This series was launched in 2021 by the Working Group of Economic and Social History of the Pécs Regional Committee of the Hungarian Academy of Sciences to present research conducted within its framework. The foreign language edition is meant to be a contribution to the internationalization of research made in Hungary. The Working Group has made every effort since the publication of the first two volumes to allow its members, and also their Ph.D. students, to publish their findings more easily and in larger volume, providing at the same time an opportunity for other professionals in the region of South Transdanubia to publish their researches. The majority of the studies in this book, similarly to the first volume of the series, are about the history of the region, but some of the papers go beyond this theme. The diversity of the papers created an inspiring environment for the authors, which in turn has greatly stimulated the already existing professional cooperation among them. Both the editors and the authors find it very important to popularise the economic and social history of the region as broadly as possible, in line with the ambitions of the Pécs Regional Committee of the Hungarian Academy of Sciences. In addition, this book also promotes the cooperation among generations of researchers; it is not only the young that enjoy the support of their senior colleagues but the ideas and momentum of the younger generation also keep the activity of the Working Group at a high level. It is due to the well-functioning generational discussions, among other things, that several young researchers earned their Ph.D. degree in 2021. The framework of the studies in the broader sense is the economic and social history of Hungary and Europe in the 18th – 20th centuries. The papers in this volume also provide information about the development and current phases of the different pieces of research. Several papers are sequels to publications released in 2021 from a chronological or thematic aspect, however the book contains brand new topics as well. Great significance is attributed to the fact that several renowned international members of the research network of the Working Group were also persuaded to publish. The results of some ongoing Ph.D. research are also presented. The high number of young authors is a proof that the professional interest in economic and social history is not decreasing at all. We do hope that this book will contribute to the maintenance of this trend.
