Casa do Povo and Diaspora Alliance presented Memories in Dispute: Struggles in the Diaspora, Alliances and Complicities, an international seminar that seeks to rethink the uses of memory, challenge the politics of fear, and highlight forms of struggle against racism, antisemitism, and ethnonationalism. In times of pain and uncertainty, transnational articulations and solidarities for the development of collective strategies become essential. We see how recent traumas have been instrumentalized to justify violent actions, and how new forms of nationalism have emerged, grounded in imagined identity constructions. In contrast, it is crucial to reclaim our memories, in all their diversity, to challenge fear-based politics and to design and sustain other alliances across diasporas.
