The reasons for the growth of medieval cities include?

Medieval cities arose along trade routes and near rivers. Basically, the population was replenished by fugitive peasants. They left the feudal lord to create their own economy. In the cities there was no double tax if they were not subordinate to the feudal lord. This contributed to the development of craft workshops and market relations. Gradually, interest-earners, merchants, and hired workers appeared in the cities. Manufacturing developed there. People received income from such activities and could expand sales markets.
