Step-by-step explanation:
Baghdad was at the crossroads of trade routes that linked Africa, Europe, and Asia. During ancient times, these routes included the trans-Saharan trade routes which were essential in connecting the markets and products of North and West Africa to the Middle East and Europe. They allowed not only for the trade of commodities like gold, salt, and spices but also for the exchange of cultural influences, including the spread of religion and language. The Saharan trade routes led to cosmopolitan settlements and trade centers such as Awdaghost, Sijilmasa, and Djenné, which were crucial in the diffusion of cultural aspects and commerce.
Moreover, the Islamic world was interconnected by a complex network of land and sea routes, with Muslim merchants trading from Indonesia to East Africa, and central Asia to China. Baghdad, being a pivotal point within these networks, facilitated the movement of goods as well as the flow of innovations, ideas, and religious beliefs across vast distances. This interconnected trade system shaped the early global economies and fostered the further spread of Islamic culture.
