In Poljica were, as well as in the whole of Dalmatia, during two centuries (16th and 17th century.) happened confrontations of three powers: the Ottoman Empire, the Venetian Republic and the Habsburg Monarchy. The confrontations were characterized by changing borders, the constant uncertainty and economic underdevelopment. The migration processes, which took place in the Early modern period, in Poljica did not lead to drastic demographic change. Comparing the works of other authors and analysis of the "state of soul" we came to conclusion that immigration of Vlach population and emigration of the local population in neighboring areas, held a permanent population in Poljica without large fluctuations in numbers.
