The new country of Argentina lacked an established concept of national identity capable to unite the population under a common idea of statehood. Juan Bautista Alberdi sees the May Revolution as one of the early manifestations of the power struggles between the city of Buenos Aires and the provinces—one of the axial conflicts at play in the Argentine civil wars. Alberdi wrote in his book "Escritos póstumos": The revolution of May 1810 in Buenos Aires, intended to win the independence of Argentina from Spain, also had the consequence of emancipating the province of Buenos Aires from Argentina or, rather, of imposing the authority of this province upon the whole nation emancipated from Spain. That day, Spanish power over the Argentine provinces ended and that of Buenos Aires was established. Historical perspectives Historiographical studies of the May Revolution do not face many doubts or unknown details. Most of the information was properly recorded at the time and was made available to the public by the Primera Junta as patriotic propaganda. Because of this, historical views on the topic differ in their interpretations of the meanings, causes and consequences of the events, rather than in the accuracy of their depiction of the events themselves. The modern version of events does not differ significantly from the contemporary one. The first people to write about the May Revolution were participants who wrote memoirs, biographies and diaries. However, their works were motivated by purposes other than historiographic ones, such as to explain the reasons for their actions, clean their public images, or express their support or rejection of the public figures and ideas of the time. For example, Manuel Moreno wrote the biography of his brother Mariano as propaganda for the revolutions in Europe, and Cornelio Saavedra wrote his autobiography at a moment when his image was highly questioned, to justify himself to his sons. The first remarkable historiographical school of interpretation of the history of Argentina was founded by members of the 1837 generation, including Bartolomé Mitre. Mitre regarded the May Revolution as an iconic expression of political egalitarianism: a conflict between modern freedoms and oppression represented by the Spanish monarchy, and an attempt to establish a national organization on constitutional principles as opposed to the charismatic authority of the caudillos. These authors' views were treated as canonical until the end of the 19th century, when the proximity of the centennial encouraged authors to
