1810. May Revolution.

The May Revolution (Spanish: Revolución de Mayo) was a week-long series of events that took place from May 18 to 25, 1810, in Buenos Aires, capital of the Viceroyalty of the Río de la Plata, a Spanish colony that included roughly the territories of present-day Argentina, Bolivia, Paraguay and Uruguay. The result was the removal of Viceroy Baltasar Hidalgo de Cisneros and the establishment of a local government, the Primera Junta (First Junta), on May 25. These events are commemorated in Argentina as "May Week" (Spanish: Semana de Mayo).
