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 ideals of the French Revolution of 1789 spread across Europe and the Americas as well. The overthrow and execution of King Louis XVI and Queen Marie Antoinette ended centuries of monarchy and removed the privileges of the nobility. Liberal ideals in the political and economic fields developed and spread through the Atlantic Revolutions across most of the Western world. The concept of the divine right of kings was questioned by the French "Declaration of the Rights of Man and of the Citizen", by the oft-quoted statement that "all men are created equal" in the United States Declaration of Independence and even by the Spanish church.
