Craniometric relationships among medieval Central European populations: Implications for Croat migration and expansion

Aim. Principal components analysis (PCA) and discriminant function analysis of craniometric data from Central and South-east European medieval archaeological sites were used to determine the ethnic composition of the early medieval Croats, the location from which they migrated to the east coast of the Adriatic, and to separate early medieval Croats from Bijelo brdo culture members. Methods. Mean male values for 8 cranial measurements from 39 European and 5 Iranian sites were analyzed by PCA. Raw data for 17 cranial measurements for 103 female and 112 male skulls were used to develop discriminant functions. Results. The scatter - plot of the analyzed sites on the first 2 principal components showed a pattern of intergroup relationships consistent with geographical and archaeological information not included in the data set. The first 2 principal components separated the sites into 4 distinct clusters: Avaroslav sites west of the Danube, Avaroslav sites east of the Danube, Bijelo brdo sites, and Polish sites. All early medieval Croat sites were located in the cluster of Polish sites. Two discriminant functions successfully differentiated between early medieval Croats and Bijelo brdo members. Overall accuracies were high - 89.3% for males, and 97.1% for females. Conclusion. Results of the PCA suggest that early medieval Croats were of Slavic ancestry, and that at one time they shared a common homeland with medieval Poles. Application of unstandardized discriminant function coefficients to unclassified crania from 18 sites showed an expansion of early medieval Croats into continental Croatia during the 10th to 13th centuries.
