In the crusades what did Muslims learn from christians?

Answer 1

Christians primarily learned of spices, cuisine, articles worth trading, and intellectual arts (like philosophy, science, math, music, and visual arts).
The Europeans did not learn tolerance or equal treatment from the Muslims as a result of the Crusades. Regardless of whether Muslims actually had such policies (which is itself questionable), the more striking problem with this assertion is that it is clear that Europeans did not learn these or similar values by the end of the Crusades (from anybody). The Crusades ended in the mid-1200s, preceding the Spanish Inquisition, the Thirty Years War, numerous unequal laws based on ethnicity or religion, and, of course, the Barbarity of the Enslavement of the African Peoples. Additionally, even most Muslims claim that European Imperialism was based on a fundamental belief of European Cultural and Racial Supremacy. European tolerance and equal rights derives from the Enlightenment Period (1600s) and from the traumas (like the Thirty Years War) that resulted from the inability to accept different religions and beliefs.
