The 1960s saw an extraordinary development of international cooperation within European ethnology. The reason were favourable international political circumstances, advanced research work of the progressive generation of ethnographers as well as institutional and paradigm establishment of the European comparative ethnology (Ethnologia Europaea), which was suggested mainly by Sigurd Erixon and his collaborators. Even the generation of exceptional personalities of Czechoslovak (or Czech and Slovak) ethnography participated in the work on large-scale projects; they also were members of supranational research teams and organizations. A plethora of internationally anchored research dealt with transport, grain cultivation and livestock rearing - i.e. themes relating to the agrarian ethnography, whereby it was the SIEF Commission or History and Development of European Agriculture that carried a lot of weight in the coordination of the above research in the late 1960s. The contribution analyses the background and work of the Commission, the results of international projects organised by it, and the influence of the
large-scale research on the development and thematic targets of Czech ethnography in the 1960s through 1980s.
