Covadonga Valdaliso Casanova is a researcher and Deputy Director at the Centro de História da Faculdade de Letras of the University of Lisbon (CH-ULisboa), and a collaborator at the CHSC (U. Coimbra) and the CEC (U. Lisboa). Having completed her doctoral studies in Medieval History at the University of Valladolid (2007), after obtaining a Bachelor's degree in History from the University of Cantabria (2000), for eight years she worked as a postdoctoral fellow, first at the University of Lisbon and later at the University of Coimbra. Her expertise lies in the field of Iberian history during the late Middle Ages, with a particular focus on topics related to the exercise of monarchical power, its legitimization, and the construction and preservation of memory during that period. She has specialized in exploring the intricate dynamics of political authority and the ways in which monarchs sought to establish and maintain the legitimacy of the territories they controlled. In recent years, she has successfully completed a doctoral degree in Medieval Literature at the University of Alcalá (2023), further expanding her interdisciplinary approach to historical research. These doctoral studies have primarily focused on the study of medieval brief historiography and the uses of the past in the Middle Ages. By examining the ways in which medieval authors constructed and interpreted historical events, she seeks to shed light on the relationship between memory, narrative, and the shaping of collective identities.
