The defeat of Islamic forces by Charles Martel at the Battle of Tours in 732 C.E. similarly curtailed the expansion of Islam into Western Europe. Together, these events contributed to the establishment of a boundary between the Islamic and Christian worlds, shaping the religious and cultural landscape of Europe for centuries to come. As a result, the spread of Islam was significantly limited in the territories surrounding the Mediterranean and into Europe.
