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.
Dos de Mayo Uprising
On 2 May a crowd began to gather in front of the Royal Palace in Madrid. Those gathered entered the palace grounds in an attempt to prevent the removal of Francisco de Paula. Marshal Murat sent a battalion of grenadiers from the Imperial Guard to the palace along with artillery detachments. The latter opened fire on the assembled crowd, and the rebellion began to spread to other parts of the city.
