A Nation Forged by Empire: The Hidden Legacy of German Colonialism
During his fellowship at global dis:connect, Matthias will complete his current book project on the legacy of German colonialism. Drawing on a wide range of sources from European and African archives, the study shows how and why the German overseas empire helped consolidate the nascent German nation-state. Germany soon lost its colonies, but their effects on the country persisted, leaving a complex legacy.

Yvonne is a professor of Eastern European history and director of the Aleksander Brückner Center for Polish Studies at Halle University. Her research focuses on Russian imperial history in comparative perspective, Jewish history of Eastern Europe, and Polish history through the ages.

Judd is a professor of modern Chinese history at the University of Wisconsin-Madison. His research treats borderlands, materiality and natural resources. He is currently working on the transnational exchange of Chinese raw materials for cash, weapons and industrial goods during World War II. This work reveals the transnational networks that developed to finance, produce and transport such resources. These trans-Pacific networks channelled objects in both directions during the war and served as the blueprint of a new postwar international order.
Judd works in both Chinese and English, with experience researching in several archives in China, Taiwan, the United States and the United Kingdom.
