The sixteenth century for the Split commune is one of the hardest historical periods. With the arrival of the Ottomans, the Split area is experiencing major political, economic and demographic changes. The Ottomans are constantly attacking the territory of Split, hindering the normal functioning of life in the Split district. The topographic image of the Split area changes and significant migrations occur within the district. The border problems, which existed before the Ottomans, are now experiencing the culmination. The boundary becomes permeable and areas of disputed and nobody`s land occur. After the Cyprus War, the Split district was divided on two parts leaving only oversea communication. The population, due to the loss of a large number of land holdings, as well as the lower land rent, started to cultivate land on ottoman side of border. The Split commune loses strategically important saltworks, and even more important mills, which leads it to dependent position. Aristocracy of Split commune, due to closing Great council and losing portions of land, weakens economically and biologically. This opens space for commoners to confrontate them. Particularly emphasized are the newly formed „citizens“, composed of richer and more prominent commoners. The Split nobility in 1596. conquered Klis, but because of Venetian obstruction they lost it the same year.
