Democracy, Charles Tilly, New York: Cambridge University Press, 2007, pp. xi, 227.

The ideal of democracy is rarely challenged openly in the contemporary world, yet it remains one of the social science's essentially contested concepts. Despite a large and growing literature on the topic, there is little consensus on how we are to decide when a particular regime qualifies as a democracy or not. In his ambitious and forceful new book, Charles Tilly argues that this lack of a clear and accurate definition of democracy is of considerable consequence. Lucid explanations of democratization, political standing of regimes, related foreign policy decisions and the quality of people's lives are all at stake. Tilly devotes his first chapter to building a working definition of democracy before putting forward a cogent explanatory framework for understanding how and why democracies emerge and why they sometimes disappear and to demonstrate what difference it makes.
