One of the most vexing questions posed over time by political scientists is: Why do democratic polities develop in some countries, but not in others? In his seminal work Social Origins of Dictatorship and Democracy (1986), still read today by most students of comparative politics, Barrington Moore strove to answer that question by examining the historical process in which commercial agriculture emerged in Britain, France, Germany, Russia, and China. In his book, Fernando López-Alves takes the framework that Moore provided and applies it to three countries in Latin America whose trajectories in the nineteenth century led to different polities and experiences with democracy—Argentina, Colombia, and Uruguay (he also makes brief reference to Paraguay and Venezuela as so-called control cases). While conceding the need for “further testing” (p. 220), he arrives at conclusions that differ significantly from Moore's, even though he does not attempt to dismiss that earlier work.
