AbstractIn various prehistoric periods, the territory of Vojvodina became the target of the migration of steppe communities with eastern origins. The oldest of these movements are dated to the late Eneolithic and the beginning of the Early Bronze Age. There are at least two stages among them: I – dated to the end of the fourth millennium BC / beginning of the third millennium BC and II – dated from 3000 to 2600 BC and combined with the communities of the classical phase of the Yamnaya culture. The data documenting these processes have been relatively poor so far – in comparison with the neighboring regions of Bulgaria, Romania and Hungary. A big drawback was the small number of systematically excavated mounds, providing comprehensive data on the funeral ritual of steppe communities. This poor database has been slightly enriched as a result of the design of the National Science Centre (Cracow, Poland) entitled “Danubian route of the Yamnaya culture”. Its effect was to examine the first two barrows located on the territory of Bačka – the western region of Vojvodina. Currently, these burial mounds are the westernmost points on the map of the cemeteries of the Yamnaya culture complex. Radiocarbon dates obtained for new finds, as well as for archival materials, allow specifying two stages of use of cemeteries of Yamnaya culture: I – around 3000–2900 BC and II – around 2800–2600 BC. Among the finds from Banat, there were also few materials coming probably from the older period, corresponding to the classical phase of Baden – Coţofeni I–II. The enigmatic nature of these discoveries, however, does not allow to specify their dating as well as cultural dependencies.
