A pathbreaking new genealogy of statelessness Just as the modern state and the citizenship associated with it are commonly thought of as a European invention, so too is citizenship’s negation in the form of twentieth-century diaspora and statelessness. Statelessness sets forth a new genealogy, suggesting that Europe first encountered mass statelessness neither inside its own borders nor during the twentieth century, as Hannah Arendt so influentially claimed, but outside of itself—in the New World, several hundred years earlier. Through close readings of political philosophers from Hobbes to Rousseau to Kant, Tony C. Brown argues that statelessness became a central problem for political thought early on, with far-reaching implications for thinking both on the state and on being human. What Europeans thought they saw among the “savages” of the Americas was life without political order, life less than human. Lacking almost everything those deemed clearly human had achieved, the stateless existed in a radically precarious, almost inhuman privation. And yet this existence also raised the unsettling possibility that state-based existence may not be inevitable, necessary, or even ideal.  This possibility, as Brown shows, prompts the response—as defensive as it was aggressive—that we call Enlightenment political philosophy, which arguably still orders much thinking on being stateless today, including our discourses concerning migrants and Indigenous peoples.
