The institution of the family changed hugely during the course of the twentieth century. In this major new work, Göran Therborn provides a global history and sociology of the family as an institution and of politics within the family, focusing on three dimensions of family relations: on the rights and powers of fathers and husbands; on marriage, cohabitation and extra-marital sexuality; and on population policy. Therborn's empirical analysis uses a multi-disciplinary approach to show how the major family systems of the world have been formed and developed. Therborn concludes by assessing what changes the family might see during the next century. This book will be essential reading for anybody with an interest in either the sociology or the history of the family.
