Editing Peru–Bolivian Confederation (section)

===Background===
{{See also|Salaverry-Santa Cruz War}}
At the beginning of the 19th century, [[Simón Bolívar]] postulated the idea of creating a great nation, coinciding with [[Andrés de Santa Cruz]], who thought of uniting [[Peru]] and [[Bolivia]] in a single country, the latter colloquially known as [[Upper Peru]]. The idea of uniting both countries was the general idea of several influential political leaders in Peru—including [[Francisco Xavier de Luna Pizarro]], {{ill|José María Pando|es}}, {{ill|Manuel Lorenzo de Vidaurre|es}}, [[Agustín Gamarra]], among others—who sought to reintegrate the two Perus, disagreeing only in the form of the “union”: confederation or merger. An important factor in the desire to unite these two states were the historical ties between both regions, even after independence.{{sfn|Tamayo|1985|page=252}}

After political instability and a coup d'état in 1835, a [[Salaverry-Santa Cruz War|civil war]] broke out between newly self-declared president [[Felipe Santiago Salaverry]] and constitutional president [[Luis José de Orbegoso]], who allowed Bolivian president [[Andrés de Santa Cruz]] to send his troops through the Peruvian border.{{sfn|Basadre|2014|page=93–115}} After the latter's triumph in 1836, assemblies were soon established to make way for the creation of the Confederation.
