The rebuilding of bombed-out cities in Western Europe after the end of World War II has predominantly been narrated as an unprecedented instance of modernist town planning and architecture. Historiography tends to present fine-grained analyses of the plans and planners involved in the resurrection of some of Europe's most important port and industrial cities during the post war decades. Only fairly recently scholars have also engaged with the collective and individual experiences of urbanites, for instance by articulating (transnational) cultures of commemoration of war or by pursuing ethnographic research in post war neighbourhoods. Yet, what seems to be lacking at large, still, is historical inquiry into the ramifications of modernist planning for post war city life. As becomes clear from the sources, urban and planning authorities had clear ideas about who belonged to the post war urban community - and who did not. Reconstruction politics prompted processes of expulsion, stigmatization and social exclusion for citizens who did not fit the post war social template. To them modernist reconstruction amounted to 'a second trauma' after the war. This talk will present examples from cities such as Rotterdam, Marseille, Coventry and Hamburg and will try to conceptualize these post war practices of social exclusion. As usual, we convene in OIH/BH E1.02 from 15:00 to 16:30, followed by drinks. All are welcome.
