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 Manifesto
Continuing into 1924, the secret negotiations between the Federalists, BCP and IMRO representatives were conducted to unite all groups under the same goal: the independence or autonomy of a Macedonian state. In May 1924 party leaders Alexandrov, Protogerov and Petar Chaulev issued a new manifesto about the new orientation of the Macedonian Revolutionary Movement. This communist-influenced document reads as an excuse for a Macedonian state for the silliest of reasons: "endowed with the most varied natural riches and a favorable climate; with its ethnically diverse population of upwards of 2,302,000 persons; with a strategic and economic position in the middle of the Balkans [...] has all the rights and conditions necessary for an independent political existence. Forming an independent and self governing state". Once again the IMRO explicitly states Macedonia is multi-ethnic. It also declares its goal to be the "liberation and reunion of the separated parts of Macedonia in a fully autonomous and independent political unit within its natural geographic and ethnic frontiers". The new position of the IMRO was identical to that of the Balkan Communist Federation and won for the BCP the endorsement of its policy by the Comintern at its fifth congress that summer. The Congress considered the slogans formulated by the sixth Balkan Communist Federation Conference: "United Independent Macedonia" and "United Independent Thrace" wholly correct and truly revolutionary.
