May Revolution
The May Revolution was not the product of the actions of a single political party with a clear and defined agenda, but a convergence of sectors with varying interests. Thus, there are a number of conflicting perspectives about it, because different authors highlight different aspects. Mitre, for example, referred to "The Representation of the Landowners" (an 1809 economic report by Mariano Moreno) and the role of the merchants to support the view that the May Revolution intended to obtain free trade and economic integration with Europe; right-wing revisionists center around Saavedra and the social customs of the time to describe the revolution under conservative principles; and left-wing revisionists use the example of Moreno, Castelli and the rioters led by French and Beruti to describe it as a radical revolution.
Mutiny of Álzaga
Historian Bartolomé Mitre explained the mutiny of Álzaga and the May Revolution as closely related events, with the former being an antecedent of the later. This approach was rejected by Vicente Fidel López, who described Álzaga as highly pro-Spanish, decided monarchist and keeper of the Spanish integrity against the goals of the Criollos. He interpreted the events as mere domestic policy, a dispute about who was more loyal to the king, and deemed Álzaga as counter-revolutionary for acting against the goals of the factions that would eventually prevail in the May Revolution a year later. Later historians would accept López's version as canonical.
