Islam originated in the 7th century CE with the Prophet Muhammad, who is considered the last prophet in Islam. He received divine revelations that were later compiled into the Quran. The religion began in Mecca and Medina, where Muhammad preached and gained followers. After his death, the religion expanded rapidly through military conquests and trade. The early Islamic caliphates established vast empires that facilitated the spread of Islam across North Africa, the Middle East, and into Europe and Asia. The combination of military expansion, trade, and the appeal of Islamic teachings contributed to its growth and establishment as a major world religion.
