Legacy of the May Revolution

The May Revolution (Spanish: Revolución de Mayo) was a week-long series of revolutionary events that took place from May 18 to May 25, 1810, in Buenos Aires. It started the Argentine War of Independence, and it is considered the birth of modern Argentina.

May 25 is a patriotic date in Argentina, known as First Patriotic Government, with the character of a national holiday. The holiday is set by law 21.329 and it is immovable, meaning it is celebrated exactly on May 25 regardless of day of the week. The Bicentennial of Argentina was celebrated in 2010.

May 25 was designated as a patriotic date in 1813, but the Argentine Declaration of Independence provides an alternative national day. In the beginning, this added to the conflicts between Buenos Aires and the provinces during the Argentine Civil War, because the date in May related to Buenos Aires and the date of July 9 related to the whole country. As a result, the unitarian Bernardino Rivadavia canceled the celebration of July 9, and the federalist Juan Manuel de Rosas re-allowed it, but without giving up celebrations in May. By 1880, with the federalization of Buenos Aires, the local connotations were removed and the May Revolution was considered the birth of the nation.

The date, as well as a generic image of the Buenos Aires Cabildo, are used in different variants to honor the May Revolution. Two of the most notable are the Avenida de Mayo and the Plaza de Mayo at Buenos Aires, near the location of the Cabildo. The Pirámide de Mayo was erected in the Plaza a year after the revolution, and was rebuilt to its present form in 1856. "May 25" (in Spanish, "Veinticinco de Mayo") is the name of several administrative divisions, cities, public spaces, and landforms of Argentina. There are departments of this name in the provinces of Chaco, Misiones, San Juan, Rio Negro, and Buenos Aires, the latter one holding the Veinticinco de Mayo city. The cities of Rosario (Santa Fe), Junín (Buenos Aires), and Resistencia (Chaco) have eponymous squares. The King George Island is under sovereignty claims of Argentina, Britain, and Chile, as part of the Argentine Antarctica, British Antarctic Territory, and Chilean Antarctic Territory, with Argentina naming it "Isla 25 de Mayo".
