The Nordic popular education tradition, with folk high schools and study associations, is often pointed out as a regional characteristic with great significance for the development of democracy in this part of the world. Research on popular education has a long history in the Nordic countries. However, it has been characterized by a national focus, despite similar popular education activities occurring in neighboring countries. This project aims to create a long-term sustainable infrastructure for Nordic research collaboration to promote and develop research on popular education in the Nordic countries, especially comparative studies.
