The connections between Slavic agricultural traditions and the signs of the development of civilizations from the Stone Age and the Copper-Stone Age are indisputable. The Slavs are mostly farmers, but their land cultivation methods are not sufficient enough to feed large communities. For this reason, they live in small tribal settlements. Their fragmented and independent way of life has for centuries prevented them from developing a centralised state form and sovereign power. As a result, the frequent enemy raids required constant migration and impeded their rather sedentary lifestyle and development of significant material culture and architecture.
The Slavs reached the peak of their power by the 6th - 7th centuries as a result of gradual consolidation and social development, especially in the territories of Eastern Europe. Their subsequent existence as an ethnic group in the Balkans is closely linked to their unity with the Proto-Bulgarians and the unification of the Bulgarian state.
