During the early Middle Ages, only a few towns existed primarily due to the decline of the Roman Empire, which led to decreased trade and economic stability. The rural economy became dominant, with most people living in isolated agricultural communities. Additionally, invasions and instability made urban life less appealing and unsafe, further hindering the growth of towns. As a result, urban centers were limited, often serving as local trade hubs or administrative centers rather than thriving cities.
