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
The ideals of the French Revolution of 1789 spread across Europe and the Americas as well. The overthrow and execution of King Louis XVI and Queen Marie Antoinette ended centuries of monarchy and removed the privileges of the nobility. Liberal ideals in the political and economic fields developed and spread through the Atlantic Revolutions across most of the Western world. The concept of the divine right of kings was questioned by the French "Declaration of the Rights of Man and of the Citizen", by the oft-quoted statement that "all men are created equal" in the United States Declaration of Independence and even by the Spanish church.
