How might the end of white supremacy transform American cities? Journalists and scholars have exposed their misbegotten foundations: slave labor and subprime mortgages, redlining and white flight, neighborhoods leveled by lynch mobs, renewal schemes, “natural” disasters, and interstate highways. Visions of an emancipated landscape, on the other hand, are fewer, and often left to be improvised by artists or mass movements. Last summer’s uprisings, which began with the torching of a police station in Minneapolis and survived through the creative occupation of streets, bridges, and civic centers across the country, gave many protesters a new ideal of solidarity and free urban space. Another city is possible. But who will draw up the plans?
