This is a social and political history of the Argentine landowners, for many decades Latin America's most affluent propertied class. Roy Hora develops a historically based view of how socio-economic and political change affected the landowners and was in turn affected by them between the1860s and 1940s. He questions the excessively static picture of the landowners of the pampas, which unquestioningly accepts the image of power, lineage, and permanence given by both panegyrists and critics of the estancieros. Dr Hora challenges the view of a powerful, reactionary landed class,dominating the country's history from colonial times to the rise of Peronism in the 1940s. But he also challenges revisionist interpretations which seek to de-emphasize the central role played by the landowning class in the evolution of modern Argentina.
