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
For Britain the change was favorable, as it facilitated trade with the cities of the area without seeing it hampered by the monopoly that Spain maintained over their colonies. However, Britain prioritized the war in Europe against France, allied with the Spanish power sector that had not yet been submitted, and could not appear to support American independentist movements or allow military attention of Spain being divided into two different fronts. Consequently, they pushed for independence demonstrations not being made explicit. This pressure was exerted by Lord Strangford, the British ambassador at the court of Rio de Janeiro, expressing support to the Junta, but conditioned ""...if the behavior is consistent and that Capital retained on behalf of Mr. Dn. Fernando VII and his legitimate successors."" However, the following conflicts between Buenos Aires, Montevideo and Artigas led to internal conflicts in the British front, between Strangford and the Portuguese regent John VI of Portugal.
