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.
Jujuy Province
During the May Revolution and the battles for the independence of the "United provinces of the South", many confrontations took place in Jujuy because the Spanish concentrated their forces in Peru. The people of Jujuy had to endure the Jujuy Exodus, a massive evacuation with a scorched earth policy, led by General Manuel Belgrano. Finally the Spanish surrendered, but the war seriously affected the economy of the area.
