Mathias Fuelling is an historian of economic planning, socialism, and the nation-state in modern Europe. He received his PhD in History from Temple University in the autumn of 2025. His dissertation, The Forgotten Plan: The Czechoslovak Two Year Plan in a European Context, 1939-1989, studied the history of economic planning in Czechoslovakia, primarily the Two Year Plan of 1946-1948, connecting it with the legacy of the Nazi occupation of Bohemia and Moravia, and tracing its influence on domestic Czechoslovak politics across the Cold War. He is currently working on turning his dissertation into a book. He is also in the early stages of a second book project, which will study the intertwined legacies of Communist conceptions and policies regarding the nation-state, and of far-right and fascist proposals for European unification, on post-Cold War European politics.
