The present volume opens with a chapter on folk religion as a field of cultural research in Scandinavia. A major portion of my research has been concerned with conditions in the coastal province of Bohuslän in western Sweden, with glimpses of neighbouring areas in Norway. In Bohuslän free churches and intra-church revival movements have played an important role since the late 1800s. I have therefore studied different aspects of such movements in some of the chapters. Religious contacts over the national border between Norway and Sweden have also been a subject of research. The most intensive study has focused on the many different aspects of the Pentecostal Movement on the island of Åstol in Bohuslän.
