This research project brings together an international group of researchers to share their research on the economic activities and agency of queens and royal women across premodern Europe. Through a series of events, including online workshops and hybrid conferences, we bring together case studies from our project participants which demonstrate the role of queens and royal women as administrators of large portfolios of landholdings, investors in cultural and business enterprises and financial managers of diverse streams of revenue and complex household budgets. Through the presentations of individual research and group discussions, we are building a better understanding of key themes and issues in the economic aspect of rulership with regards to a variety of royal women including the consorts of sovereign and territorial rulers, regnant queens and dowagers. We examine trends of continuity and change over time and compare different frameworks for queenly finances. Ultimately, we aim in a future phase of the project to bring this work together into a database to map the lands, revenues and resources controlled by royal women and provide links to key documents to promote further study which will increase our understanding of the important, yet understudied, aspect of rulership.
