As the field of family business has grown immensely over the last couple of decades, a multitude of theories from different fields has been introduced. However, there are surprisingly few attempts to provide an overview of theories that may be of particular interest for the family business scholar. Thus, this introduction chapter gives a critical overview of theoretical perspectives, before taking a closer look at the use of theories in family business studies. Regarding the current state of the family business field, the authors argue for putting more effort in building theory from family business research as well as a stronger emphasis on ‘giving back’ to theories borrowed from other fields. Lastly, the chapter describes the development of the book and introduces the 13 chapters and their contributions.
