The burial sites scattered over the entire area of the canton Basel-Stadt represent the main archaeological source for the Early Middle Ages in Basel. Due to the great diversity in the grave goods and based on the interpretation of the antique written sources, the material has hitherto been interpreted ethnically, since the subdivision of the early medieval population into Romans, Alamans, Danubian-Suebi and Franks formed a basis for the interpretation. A new evaluation of the archaeological material based on the examination and reconstruction of networks using the distribution of brooch and belt types shall thus introduce new perspectives in the traditional narratives. This study showed that most of the interactions were locally or regionally determined and were focused on the High and Upper Rhine as well as in south-western Germany. Relations to the north – especially along the River Rhine – as well as with the Burgundian area also played an important role. Differences in the distribution (especially to the west or to the east) seem to be related not only to the chronology, but also specifically to the location of the burial sites on different transport and communication axes. Widespread influences appear to be decreasing over time, although these may be overlooked due to changes in burial practices.

This upload corresponds to the online and free available supplements related to the article "Beziehungsgeflechte im frühen Mittelalter – Eine Fallstudie aus Basel" published by Margaux L. C. Depaermentier and Susanne Brather-Walter in ZAM - Zeitschrift für Archäologie des Mittelalters (edited by Sebastian Brather, Ulrich Müller, and Heiko Steuer). The csv file lists the sites (and their coordinates) where the analysed brooch and belt buckle types, which are represented in Basel in the early Middle Ages, are attested. For each site, the corresponding brooch or belt buckle type as well as the chronological frame has been specified. The lists of the individual burials corresponding to the sites are available in the ZAM article. Based on this csv file, the distribution of each brooch and belt buckle type has been mapped and modelled with a Kernel Density Estimation (KDE). Each TIFF file named after a brooch or belt buckle type show the corresponding map. Finally, this upload includes the high resolution figures published in the ZAM. These are the TIFF files names under Abb_1 to Abb_18.
