This dissertation represents the research of the identity of the 5th and 6th centuries in the area of the former Roman provinces (Savia, Sirmiensis, Dalmatia), that is, the research of the area of southern Pannonia and Dalmatia, with a special emphasis on the territory of the Republic of Croatia. Questions of identity, largely unexplored during the turbulent period of the great migration of peoples during the aforementioned two centuries, in archeology are most often based on opinions and conclusions about the ethnic identities of the newly settled population in the territory of the mentioned Roman provinces. The dissertation brings a view of identity research in general and is not limited exclusively to ethnic identity, but the problem of looking in-depth, following the sociological changes of individuals and groups within society, which is inevitably changing at a high speed due to the coexistence of the newly settled and indigenous population. The question to what extent objects of archaeological material culture can unequivocally testify to the identity of the bearer of material culture is considered. In this way, the dissertation presents interesting social phenomena that change the ethnic, social, economic and economic profile of the mentioned area. With an interdisciplinary approach to the scientific research of the non-Roman population of southern Pannonia and Dalmatia, the aforementioned phenomena can be more thoroughly observed, which in archeology can be reflected in the material culture that this population left in the cultivated areas during the 5th and 6th centuries. Certain, already existing, interpretations of archaeological material need to be re-examined and the maximum amount of possible data that the subject can provide with regard to the above categories should be exhausted. The research approach is inevitably interdisciplinary and, along with archaeology, it assumes the inclusion of other scientific disciplines that complement the archaeological conclusions. Special consideration is given to the relationship between written sources and researched objects of material culture, in terms of the relevant information we receive from one side and the other. The detailed study and presentation of most of the researched and published objects of the material culture of the non-Roman population in one place facilitate the work of researchers who, in the future, will interestingly delve into this period. The interpretation of the findings through the textual and pictorial part of the reconstruction opens this topic for further discussion about the possibilities of interpreting the identity of the non-Roman population of southern Pannonia and Dalmatia during the 5th and 6th centuries. The period of the mentioned two centuries marks the turbulences that took place at that time in the territory of the Roman Empire, which meant radical changes and the foundation of the establishment of Europe as we know it today.
