What is "krici"

The Kriči were, according to tradition, an "older" people that inhabited an area somewhere by the Tara river in what is today northern Montenegro. Kriči (and similar names) has been periodically mentioned in historical sources, geographical and ethnological literature. Their ethnic affiliation is unknown from historical sources, although tradition points that they were an old population, deemed Vlachs ( Romanized Illyrian) in theories found in anthropological studies. They, as other pre-Slavic tribes in the region, eventually assimilated into the Serb ethnos. Some toponyms in Montenegro and surnames are derived from the name of this tribe.
