His legacy in the Islamic world was modest for geographical and intellectual reasons. In the west, Averroes was known for his extensive commentaries on Aristotle, many of which were translated into Latin and Hebrew. The translations of his work reawakened western European interest in Aristotle and Greek thinkers, an area of study that had been widely abandoned after the fall of the Roman Empire. His thoughts generated controversies in Latin Christendom and triggered a philosophical movement called Averroism based on his writings. His unity of the intellect thesis, proposing that all humans share the same intellect, became one of the most well-known and controversial Averroist doctrines in the west. His works were condemned by the Catholic Church in 1270 and 1277. Although weakened by condemnations and sustained critique from Thomas Aquinas, Latin Averroism continued to attract followers up to the sixteenth century.
