For fifty years since its establishment in the early 1890s, the Czechoslavic Ethnographical Society was the principal representative of the field in the area of present-day Czech Republic and Slovakia. It was the centre of folk culture research; no other comparably significant institution existed in this area. The history of the Czechoslavic Ethnographical Society is interwoven with interdisciplinary relationships.The reason is that the people, who had helped to create this association up to the 1930s, did not engage themselves fully and professionally in ethnography as their only or at least main discipline. It was due to the fact that there was sparsely any workplace where they could find any existential and scholarly background. Inspiration was thus brought in by people from different fields that had a close relationship to folk culture. The same went for principal bodies of this ethnographical institution which were formed by experts from different disciplines, including the membership base which often counted above a thousand people actively interested in folk culture. the leadership of the society endeavoured to actively employ these people, often experts from different disciplines or significant regional workers, in documentation of folk culture. This was apparent predominantly during preparation and compilation of ethnographical encyclopaedia in the 1920s and 1930s. Although it remained unfinished, it has been one of the chief projects of Czech ethnography in its history.
