Luis Tercero Casado is an independent scholar who earned his PhD in Modern History from the University of Vienna (2017) with a dissertation on the political relations between the two main branches of the Habsburgs after the Peace of Westphalia (1648-1659). Although this diplomatic scenario has been the main object of his research, other fields of interest are the history of the House of Austria during the seventeenth century, early modern diplomatic history and Spanish political and cultural interaction at the Imperial Court of Vienna. He has published various essays and book chapters on these and other related topics.
