The Make America Great Again movement in the United States gives voice to a rising nationalism and tribalism we see around the world, from Modi\'s India, to Putin\'s Russian, Orban\'s Hungary, and Netanyahu\'s Israel. Against such a tribalism is the dream of a world citizenship, the cosmopolitan ideal that sees all human beings as part of one large political world. Tribalism and Cosmopolitanism is dedicated to exploring the humanity of both tribal affiliation and cosmopolitan dreams.

Volume 13 of the HA. The Yearbook of Hannah Arendt Center for Politics and Humanities centers on the compelling theme of tribalism and cosmopolitanism. Inspired by the 2024 Hannah Arendt Center Conference Tribalism and Cosmopolitanism: How Can We Imagine a Pluralist Politics, it brings together contributions by prominent thinkers such as Sebastian Junger, Fintan O\'Toole, Seyla Benhabib, Niobe Way, Leon Botstein, Lyndsey Stonebridge, and more, featuring insightful conversations and talks held at the conference, alongside in-depth essays that build on and expand on the themes of tribalism and cosmopolitanism. An illuminating anthology of texts relating to both tribalism and cosmopolitanism from Anthony Appiah, Hannah Arendt, Aristotle, Thomas Aquinas, Cicero, Emile Durkheim, Epictetus, Sigmund Freud, Immanuel Kant, Ibn Khaldûn, Martha Nussbaum, and more enriches the volume. The goal is to offer a broad introduction to the inquiry into the human tension between our need to belong to tribes and our aspirations to cosmopolitan humanism. Present scholarship and canonical texts are put into conversation to provide an extended sourcebook of ideas for the interested reader.
