The development of landscapes of the central part of the Middle-Volga region in the last 2500 years was a discontinuous process of the explosive growth of population and land utilization alternating with stages of depopulation and desolation. The periods of depopulation and transitions of cultures occurred at similar times to climate changes. Some cultures were associated with distinct climatic episodes, such as the association of the Dark Ages Cold Period with Hun, post Hun, Heraldic, and Khasarian times, and the Medival Warm Period with the time of Volga Bulgaria. A combination of archaeological and paleoecological analyses allowed us to reconstruct a sequence of landscape and land use changes in relation to the historical development of the region. The first millennium CE was a time of major changes in population, agricultural technologies, social structure, and settlement patterns in the forest-steppe zone. The Middle Volga region underwent a transition from a non-populated, mainly forested landscape of first centuries CE to a highly deforested agricultural landscape of the Volga Bulgarian state by the 11th century CE. Within several centuries, the landscape was transformed by shifting cultivation, wood and ore extraction, and the formation and expansion of pastures and road networks. The process of deforestation in the region was facilitated by the relatively warm climates of the Medieval Warm Period.
