Final answer:
From 600 C.E. to 1450 C.E., Islam experienced changes in its social structure due to growth, new political structures, and religious divisions.
Step-by-step explanation:
During the period from 600 C.E. to 1450 C.E., there were several changes in the social structure of Islam. One significant change was the growth and spread of Islam, resulting in the expansion of Muslim communities across various regions. This led to the formation of diverse societies with a mix of different cultures and ethnicities.
Another change was the emergence of new political and social structures within the Islamic world. For example, the Mamluk Sultanate, which arose in Egypt during the 13th century, had a unique political and social organization that heavily relied on the military slave caste known as Mamluks.
Additionally, the role and influence of religion in Islamic societies transformed during this period. There were debates and divisions within the Muslim community concerning political and religious matters, leading to fragmentation along political and religious lines.
