1. West Africa before the Portuguese was a thriving region. There were several kingdoms that were very wealthy, and the main reason for that was that they had lot of natural resources and the trade. These kingdoms were conducting the majority of the trade between Northern Africa and sub-Saharan Africa, so they were able to gain lot of wealth from the countless goods that were traded through their territories.
2. Europe after the Crusades experienced a real ''boom'' in the trade, thus in its economy as well. Through the Crusades, the Europeans were introduced to lot of goods from the Middle East and the rest of Asia.

The majority of the people were still mostly producing goods just about enough to sustain themselves, so they were not engaging into a large scale trade with places further away.
