Ilie Bădescu and Joseph Livni follow the footsteps of two giants who pioneered the field: H. H. Stahl of Romania, who studied the sociology of communal societies, and D. J. Elazar of the United States, who studied the political science of covenantal societies. This collection sheds light on obscure corners of the field, gathering up thoughts and concepts of many other sources of past and contemporary research in the field. In this volume, the reader will find answers to difficult questions like: How did acephalous societies penetrate civilization? How did they manage to preserve their egalitarian ethos? Why did powerful hierarchies work in partnership with them? And, most importantly, how did covenantal societies work around the constraints of a civilized reality? The history of civilization consists of various degrees of stratified configurations ranging from oligarchic city states to powerful pyramidal empires.
