The presence of the Vikings and their trade networks contributed to the urbanization process as these towns grew in prominence due to their strategic locations and economic activities.

Similarly, while there were adjustments in agricultural practices, particularly as a result of raids and shifting land use, local agriculture did not uniformly decline.
