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 Fourth Square
The May 4th Movement (五四运动, wǔsì yùndòng) was sparked by Article 156 of the Treaty of Versailles which transferred German concessions in Shandong including Qingdao to Japan rather than returning sovereign authority to China. Chinese outrage over this provision ignited mass student demonstrations in Beijing on May 4th, 1919 which resulted in the cultural movement know today as the May Fourth Movement. The May 4th Movement influenced the Chinese delegation not to sign the Treaty of Versailles. China declared the end of its war against Germany in September 1919 and signed a separate treaty in 1921.
