Jauretche combined his own interpretation of contemporary reality with the nascent techniques of historical revisionism. Although revisionist authors had been advocating a reinterpretation of Argentine history — in opposition to the canonical vision of Bartolomé Mitre and Sarmiento which had represented the nation's development in terms of a clash between civilization and barbarism — since at least the 1930s, it was not until the "Revolución Libertadora" that major parallels began to be drawn between Perón and Juan Manuel de Rosas. When Aramburu's supporters declared the coup against Perón "a new Caseros", the revisionists rose to the challenge, portraying Caseros as the beginning of a historical disaster that the government of Rosas had kept at bay through a policy that united the interests of disparate social classes.
