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.

Cleveland's unemployment rate increased dramatically during the Panic of 1893. Finally, riots broke out among the unemployed who condemned city leaders for their ineffective relief measures. According to the New York Times, "[t]he desire to stop work seemed to take possession of every laborer..." on May Day of 1894.
