Final answer:
Muslim traders impacted Sub-Saharan Africa economically by introducing new crops, which helped diversify and stimulate agricultural production. This was part of the broader influence of Islam, which encouraged commercial and cultural exchange across the region, contributing to economic growth.
Step-by-step explanation:
One economic impact Muslim traders had on Sub-Saharan Africa was the introduction of new crops. The spread of Islam facilitated trans-Saharan trade, with Muslim traders establishing extensive networks across the desert. This not only aided in the spread of their religion but also supported agricultural advancements through the introduction of new crops, which in turn could support economic growth by diversifying and increasing food production. Through trade, Islam provided a unifying set of customs and principles which encouraged commercial exchange and cooperation among disparate groups, therefore fostering a conducive environment for economic activity, including agriculture.
Furthermore, as trade routes developed, centers of learning, such as Timbuktu, became connected to the wider Islamic world, enhancing cultural and technological exchange. Islamic law and shared language eased the process of trading and stimulated economic activity across the region. The influx of new agricultural technologies and practices, along with increased commercial activity, had a lasting economic impact on Sub-Saharan Africa.
