This paper deals with the interpretation of early Slavs through the prism of their ethnicity, language nad archaeological cultures tied to them. The primary focus of this paper is Florin Curta's approach, he strongly critiscises earlier teories and interpretations. He present his own interpretations of the same historical materials that were used in earlier teories. Parallel to this the paper presents the approach, teories and interpretations of other modern historians, such as Barford and Pleterski. Other than with scientists views this paper deals with question of slavic identity or ethinicity and about the posibility of discussion about wider awareness or common identity in that period. The subject of slavic language and the question of modern spread of slavic languages is also addressed. The question is raiesd about interpretation of archaeological cultures attributed to Slavs and the likeliness of that attribution. The question of trustworthiness of byzantine authors is also raised, that question is important because byzantine authors used to be the primary historical source for scientists in the formation of their theories.
