This book is a result of the conference “The History of Legal Aid in the Premodern and Modern World” which was held at the University of Turku, Finland, in March 2019. We would like to thank the Faculty of Law at the University of Turku, the Finnish Lawyers’ Association, as well as the research project “Legal Literacy in Finland ca. 1750–1920: A Case of Popular Legal Learning in Premodern Europe” (no. 309055), funded by the Academy of Finland, for financing the conference and supporting this book project. We also thank all the participants of the conference for their thought-provoking presentations and for the fruitful discussions that ensued. We are also grateful to Hazel Salminen, who helped us with the language revision of some of the chapters, and to Anita Geritz for her invaluable assistance in editing this book.
