An Islamic State
In 630 A.D., the people who lived in Makkah attacked Muhammad and his people in an attempt to destroy them. The Muslims were not only able to defend themselves against attack, but in the same year were able to overthrow and conquer Makkah.
Many tribes throughout the Arabian Peninsula saw this as a sign of Allah’s power. By 631 A.D., Muhammad was recognized throughout the region as the prophet of God. As Allah’s prophet, Muhammad was then easily able to conquer the entire Arabian Peninsula with little opposition.
Muhammad set up a strong central government, whose capital was in Madinah. He destroyed all the idols that were in Kaaba, and instead established Kaaba as the center of Muslim worship. Thus, Makkah became the religious capital of this Islamic nation.
