The Paraná Campaign was the continuation of the São Paulo Revolt of 1924 in western Paraná from 1924 to 1925, concluding with the formation of the Miguel Costa-Prestes Column. Rebel tenentists, led by Isidoro Dias Lopes, withdrew from São Paulo, went down the Paraná River and settled in the region from Guaíra to Foz do Iguaçu, from where they faced the forces of the Brazilian government, commanded by general Cândido Rondon from October 1924. In April 1925, another rebel column, led by Luís Carlos Prestes, arrived from Rio Grande do Sul and joined the São Paulo rebels. They entered Paraguay to escape the government siege and returned to Brazil through southern Mato Grosso, continuing their armed struggle.

The São Paulo Revolt of 1924 was a Brazilian conflict with characteristics of a civil war, triggered by tenentist rebels to overthrow the government of president Artur Bernardes. Initially started in the city of São Paulo on 5 July, the revolt expanded to the interior of the state and inspired other uprisings across Brazil. The urban combat ended in a loyalist victory on 28 July. The rebels' withdrawal, until September, prolonged the rebellion with the Paraná Campaign.
