The formation and way of life of medieval communities was conditioned by social and natural factors, once isolated, and most often intertwined. Social factors can include anything that came out as a result of organised work of people in a community (rulers, i.e. their government with a developed network of organs). The natural factors that predominantly influenced the type of medieval communities were primarily relief and climate. These two factors were usually closely related and mutually conditioned. The types of communities and living conditions in them depended on the relief, since natural conditions provided opportunities for specific type of human communities to be characteristic of areas with certain geographical properties. Considering the natural living conditions, depending on the natural environment, three types of human habitats can be identified in the area of medieval Montenegro: coastal, continental lowland and mountainous. This classification is conditional and is based primarily on altitude and some features of the relief where the habitats existed. Each of these habitats was certainly socially shaped by the human community. Each of them was specific in its own way, very often determined by natural factors.
