This subject was chosen because generally accepted interpretations of territorial communities equate them with traditional organizations. Treatments of the legal organization of territorial community management are based thereon and do not consider the altered needs of social development. This book aims to create a theoretically ordered basis for territorial communities and the legal organization of their management. The research object is the established legal organization of the management of territorial communities. The research has produced a new basis for treating territorial communities and the legal organization of their management. Theoretical models and solutions that take into account the current needs for changes in the legal organization of the management of territorial communities are also presented. This should help to guarantee the level of public services and their availability, and thereby improve the quality of everyday life. The book is based on the case of Estonia, but is also relevant elsewhere. The target audience includes researchers, faculty members and students, as well as practitioners who are interested in the topic of territorial communities.
