Situația etno-demografică și politică din zona sudică a spațiului Pruto-Nistrean în secolele VIII-XI d. Hr.
As a result of the archeological investigations undertaken in the Carpathian-Dniester regions, the dynamics of the dwelling from the 6th -11th centuries AD could be quite well known. It was found that the sedentary local population preferred the areas of plateaus and hilly plains covered with forests, which were the most suitable for the establishment of settlements of farmers and craftsmen. The steppe areas, such as the one in the south of the region between the Prut and the Dniester called Bugeac, were especially preferred by nomads. During the VI-VII centuries, no settlements of the sedentary population were attested in this area. Surprisingly, during the VIII-IX and X-XI centuries, despite the numerous presence of nomads, a series of settlements belonging to the sedentary population were discovered. Their presence here could be due either to their dislocation from the central areas of the Prut-Dniester area, as a result of threats by migrant populations, or to the deportation by the Bulgarians of some of the Byzantine prisoners taken during the siege of Adrianople in 813. Their repatriation by the Byzantine fleet in 837 was probably only partially done, with the rest continuing to live here until the beginning of the 11th century. Probably these could be the so-called Tivars, which were also used as translators between the local population and the nomads from Bugeac. In the following period, in the XII-XIII centuries, in the southern part of the mentioned area, no settlements of the sedentary population were attested, but only vestiges of the nomads.
