Historiography of the May Revolution
Historiographical studies of the May Revolution started in the second half of the 19th century in Argentina and have extended to modern day. All historiographical perspectives agree in considering the May Revolution as the turning point that gave birth to the modern nation of Argentina, and that the Revolution was unavoidable in 1810. The main topics of disagreement between Argentine historians are the specific weight of the diverse causes of the May Revolution, who were the leaders of it among the different involved parties, whenever there was popular support for it or not, and whenever the loyalty to the captive Spanish king Ferdinand VII was real or an elaborate masquerade to conceal pro-independence purposes.
Latin American wars of independence
Following the events of the May Revolution, in 1811 José Gervasio Artigas, led a successful revolt against the Spanish forces in the Provincia Oriental, now Uruguay, joining the independentist movement that was taking place in the Viceroyalty of the Río de la Plata at the time. In 1821, the Provincia Oriental was invaded by Portugal, trying to annex it into Brazil under the name of Província Cisplatina.
