This anthology is the result of an international workshop with the aim to initiate new discussions and new research on cultural heritage - contested as well as uncontested. The workshop was held at the Department of Society, Culture and Identity at Malmö University, in October 2022. Contested heritage, sometimes also referred to as "dissonant heritage" or "difficult heritage" has been discussed, explored and studied by cultural heritage scholars from various disciplines over the last two decades. However, there is still limited knowledge about what contested or dissonant heritage is. How, when and by whom heritage can be contested and how it is related to or understood in relation to uncontested heritage are also unresolved questions. The contribution of this anthology thus falls at an intersection between the process-perspectives of critical heritage studies of cultural heritage, the empirical-historical studies of power and agency in social and cultural history (after the archival turn), and the conceptual fields that examine the use of history and history mediation. It rests firmly on the collective expertise drawn from historians and other scholars, at different stages of their careers, from researchers with theoretical proficiency as well as practical experience from cultural heritage work, both within and outside of traditional cultural heritage institutions. The result, if not a comprehensive rendering, is a range of multifaceted insights into research on why and how cultural heritage can be both contested and (un)contested.
