Historiography of the May Revolution
The last years of the 19th century and the beginning of the 20th were marked in Argentina by a growing industrialization process and the arrival of huge numbers of European immigrants. Historiographical studies were increased by the ""New Historical school"", in order to forge a "national identity", and the May Revolution had great prominence. There were discussions about the level of influence that the many causes of the May Revolution actually had, or whose interventions were the most decisive, but two points shared by all historians were to consider the May Revolution as the birth of Argentina, and to consider it an inevitable consequence of the causes that led to it (meaning, the chance of the May Revolution never taking place is not considered a feasible possibility by historians). There was also a subtle change: the scope of the revolution as a subject of study originally "started" with the events of May 1810 in Buenos Aires and kept going on for decades. They were later split, and the name "May Revolution" made reference only to events that led to the removal of Cisneros and the creation of the Primera Junta. A new element added by those historians was to consider, either to support or reject the idea, whenever there was an active and strong popular support for the Revolution, instead of explaining it solely around the actions of a limited number of enlightened men. Nevertheless, they kept the previous approaches for the most part.
Historiography of the May Revolution
Meanwhile, Esteban Echeverría epitomized the ideals of May in the concepts of progress and democracy. In the future, these concepts would be the axis around which revisionist history would differ from the canonical history in reference to the events of May. The canonical version claimed progress and justify the abandonment or delay the realization of democratic ideals in order not to risk the economic prosperity of society arguing that even then was not able to properly take advantage of political freedom. This situation was known as the establishment of the "Possible Republic." Mitre and Echeverría were part of the '37 Generation, a group of romantic authors born during the revolution itself and formed in the local context generated after it. Those authors did not work purely in intellectual fields, but took instead active part in the political events of their time, and strongly opposed the governor Juan Manuel de Rosas. They were closer to the unitarians than to the federalists, but were not fully unitarians either: they thought that it wasn't enough to apply directly the new ideas generated in Europe or the United States, but instead to adapt them to the local contexts of the Río de la Plata. They choose the May Revolution as the point to mark the birth of the nation because of their rejection to the Spanish or aboriginal cultures.
