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.

The "Día de la Revolución de Mayo" (May Revolution Day) on May 25 is an annual holiday in Argentina to commemorate the First National Government (and the creation of the Primera Junta), one of the significant events in the history of Argentina. These and other events of the week leading to this day are referred to as the "Semana de Mayo" (May Week).
