In the early 7th century, Muhammad received divine revelations on the Arabian Peninsula, which within a generation of his death in 632 ignited one of history's most spectacular military expansions. The Arab armies, driven by the new faith of Islam, conquered the already exhausted Byzantine and Persian empires. Persia fell entirely, while Byzantium lost approximately two-thirds of its wealthiest territory—including Egypt, Syria, Palestine, and North Africa—in just a single decade. This rapid conquest established an Islamic caliphate that would stretch from the Iberian Peninsula to the Indus River by the 8th century, fundamentally reshaping the political and religious landscape of the world.

The Faith That Conquered the WorldAdded:
In the early 7th century, on the Arabian Peninsula, a merchant named Muhammad began receiving what he described as divine revelations.
Within a generation of his death in 632, those revelations had ignited one of the most spectacular military expansions in recorded history.
The Arab armies that burst out of Arabia were driven by something beyond ordinary military ambition.
They carried a new faith, Islam, that gave their conquests a cosmic significance. And they were fighting against empires already exhausted by decades of war with each other.
The Byzantine and Persian empires had been grinding each other to dust in an endless series of conflicts when the Arab armies arrived. Both were on their knees.
Persia fell entirely.
Byzantium lost Egypt, Syria, Palestine, and North Africa, roughly 2/3 of its wealthiest, most productive territory in the space of a single decade. The speed was staggering. The consequences were permanent.
By the 8th century, an Islamic caliphate stretched from the Iberian Peninsula
