What were some of the major consequences of its decline, especially in western Europe and parts of the Mediterranean?
The consequences of the fall of the Western Roman Empire were many. The whole political body that had kept rule over the territory fell apart, and was replaced by many kingdoms.
Urbanization fell sharply, with some cities losing over 90% of their population, this in turn caused the ruralization of the economy, and the disappearance of most trade networks, which also increased poverty.
Feudalism would become the main economic system, replacing the slave-based economy of the Roman Empire.
