In Uncivil Guard: Policing, Military Culture, and the Coming of the Spanish Civil War, Foster Chamberlin evaluates the role of militarized police forces in the political violence of interwar Europe by tracing the evolution of one such group, Spain's Civil Guard, culminating in the country's turbulent Second Republic period of 1931-1936. As Chamberlin's analysis shows, political violence provided the main justification for the military coup attempt that began the Spanish Civil War, and the Civil Guard was the most violent institution in the country at that time. Discovering how this police force, which was supposed to maintain order, became a principal contributor to the violence of the republic proves key to understanding the origins of the Civil War. By tracing the institution's founding in the mid-nineteenth century, and moving through case studies of episodes of political violence involving the group, Chamberlin concludes that the Civil Guard had an organizational culture that made it prone to violent actions because of its cult of honor, its distance from the people it policed, and its almost entirely military training.
