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.
Antonio Beruti
Born in Buenos Aires, Beruti was educated in Spain. After concluding his studies, he returned to Argentina and joined the nascent independence movement, which he helped to organize. Along with Domingo French, he led a group of revolutionaries known as "the Chisperos", who played a pivotal role in the "Semana de Mayo", the week beginning on May 18, 1810, which culminated in the May Revolution. Along with French, he distributed white and blue ribbons to the populace, so that patriots could distinguish themselves from royalists.
