Final answer:
The spread of Arab control was accomplished through trade, conquest, and peaceful agreements. Islam spread through trade routes and the establishment of Islamic territories in North Africa and the Iberian Peninsula.
Step-by-step explanation:
The spread of Arab control was accomplished through trade and conquest. Islam diffused from Mecca and spread throughout the Middle East, Central Asia, and North Africa. The Arab conquests of North Africa and the Iberian Peninsula resulted in the expansion of Islamic territories.
The spread of Islam was facilitated by the establishment of trade routes, such as the Silk Road and the Sahara trade routes. These trade routes allowed for the exchange of goods and ideas, making the spread of Islam possible. Additionally, peaceful agreements and noninterference with the religious practices of subject populations also contributed to the spread of Arab control.
Overall, the spread of Arab control was a complex process influenced by various factors including trade, conquest, and peaceful agreements.
