Tara Zahra is a professor of history at the University of Chicago. Her research focuses on the transnational history of modern Europe, migration, the family, nationalism, and humanitarianism. She is currently working on two book projects: a history of deglobalization in interwar Europe and, with Pieter Judson, a history of the First World War in the Habsburg Empire. Zahra is most recently the author of The Great Departure: Mass Migration and the Making of the Free World (Norton, 2016) and, with Leora Auslander, Objects of War: The Material Culture of Conflict and Displacement (Cornell, 2018). Her previous books include The Lost Children: Reconstructing Europe's Families after World War II (Harvard, 2011) and Kidnapped Souls: National Indifference and the Battle for Children in the Bohemian Lands (Cornell, 2008).
