====Conflict with Bolivia and Colombia====
[[José de La Mar]] became president of Peru on August 22, 1827, having been chosen by the new Congress.<ref>{{Cite web |title=José de La Mar Cortázar |url=https://adonde.com/historia/1822pres_lamar.htm |access-date=2022-12-01 |website=adonde.com}}</ref><ref>{{Cite web |date=2019-07-08 |title=José de La Mar (periodo: 1827 – 1829) |url=https://historiadelperu.info/presidentes-del-peru/jose-de-la-mar/ |access-date=2022-12-01 |language=es}}</ref> Under his presidency, Peru went to war with Bolivia and Colombia due to the perceived disadvantage that Peru saw itself in due to being surrounded by Bolivarian countries.

A Peruvian [[1828 Peruvian–Bolivian War|invasion of Bolivia]] headed by [[Agustín Gamarra]] began on May 1, 1828.<ref>{{Cite web |date=2019-09-05 |title=Intervención peruana en Bolivia (primera invasión peruana - 1828) |url=https://www.ibolivia.org/intervencion-peruana-en-bolivia-1828 |access-date=2022-12-01 |website=Portal iBolivia |language=es}}</ref> The Peruvian Army soon occupied the Bolivian [[La Paz Department (Bolivia)|department of La Paz]], established a [[Republic of Alto Perú|pro-Peruvian government]] and successfully deported the Colombian troops stationed in the country via ships paid by Bolivia that departed from the Peruvian port of [[Arica]].

The events in Bolivia led to [[Gran Colombia–Peru War|war between Peru and Colombia]], which ended with the [[Battle of Tarqui]] on February 27, 1829, after which an armistice was signed. The breach of the armistice almost led to a continuation of the war, an event that was prevented by the political instability in Peru that led to the deposition of La Mar by [[Agustín Gamarra]], who signed [[Treaty of Guayaquil|a peace treaty]] with Colombia.
