In this article that we wrote with Ieva Astahovska for the Museum of Modern Art (MoMA) Post platform we review the ongoing research and exchange project “Communicating Difficult Pasts” (2019-24), its different activities, its creative and curatorial methods used. In the project we approach Baltic history as global and closely entangled with its adjacent regions. In this article we propose to see the project as a process of reworking cultural traumas by using art in a way that integrates art’s potential to create new solidarities.
