This second edition of Historical Dictionary of "The Dirty Wars" focuses on the period 1954-1990 in South America, when authoritarian regimes waged war on subversion, both real and imagined. This is done through a chronology, an introductory essay, a bibliography, and over 400 cross-referenced dictionary entries on the countries; guerrilla and political movements; prominent guerrilla, human-rights, military, and political figures; local, regional, and international human-rights organizations; and artistic figures (filmmakers, novelists, and playwrights) whose works attempt to represent or resist the period of repression.
