Pieter M. Judson (born 1956, Utrecht) is an American historian specializing in the history of Central Europe, the Habsburg monarchy, and modern nationalism. He has held academic appointments in the United States and Europe, including a Chair in 19th and 20th Century History at the European University Institute (EUI) in Florence.
Judson earned his Bachelor of Arts from Swarthmore College in 1978. He continued his studies at Columbia University, where he received his Master of Arts in 1981 and his PhD in 1987 under the supervision of István Deák.
Judson began his academic career as Assistant Professor of History at Pitzer College, where he taught from 1988 to 1992. In 1993 he joined Swarthmore College as Assistant Professor of History. He was promoted to Associate Professor with tenure in 1996 and to Full Professor in 2004. During his tenure at Swarthmore, he served as Head of the History Department from 2001 to 2006 and held the Isaac H. Clothier Professorship of History and International Relations from 2011 to 2013.
Starting in 1994, Judson introduced a course on Sexuality and Gender in Modern Europe as part of the History curriculum.
In 2014, Judson was appointed Chair in 19th and 20th Century History at the European University Institute in Florence. He served as Head of the Department of History and Civilization from 2015 to 2018. After completing his term as chair, he continued at the Institute as Part-time Professor of History (2024âÂÂ2025) and Senior Fellow in the Department of History (2025âÂÂ2026).
JudsonâÂÂs research focuses on the political, social, and cultural history of Central Europe in the nineteenth and early twentieth centuries, with particular emphasis on the Habsburg monarchy, nationalism, liberalism, imperial governance, and borderlands. His work examines how national identities were constructed, negotiated, and contested within imperial institutions and everyday social practices.
A central theme of his scholarship is the reinterpretation of the Habsburg Empire as a functioning and adaptive imperial polity rather than a failed âÂÂprison of peoples.â In collaboration with former students and co-authors, Judson contributed to the development of the concept of âÂÂnational indifference,â a framework used by historians to analyze populations whose political loyalties and cultural practices did not conform to rigid national categories. His publications on the Habsburg Empire and Central Europe have appeared in numerous languages, and his book The Habsburg Empire: A New History has been translated into multiple European and Asian languages. Judson has served as editor of the Austrian History Yearbook (2006âÂÂ2011; 2011âÂÂ2016).
