Ada Kuskowski is a medieval historian and a legal historian. Her interdisciplinary work weaves together approaches from history, law and literature with the larger goal of understanding how legal cultures developed in Europe during the Middle Ages (ca. 500-1500). Her writing has focused on sources that might be described as “black letter law” and are often prone to positivist approaches. However, she interprets these materials as legal narratives that are imbedded in larger cultural contexts and examine them through the values, representations, expectations and mentalités that produced them and gave them meaning. She thus uses these sources to think about the stories that medieval actors told themselves about law, the language they used to express the norms by which their societies should function, and more broadly how ideas about right and order developed into ideas about law.

She is currently working on a book titled Law in the Vernacular: Composing Customary Law in Medieval France, which examines lay juristic communities in Northern France as they sought to theorize an oral and performed custom and express it in writing, and in vernacular language. It tells the story of the development of the law book, of custom as it shifts from practice to theorized norm, of the constitution of lay communities brought together by their interest in legal knowledge, of the constitution of authority within those communities, and more generally of the creative process that was fundamental to the customary legal culture of the day. Her next book project, titled Law of Conquest: A Medieval Prehistory of Colonial Lawwill provide a larger history of medieval legal approaches to conquest and colonization and the ways in which those set the stage for later colonial legal thought.

Kuskowski completed her Ph.D. at Cornell University in 2013, where she specialized in medieval legal history. She also holds Bachelor of Common Law and Bachelor of Civil Law degrees from McGill University Faculty of Law, and a Bachelor of Arts from McGill University. Prior to her arrival at Penn, she held the Jeremy duQuesnay Adams Centennial Professorship in Western European Medieval History as assistant professor at Southern Methodist University. She was also the Law & Society Postdoctoral Fellow at University of Wisconsin Madison Law School (2012-3), a Samuel I. Golieb Fellow in legal history at New York University Law School (2011-12), and a visiting scholar in the Quebec Research Centre for Private and Comparative Law at the McGill University Faculty of Law (2010).
