28 de Julio: Independence day in Perù
Hoy, dìa de la Independencia!
Here how it's described in Wikipedia the process that brought Peru to its indipendence from the Spanish power.
The economic crisis favored the indigenous rebellion from 1780 to 1781. This rebellion was headed by Tupac Amaru II. At this time, the Napoleonic invasion of the Iberian Peninsula and the degradation of the Royal power took place. The Creole rebellion of Huánuco arose in 1812 and the rebellion of Cuzco arose between 1814 and 1816. These rebellions defended the liberal principles sanctioned by the Constitution of Cadiz of 1812.
Supported by the power of the Creole oligarchy, the Viceroyalty of Peru became the last redoubt of the Spanish dominion in South America. This Viceroyalty succumbed after the decisive continental campaigns of Simón Bolivar and Jose de San Martin. San Martin, who had displaced the realists of Chile after the magnificent battle of the Andes, and who had disembarked in Paracas in 1819, proclaimed the independence of Peru in Lima on July 28, 1821. Three years later, the Spanish dominion was eliminated definitively after the battles of Junín and Ayacucho. Its first elected president, however, was not in power until 1827.
