Answer:
Germanic invasions, the reduction of agricultural production, the end of trade routes and the reduction of population.
Explanation:
The co-commerce of the ancient Rome presented itself as a very promising sector that generated a lot of wealth for the empire. However, this accumulation of riches, attracted the ambition of the Germanic peoples who decided to make invasions to Rome and stipulated great commercial difficulties.
First, the Germans damaged the trade routes, causing them to end. This greatly damaged the Roman empire, preventing the products from being sold in various locations. The Germans also made several looting of the warehouses, destroying the agricultural production that would be commercialized. Last, but not least, the population reduction brought about by the Germanic invasions reduced the production of all products sold in Rome, causing a major collapse in the productive and commercial sector.
