In The Frontier Effect, Teo Ballvé challenges the notion that in Urabá, Colombia, the cause of the region's violent history and unruly contemporary condition is the absence of the state. Although he takes this locally oft-repeated claim seriously, he demonstrates in The Frontier Effect that Urabá is more than a case of Hobbesian political disorder. An insightful exploration of violence, paramilitary organizations, grassroots support and resistance, and so-called "New Wars," The Frontier Effect argues that Urabá, rather than existing in statelessness, has actually been an intense and persistent sire of state-building projects. Indeed, these projects have thrust together an unlikely gathering of guerilla groups, drug-trafficking paramilitaries, military strategists, technocratic planners, local politicians, and development experts in an attempt to give concrete coherence to the inherently unwieldy abstraction of "the state" in a space in which it supposedly does not exist. By untangling this odd mix, Ballvé reveals how Colombia's violent conflicts have produced surprisingly coherent and resilient, if not at all benevolent, regimes of rule.
