these religious tensions Alvarus’s writings are characterized by contempt of all things Muslim and he considered Muhammed to have been the precursor to the Antichrist.
