May Revolution
The May Revolution was a direct reaction to Spain's Peninsular War. In 1808, King Ferdinand VII of Spain abdicated in favor of Napoleon, who granted the throne to his brother, Joseph Bonaparte. A Supreme Central Junta led resistance to Joseph's government and the French occupation of Spain, but eventually suffered a series of reversals that resulted in the Spanish loss of the northern half of the country. On February 1, 1810, French troops took Seville and gained control of most of Andalusia. The Supreme Junta retreated to Cadiz and dissolved itself, and the Council of Regency of Spain and the Indies replaced it. News of these events arrived in Buenos Aires on May 18, brought by British ships.
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.
