This paper reviews archaeological research on the transmission of writing knowledge between literate and pre-literate societies. It proposes the use of productive approaches, such as cultural epidemiology and cultural attraction theory (CAT). The case study focuses on East-Central Europe and discusses the role of writing in the construction of social group identity and the transition from local communities with a prehistoric mindset to a historically acting society during the first millennium AD. The study collects relevant archaeological records of Early Mediaeval writing and explains them using reflective archaeology. It is shown that interactions between literate and pre-literate societies are highly complex social processes that function not only at the cultural and cognitive levels of individuals but also among larger groups of people. By combining cultural attraction theory with empirical archaeological data, this study formulates a conclusive explanation for the introduction of writing among Europe's Slavic-speaking population.
