On May 25, 1810, the Primera Junta was established in Buenos Aires, with Cornelio Saavedra at the head. Historians agree that the Revolution was not limited to a single date.

Some scholars say that the revolutionary process in the Viceroyalty of the Río de la Plata began around 1809, with the formation of the Junta del Alto Perú. The very mechanics of the events brought unexpected conflicts. The revolutionary leaders of 1810 tried to make all the territories that make up the Vicingoyalty obey them.
