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.

These protests, now known as the May Fourth Movement, has been widely regarded as one of the most important turning points in modern China's history. In its broader sense, the May Fourth Movement led to the establishment of radical Chinese intellectuals who went on to mobilize peasants and workers into the Communist party and gain the organizational strength that would solidify the success of the Communist Revolution.
