The start of the younger Pre-Roman Iron Age was the time of a transformation of the communities residing in this region into a new civilizational quality that was radically different from the quality of the preceding period. In the interior of the continent, a certain “Celt fashion” could be noticed, which was manifested in adaptation of patterns of both material culture and, most likely, elements of Celtic rites. Its course appears to be the key to the understanding of the transformations taking place in Wielkopolska at the turn of the 2nd century B.C. In older literature, the origins of the changes taking place at that time were linked to the transformation of the community of the Pomeranian (Wejcherowo-Krotoszyn) culture as a result of influence of strong Celtic currents that resulted in formation of a new group typical of cultural currents of the younger Pre-Roman Iron Age, namely of the Przeworsk culture. Currently we know that the issue is not quite as simple and unequivocal.
