25 de mayo | 2008/05/25
May 25, 1810. The May Revolution (in Spanish: Revolución de Mayo) was a series of political and social events in the nineteenth century city of Buenos Aires which installed the first local government not designated by the Spanish Crown in the Viceroyalty of the Río de la Plata, which at the time contained the present-day nations of Argentina, Bolivia, Paraguay and Uruguay. Although the Revolution took place only in Buenos Aires, one of the consequences was that the head of the Viceroyalty, Viceroy Cisneros, was ousted from office. Involved in these acts were mostly middle-high to high-class inhabitants of Buenos Aires (most native Spanish ex-patriates or residents of Spanish descent). There was no great violence involved; the term "revolution" has been loosely applied by Argentine tradition to highlight the changing of their governmental system and distinguish the undisputed fact that after the May Revolution, Buenos Aires itself was no longer subservient to decisions taken by Spain in their name.
