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.
Historiography of the May Revolution
The 150º anniversary of the May Revolution found the liberal and revisionist historiographies opposing each other more strongly. The senator from Corrientes J. Aníbal Dávila promoted the republication of old documents so that ""the intentions of the antihistory of Argentina does not confuse the current generations, the masses and the youth with misleading slogans"". José María Rosa would react by stating that the Revolution was carried out by the masses and that those were shadowed by other figures by liberal historians seeking to falsify history. The perspectives of Rosa found great acceptance in society and are currently part of the Argentine historic common sense.
