The racial and cultural politics of land and property are central to urban struggle, but have received relatively little attention in geography. This paper analyzes land struggles in Detroit where over 100,000 parcels of land are classified as “vacant”. Since 2010, planners and government officials have been developing controversial plans to ruralize Detroit's “vacant” neighborhoods as part of a program of fiscal austerity, reigniting old questions of racialized dispossession, sovereignty, and struggles for liberation. This paper analyzes these contentious politics by examining disputes over a white businessman's proposal to build the world's largest urban forest in the center of a Black majority city. I focus on how residents, urban farmers, and community activists resisted the project by making counterclaims to vacant land as an urban commons. They argued that the land is inhabited not empty and that it belonged to those who labored upon and suffered for it. Combining community‐based ethnography with insights from critical property theory, critical race studies, and postcolonial theory, I argue that land struggles in Detroit are more than distributional conflicts over resources. They are inextricable from debates over notions of race, property, and citizenship that undergird modern liberal democracies and ongoing struggles for decolonization.
