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
Juan Bautista Alberdi and later historians such as Norberto Galasso, Luis Romero and José Carlos Chiaramonte doubted Mitre's interpretation and put forward different ones. Alberdi thought that "the Argentine revolution is a chapter of the Hispanoamerican revolution, as also of the Spanish one, as also of the French and European one". They did not consider it a dispute between independentism and colonialism, but instead a dispute between new libertarian ideas and absolutism. The intention was not to cut ties with Spain, but to reformulate the relationship; similarly, the American Revolution was not separatist at its initial steps either. Thus, it would have the characteristics of a civil war instead. Some points that would justify the idea would be the inclusion of Larrea, Matheu, and Belgrano in the Junta and the later appearance of José de San Martín: Larrea and Matheu were Spanish, Belgrano studied for many years in Spain, and San Martín had spent most of his adult life waging war in Spain against the French. When San Martín talked about enemies, he called them "royalists" or "Goths", but never "Spanish".
