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 Thirtieth Movement
The May Thirtieth Movement () was a major labor and anti-imperialist movement during the middle-period of the Republic of China era. It began when the British Shanghai Municipal Police opened fire on Chinese protesters in Shanghai's International Settlement on May 30, 1925 (the Shanghai massacre of 1925). The shootings sparked international censure and nationwide anti-foreign demonstrations and riots.
