In the early hours of 1994, a few hundred men and women of the Ejército Zapatista Liberación Nacional (EZLN) blocked the Pan American Highway between Tuxtla Gutiérrez, the state capital of Chiapas, and San Cristóbal de las Casas and the road to Ocosingo, declaring war on Mexico's ruling Partido Revolucionario Institucional (PRI). This move signaled to the world that indigenous populations intended to make themselves heard at home and abroad as Mexico restructures its economy according to the neoliberal model promoted by President Carlos Salinas de Gortari. The rebels captured and briefly held the municipal buildings in San Cristóbal, Altamirano, Las Margaritas, and Ocosingo. Speaking for the rebels, Subcomandante Marcos declared that their war was “a final but justified measure”: “We have nothing, absolutely nothing. Not a decent roof, nor work, nor land, nor health care, nor education.”

Inequality in the distribution of land has long been viewed as the social dynamite that has set off many peasant uprisings in the twentieth century. The most extensive study to date of modern guerrilla wars in Latin America, by Timothy Wickham-Crowley, found land tenure and the overall agrarian structure to be a common element in upheaval in Cuba, Venezuela, Guatemala, Colombia, Peru, Nicaragua, and El Salvador (Wickham-Crowley 1992, 306–7). Samuel Huntington's classic book on development and stability articulated the explanation for these agrarian insurrections: “Where the conditions of landownership are equitable and provide a viable living for the peasant, revolution is unlikely. Where they are inequitable and where the peasant lives in poverty and suffering, revolution is likely, if not inevitable, unless the government takes prompt measures to remedy these conditions” (Huntington 1968, 375).

In the last ten years, the rural history of the colonial Río de la Plata and to a lesser extent that of the first half of the nineteenth century have witnessed an unprecedented boom. Research projects, new sets of questions, and the utilization of new sources and methodologies have all proliferated. Today we have undoubtedly come a long way in our understanding of these issues from where we were only a decade ago.
