Commerce is a human activity practiced by societies since the beginning of evolution. Exchanges were made between products negotiated by entire communities at first. They began to be based on a common currency and practiced individually over time, from family to family. In one way or another, this activity is a characteristic of civilization and even influences our territorial organization. Historically practiced in outdoor spaces, commercial activity defined many spatial configurations.
At the root of the commercial practices we know, we had bartering, which was born from the excess production for subsistence. Another item would be traded for this excess by a neighboring community. In the past, barter included food, fabrics and spices and was practiced both within the same territory and through travelers who brought new products through the roads that connected small settlements. With the densification of these clusters, commercial activity became a spatial reference for the territory.
