 The name spelling was changed into "Chavantes" in 1982.The railway was soon transferred further northwest with connections with Ourinhos, which despite being founded later than Chavantes, became more prominent, perhaps due to its strategic situation closer to the great Northern Paraná coffee farms.Chavantes became officially autonomous on December 4, 1922, but its exploration history goes back to the 1870s and probably before that, with the Portuguese Bandeiras settling campaigns that sought to expand Portuguese lands beyond the Tordesilhas Treaty landmark with Spanish America, while attempting to enslave the Natives in a colonialist search for precious stones.
