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 Movement
The May Fourth Movement () was an anti-imperialist, cultural, and political movement growing out of student participants in Beijing on 4 May 1919, protesting against the Chinese government's weak response to the Treaty of Versailles, especially allowing Japan to receive territories in Shandong which had been surrendered by Germany after the Siege of Tsingtao. These demonstrations sparked national protests and marked the upsurge of Chinese nationalism, a shift towards political mobilization and away from cultural activities, and a move towards a populist base rather than intellectual elites. Many political and social leaders of the next decades emerged at this time.
