The late Neolithic of the Vinkovci area was marked by the newly emerged cultural phenomenon - Sopot Culture. As an autochthonous phenomenon based on the substrate of Starčevo and the influences of the Vinča culture, it contains some elements of the previous culture, such as decoration techniques and the topography of the settlement, while taking over new techniques of pottery and decoration from Vinča. With its expansion in the classical phase, in the territories of northern Croatia and across river Drava into the area of Transdanubia, it influences the creation of regional types. The problem with culture itself is in its absolute dating, which is not completely clear to this day and is a matter of debate. A major problem is the insufficient exploration of a large number of archaeological sites. The eponymous site of Sopot is distinguished by long-term research on the basis of which the cultural developments based on ceramic findings and the "urbanization" of the settlement are known. Earlier research on tell, Otok, Privlaka and Orolik sites helped define the culture, while new research on single-layer sites in Ervenica and Pjeskana deepened the understanding of culture.
