Adam Przywara presents a paper titled "Second Materiality of Warsaw: Ruins, Rubble and the Postwar Socialist Reconstruction” in the panel “Elements for the Future: Materials and Practices of Post-WW2 Reconstructions” on the annual conference of the largest association dedicated to scholars of Slavic, East European, and Eurasian Studies. The panel, chaired by Eve Blau, explores the connective practices and material networks that supported postwar rebuilding in socialist Poland and the Soviet Union. The papers by Sofia Dyak, Adam Przywara and Katherine Zubovich examine diverse cases of postwar reconstruction: efforts in Kyiv to compare, classify, and map Ukrainian cities in preparation for rebuilding; the transformation of Warsaw’s ruins into a material base of reconstruction through practices of salvaging, reusing and recycling rubble; and the material networks forged in the wake of war to link Soviet cities like Moscow to extractive spaces in newly “liberated” landscapes in the western USSR. Together, the papers represent a call to think more socially and relationally about the cities, landscapes, and materials we study.
