How has the prehistoric relationship between Finland and Estonia been used as a means to construct Finnish or Estonian identity in these countries? Have these neighbours represented similarity or difference to one another? On what kind of premises have interpretations been based?

This paper presents an overview of the main trends of development from the 1880s to the1940s concentrating mainly on general publications of prehistory. The methodological framework of the study consists of archaeology, the history of ideas and cultural semiotics.
