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 Revolution
Historiographical studies of the May Revolution do not face many doubts or unknown details. Most of the information was properly recorded at the time and was made available to the public by the Primera Junta as patriotic propaganda. Because of this, historical views on the topic differ in their interpretations of the meanings, causes and consequences of the events, rather than in the accuracy of their depiction of the events themselves. The modern version of events does not differ significantly from the contemporary one.
The first people to write about the May Revolution were participants who wrote memoirs, biographies and diaries. However, their works were motivated by purposes other than historiographic ones, such as to explain the reasons for their actions, clean their public images, or express their support or rejection of the public figures and ideas of the time. For example, Manuel Moreno wrote the biography of his brother Mariano as propaganda for the revolutions in Europe, and Cornelio Saavedra wrote his autobiography at a moment when his image was highly questioned, to justify himself to his sons.
