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
The May Revolution began the Argentine War of Independence, although no formal declaration of independence was issued at the time and the Primera Junta continued to govern in the name of the deposed king, Ferdinand VII. As similar events occurred in many other cities of the continent, the May Revolution is also considered one of the early events of the Spanish American wars of independence. Historians today debate whether the revolutionaries were truly loyal to the Spanish crown or whether the declaration of fidelity to the king was a necessary ruse to conceal the true objective—to achieve independence—from a population that was not yet ready to accept such a radical change. A formal declaration of independence was finally issued at the Congress of Tucumán on July 9, 1816.
