This volume compiles the contributions at the International Conference of the same name, which was held at Leibniz University Hanover in June 2021. The conference was planned by the collaborative project "Provenance Research on Non-European Collections and Ethnology in Lower Saxony" (PAESE), coordinated at the State Museum Hanover. The aim was to bring together actors from different perspectives to discuss questions, methods and (preliminary) results in the field of provenance research on collections from colonial contexts.
