Dissolution of the Peru–Bolivian Confederation

The dissolution of the Peru–Bolivian Confederation was the process of internal disintegration within the Peru–Bolivian Confederation which resulted in the end of the country's and its confederate government's existence as a sovereign state, being succeeded by Bolivia and a unified Peruvian state.

The disintegration was related to the conflict of interest between the Confederation and the Republic of Chile, as well as the friction inherited by the Bolivian side with the latter. Unlike Gran Colombia, which was created in 1819 and disappeared in 1831, the dissolution of the Confederation was marked by a certain tranquility and tolerance for a certain period of one year when Agustín Gamarra himself began his military campaign in Bolivian territory, resulting in his death and the signing of the Treaty of Puno, which put an end to all ideas of union, annexation, confederation or federation between the two countries at least during the beginning of the 19th century.
