Blending the tools of micro-history with historical Geographical Information Systems (GIS) permits us to chart the social networks and everyday journeys of black working-class women activists and the middle-class men with whom they came into contact in Reconstruction St. Louis. Social and spatial ties shaped the activism of St. Louis’ working-class women; mapping these ties reveals the links between everyday acts of resistance and organized efforts of African Americans to carve out a space for themselves in the restructuring city and make visible a collective activism that crossed class and racial boundaries.
