Historiography of the May Revolution
Historiographical studies of the May Revolution started in the second half of the 19th century in Argentina and have extended to modern day. All historiographical perspectives agree in considering the May Revolution as the turning point that gave birth to the modern nation of Argentina, and that the Revolution was unavoidable in 1810. The main topics of disagreement between Argentine historians are the specific weight of the diverse causes of the May Revolution, who were the leaders of it among the different involved parties, whenever there was popular support for it or not, and whenever the loyalty to the captive Spanish king Ferdinand VII was real or an elaborate masquerade to conceal pro-independence purposes.
May Coup (Poland)
The May Coup ( or ) was a coup d'état carried out in Poland by Marshal Józef Piłsudski between 12 and 14 May 1926. The coup overthrew the government of President Stanisław Wojciechowski and Prime Minister Wincenty Witos. A new government was installed, headed by Lwów Polytechnic Professor Kazimierz Bartel. The events were partly inspired by the need for extraordinary measures in the face of newly emerging threats to the stability of Poland's independence by Piłsudski's own assessment of the foreign treaties signed by Weimar Germany with France in 1925 (fundamentally abandoning Poland) and with the Soviet Russia in April 1926, to which Poland's representatives had not been invited.
