The rise of Islam and the spread of the world you once knew was shameful, and the food was very poor, people are fighting several breads. The political class is fighting each other to take care of others. Children are hanging around on the street and are appealing for work to feed their dead hungry belly. This is not a horror movie scene but a reality that began in the post classical era. In such a difficult time, people turned to higher powers, which led to religious prosperity.
Muslim is one of the most popular religions in the world, with an estimated 5 billion fans, one of the second oldest religions after Christianity. The rise and expansion of Islam started in the early 7th century C. E. founded by the Arab prophet Muhammad. The roots of Islam are traditions of Judaism and Christianity, but there are also some changes. The main change is the revelation of God that Muhammad claimed, and he is considered more than just a religious teacher. He considers the group of believers as a thorough exercise aimed at promoting the true faith of religion.
The rise and expansion of Islam has also resulted in increased trade. Islam is very gentle to the life of the business and the establishment of the Arab Empire provides a stage for the Muslim merchants' engines. Middle Eastern gold and silver moved to South India and established a trader community. Slave trade from East Africa was inspired. The expansion of Islam promoted a broad transformation that created international marine culture and promoted commerce. I think you should mention China's resurgence, and especially mention it during the Tang and Song dynasty (618-1279). In addition, China became the first consumer of the Indian Ocean network, not the product supplier. Certain technical advances are larger ship and magnetic compass
A significant change in the Mediterranean culture is the rise of Islam. It rapidly spread throughout the Mediterranean region of Africa. And it was once a variety of religions. Muslims are not common in most of the European Mediterranean, but it crosses Spain at 711 C. E. Before Spain became a Christian, there were still Christians in this area, but Muslims were more common.
