Though the organising institutions and the venues where historically loaded sites of anthropological legacy, the event attracted researchers, practitioners and activists from a wide range of backgrounds and disciplinary traditions: visual and performing artists, designers, museologists, curators, art historians, architects, urbanists, as well as anthropologists and those locating themselves in transitioning, often undefined domains.It was in this eclectic milieu that, together with the contributors to this issue, we discussed, among other things, the implications of making art with and for communities, and what this entails in terms of practice, ethics, participation and identity politics. Artists have engaged with communities since ancient times in both consensual and conflicting ways. Indeed, art has represented, moulded and reinvented communities through artworks that still puzzle contemporary observers (see Wong on this issue). Conversely, artistic works have been "socialised" in different epochs depending on the specific social, cultural and historical context in which they were situated. That is, forms and strategies of community engagement also depended on what Rànciere defines the "regime of the arts" in which artistic works were produced
