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.
May Revolution
The May Revolution began the Argentine War of Independence, although no formal declaration of independence was issued at the time and the Primera Junta continued to govern in the name of the deposed king, Ferdinand VII. As similar events occurred in many other cities of the continent, the May Revolution is also considered one of the early events of the Spanish American wars of independence. Historians today debate whether the revolutionaries were truly loyal to the Spanish crown or whether the declaration of fidelity to the king was a necessary ruse to conceal the true objective—to achieve independence—from a population that was not yet ready to accept such a radical change. A formal declaration of independence was finally issued at the Congress of Tucumán on July 9, 1816.
