Bolivia gets it independence from Spain.

The Bolivian war of independence began in 1809 with the establishment of Spanish American Independence. Sucre and La Paz, after the Chuquisaca Revolution. These Juntas were defeated shortly after, and the cities fell again under Spanish control. The May Revolution of 1810 ousted the viceroy in Buenos Aires, which established its own junta. Buenos Aires sent three military campaigns to the Charcas, headed by Juan José Castelli and José Rondeau”, but the royalists ultimately prevailed over each one. However, the conflict grew into a Guerrilla warfare, preventing the royalists from strengthening their presence. After Simón Bolívar and Antonio José de Sucre defeated the royalists in northern South America, Sucre led a campaign that was to defeat the royalists in Charcas for good when the last royalist general, Pedro Antonio Olañeta, suffered death and defeat at the hands of his own defected forces at the battle of Tumusla. Bolivian independence was proclaimed on August 6 of 1825.

The deliberating Assembly convened anew in Chuquisaca on 9 July 1825. It concluded with the determination of the complete independence of Upper Peru, in the form of a republic, for the sovereignty of its children. Finally, the president of the Assembly – José Mariano Serrano – and a commission wrote the “Act of Independence”, which bears the date 6 August 1825 in honor of the Battle of Junín won by Bolívar.

The Act of Independence’s introduction says, in a vibrant voice: The world knows that Upper Peru has been on the American continent, the altar on which was spilled the first blood of the free and the land where exists the tomb of the last of the tyrants…The provinces of Upper Peru, united in resolution, proclaim on the face of the whole earth, that their irrevocable resolution is to govern themselves.
