Ibn Rushd (; April 14, 1126 – December 10, 1198), full name , 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.
Ibn Rushd was a defender of Aristotelian philosophy against Ash'ari theologians led by Al-Ghazali. Although highly regarded as a legal scholar of the Maliki school of Islamic law, Ibn Rushd's philosophical ideas were considered controversial in Ash'arite Muslim circles. Whereas al-Ghazali believed that any individual act of a natural phenomenon occurred only because God willed it to happen, Ibn Rushd insisted phenomena followed natural laws that God created.
Ibn Rushd had a greater impact on Christian Europe: he has been described as the "founding father of secular thought in Western Europe" and was known by the sobriquet the Commentator for his detailed emendations to Aristotle. Latin translations of Ibn Rushd's work led the way to the popularization of Aristotle.
