Peru-Bolivia (Unitatis)

Peru-Bolivia (Spanish: Perú-Bolivia), officially the Peru-Bolivian Confederation, is a country in western South America. It is bordered in the north by Colombia, in the east by Brazil, and in the south by Argentina.

The country came to be after the unification of the short-lived states of Peru and Bolivia, which had both declared independence from the Spanish Empire in the 1820s. Argentina and the Republic of Chile (now part of Argentina) strongly opposed the confederation due to its potential power, and attempted to destroy the new nation in the War of the Confederation but failed. Conflict later broke out with Colombia and Brazil due to border disputes.

Peru-Bolivia is a confederal presidential republic comprised of three constituent republics; North Peru, South Peru, and Bolivia. The country is further divided into departments.
