Until recently many political scientists tended to regard violent civil conflict as a disfigurement of the body politic, neither a significant nor a proper topic for their empirical inquiries. The attitude was in part our legacy from Thomas Hobbes's contention that violence is the negation of political order, a subject fit less for study than for admonition. Moreover, neither the legalistic nor the institutional approaches that dominated traditional political science could provide much insight into group action that was regarded by definition as illegal and the antithesis of institutionalized political life.
