How did cairo’s status as a trade city increase interconnectedness across afroeurasia?

Cairo increased interconnectedness because it helped traders to bring products from Africa and India and further East to Europe.  These traders could also return with European goods and thus far away regions started becoming more interconnected.

Explanation:

Cairo was a very important city in Afroeurasia and it was a center for trade. In the 14th and 15th centuries, merchants and traders would come to the city by land and sea and it was a center of the Islamic world. Cairo was connected to the Indian Ocean through the Nile, the Red Sea, and the Mediterranean Sea. This was the most important trade route from Europe at the time. The Bubonic Plague was also said to have traveled along this same route as it crippled Cairo and Europe's major port cities.
