Discussion concerning the Czech early medieval society (tenth to twelfth century) will be presented on three casuistics, all showing how the ways of interpreting traces of the period may change the self–characterization of the society. (1) We shall discuss the ontological value of the “findings” of general comparative historiography: can we take analogical elements in several developmental lineages as of ontic nature, or do they represent a mere noetic effect? The question will be demonstrated by interpretative “introducing” of slavery into Czech history of that period. (2) We show how the Czech national community (via “its” historians) can restructure the space of its experience (i.e., the view of national history) according to its momentary needs: Whereas historians of the second half of nineteenth century interpreted the traces from Czech lands as an analogy to the situation in South Slavs, the generation of historians at the turn of the century coined the belief that since the tenth century the Czech history was already part of Western history. Thanks to such a shift of interpretation the image of the society considerably changed. (3) In the half of twentieth century, we witness yet another shift, when D. Třeštík interprets the traces per analogiam with the development in Poland.
