These events took place between 622 and 750, first involving the establishment of a new unified polity in the Arabian Peninsula, then leading to a Muslim Empire which stretched from central Asia to North Africa and was one of the largest the world has ever seen.

Previously, various tribal groups vied for regional supremacy and Muhammad’s political, and religious leadership was the vehicle that facilitated the integration of Arabian tribal areas, and thus allowed the conquest to happen through the formation of a unified Arab army. Lapidus states that previously “the leading
