Independence and subsequent wars

The struggle for independence started in 1809, and after 16 years of war the republic was proclaimed on August 6, 1825, named for Simón Bolívar.

In 1836, Bolivia, under the rule of Marshal Andrés de Santa Cruz, invaded Peru to reinstall the deposed president, General Luis José de Orbegoso. Peru and Bolivia formed the Peru-Bolivian Confederation, with de Santa Cruz as the Supreme Protector. Following tension between the Confederation and Chile, Chile declared war on December 28, 1836. Argentina, Chile's ally, declared war on the Confederation on May 9, 1837. The Peruvian-Bolivian forces achieved several major victories during the War of the Confederation: the defeat of the Argentinian expedition and the defeat of the first Chilean expedition on the fields of Paucarpata near the city of Arequipa.

On the same field the Paucarpata Treaty was signed with the unconditional surrender of the Chilean and Peruvian rebel army. The treaty stipulated that Chile withdraw from Peru-Bolivia, return captured Confederate ships, economic relations would be normalized, and the Confederation would pay Peruvian debt to Chile. Public outrage over the treaty forced the government to reject it. Chile organized a second attack on the Confederation and defeated it in the Battle of Yungay. After this defeat, Santa Cruz fled to Ecuador, and the Peruvian-Bolivian Confederation was dissolved.

Following the independence of Peru, Peruvian president General Agustín Gamarra invaded Bolivia. The Peruvian army was decisively defeated at the Battle of Ingavi on November 20, 1841, where Gamarra was killed. The Bolivian army under General José Ballivián then mounted a counter-offensive managing to capture the Peruvian port of Arica. Later, both sides signed a peace treaty, the Declaration of Independence of Bolivia, in 1842, putting a final end to the war.
