Final answer:
Islam in Africa spread mostly through trade, cultural exchange, and as a part of the trans-Saharan trade network, which had greater influence than the spread by military conquests. The shared language and customs among Muslim traders facilitated this spread, integrating Islam into diverse African cultures.
Step-by-step explanation:
The spread of Islam in Africa is characterized by both peaceful means, such as trade and cultural exchange, and at times, through military conquests. However, it is important to note that Islam's impact through peaceful methods was more significant when it came to the widespread adoption of the religion across Africa. Trans-Saharan trade routes played a major role in the dissemination of Islamic beliefs, leading to the gradual acceptance and integration of Islam into various African societies, particularly in West and East Africa.
In regions like Ancient Mali, Islam became firmly established through interactions with Muslim traders rather than by force, highlighting the importance of economic and social relationships in the spread of Islam. The shared language of Arabic and Islamic customs facilitated further unity and trust among traders, which in turn extended the reach of Islam.
Military conquest did play a role in the initial spread of Islam in parts of Africa, but the religion's lasting influence was more profoundly felt through peaceful integration with existing cultural and economic systems.
