Baltasar Hidalgo de Cisneros
The news of the fall of the Junta of Seville reached Buenos Aires in May 1810. With both the king of Spain and the Junta removed of power, many people thought that Cisneros had no legitimacy to govern, starting the May Revolution. Cisneros tried to calm down the population, to no avail. He called the commanders of the local armies and requested their support, but they denied it. Cisneros was ultimately forced to allow an open cabildo, which would discuss what to do. Although those meetings were usually composed of the wealthiest population, the army and a group of rioters plotted to prevent the entry of many wealthy people and allow common people instead.
May Revolution
According to historian Félix Luna's "Breve historia de los Argentinos" (), one of the most important societal consequences of the May Revolution was the shift in the way the people and its rulers related. Until then, the conception of the common good prevailed: while royal authority was fully respected, if an instruction from the crown of Spain was considered detrimental to the common good of the local population, it was half-met or simply ignored. With the revolution, the concept of common good gave way to that of popular sovereignty, as theorized by Moreno, Castelli and Monteagudo, among others. This idea held that, in the absence of a legitimate authority, the people had the right to appoint their own leaders. Over time, popular sovereignty would give way to the idea of majority rule. This maturation of ideas was gradual, taking many decades to crystallize into stable electoral and political systems, but it was what ultimately led to the adoption of the republican system as the form of government for Argentina. Domingo Faustino Sarmiento stated similar views in his "Facundo", and noted that cities were more receptive to republican ideas, while rural areas were more resistant to them, which led to the surge of caudillos.
