Migrations and immigration at the museum. The movement is international. This new exhibition topic covers new questions about the collective identity of contemporary societies. In the US, Canada, Australia or France, how do specific institutions address the history of immigration? How do they link it to the national fact? What inclusion discourse do they bring? What social imagination crosses them? Meeting migrants’ memories, museography becomes a means of recognition as a vehicle for visibility. Receptacle museum of an ethnic community. Virtual museum documenting the past of a city of immigrants online. Exhibition policy on the diversity of memories at regional level... All of these experiences have been put into perspective by French and foreign academics and curators. But these issues do not emerge without debate or dissertation. And what is happening on this occasion is worth talking about other confrontational inheritances. Hence, analyses of the limits of the heritage care of slavery in the Antilles, the indigenous perspective in the ‘settler societies’, or the memorial clashes about the French colonial past. Finally, it is outside the museum that we have to watch. It is also through cultural action in the broad sense that such challenges arise. From the work of grassroots associations to promote memories from “the other” or “Suds” to the general public, to projects under way at European level around migration heritage.
