Peru–Bolivian Confederation

The Peru–Bolivian Confederation (Spanish: Confederación Perú–Boliviana) was a short-lived state that existed in South America between 1836 and 1839. The country was a loose confederation made up of three states: North Peru, South Peru, and the Bolivian Republic. North Peru and South Peru had emerged from the division of the Peruvian Republic due to the Peruvian Civil War of 1834 and the Salaverry-Santa Cruz War of 1835–36.

The geographical limits of the Confederation varied over time, with Bolivia occupying and incorporating certain disputed territories in northern Argentina in 1838. It also possessed de facto autonomous indigenous territories, such as Iquicha, all under the supreme command of Marshal Andrés de Santa Cruz, who assumed the position of Supreme Protector in 1836, while he was president of Bolivia.
