May Revolution
The May Revolution was not the product of the actions of a single political party with a clear and defined agenda, but a convergence of sectors with varying interests. Thus, there are a number of conflicting perspectives about it, because different authors highlight different aspects. Mitre, for example, referred to "The Representation of the Landowners" (an 1809 economic report by Mariano Moreno) and the role of the merchants to support the view that the May Revolution intended to obtain free trade and economic integration with Europe; right-wing revisionists center around Saavedra and the social customs of the time to describe the revolution under conservative principles; and left-wing revisionists use the example of Moreno, Castelli and the rioters led by French and Beruti to describe it as a radical revolution.
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.
