This introduction argues that the field of memory studies needs to pay more attention to the role of joyful and positive types of memory. Quoting recent discussions, we propose that the dominant focus on traumatic and dark pasts within memory studies carries the risks that the research field ignores important aspects of collective memory and eclipses group memories that differ from societies’ hegemonic discourse about the past. Contemporary societies also need positive or hopeful memories in order to create alternative imaginaries for the future. This special issue sets out to explore what memories of joy may look like and how they can be studied.
