The Islamic civilization affected the western civilization both scientifically (through the thousands of Islamic inventions and innovations) and morally (non racism, assuring women rights, non slavery, non discrimination and many other). Also Islam contributed to medieval Europe in areas as art, architecture, medicine, agriculture, music, language, and technology. The Western World which religion is mostly Christianity was threatened by Islam because the Islam had no trouble with the study of sciences, but in the case of Christianity, they disapprove totally the study of science at the time, if the Muslims would've taken more control in the Western, the community of Christians would have been reduced drastically.
