Rein Taagepera, Ph.D. in physics, received in 2008 the Johan Skytte Prize, the largest in political science worldwide. His books include Predicting Party Sizes (2007), Making Social Sciences More Scientific (2008), and (with Matthew Shugart) Votes from Seats: Logical Models of Electoral Systems (2017). Miroslav Nemčok is a Postdoctoral Fellow at the Department of Political Science, University of Oslo. His research addresses a variety of topics – ranging from comparative political institutions and party politics to the people's experiences with political systems – which all tackle the question: why people support democratic systems?
'Rein Taagepera and Miroslav Nemčok present, document, and discuss an extremely important historical trend: the enlarging size of political communities. In addition, they cautiously present intriguing extrapolations for future developments. The topic is fascinating, and the authors' treatment is superior to everything written before. This should become a reference book with long-term validity.' Josep M. Colomer, Georgetown University 'Taagepera and Nemčok have produced a masterful synthesis of history, anthropology, political science, geography, and applied mathematics that spans the globe and millennia of human existence to generalize about how population size and the number (and nature) of polities are systematically related. The book is chock-full of findings that will enlighten and often surprise, along with important cautions about what the uncovered trends may portend for humanity's future.' Matthew S. Shugart, Distinguished Professor Emeritus, University of California, Davis 'This book summarizes and extends Rein Taagepera's earlier prodigious quantitative comparative studies of the territorial sizes of empires and puts his results in a larger anthropological comparative framework that also considers primate groups, tribes, and chiefdoms. The methodological approach combines careful estimations of quantitative measures that make it possible to compare the scales and temporal changes in scale across cultures and civilizations over a very long period up to the present. This volume also adds the study of populations of polities and the sizes of cities which provides new insights into the timing and location of the upsweeps and down-sweeps of scale. This produces original insights about the nature of sociocultural evolution that have important implications for the future.' Christopher Chase-Dunn, University of California, Riverside
