The expansion of Islam began in the 7th century after the death of the Prophet Muhammad. Following his teachings, Muslim armies rapidly spread the faith across the Arabian Peninsula and into regions like North Africa, Spain, and parts of Asia. This expansion was driven by a combination of military conquests, trade, and the appeal of Islam's message. As Islam spread, it influenced various cultures and societies, leading to the establishment of vast empires, such as the Umayyad and Abbasid caliphates. These empires facilitated the exchange of knowledge, art, and technology, contributing to a rich cultural heritage that shaped the world in significant ways.
