This edited collection, which brings together nearly fifty authors from across the globe and various disciplines, makes a valuable contribution to the field of conservation, covering a wide range of topics regarding the protection of heritage in times of war and peace. Uniquely linking the two typically separate perspectives, the book builds on the wealth of discussions that took place during the 2021 and 2022 installments of the international “Heritage in War and Peace” Seminars held in Rome and Montréal, respectively. Issues explored in the volume include but are not limited to questions surrounding the protection of contentious heritages, unsustainability of the current dichotomic cultural/natural heritage protection frameworks, digitalization of heritage, place of heritage in military conflicts, use of heritage by armed non-state actors, indigenous peoples’ relationships with heritage, the intersection of intellectual property (IP) law and heritage, human rights matters linked to heritage protection, and the latest case studies surrounding restitution. Given its scope, the book will be of particular interest not only to practitioners and conservation specialists but also to academics and students in the broader social sciences and humanities, and to all those who hope to preserve our heritage for future generations.
