In 1910, the families of Zeferino Gotardi, Jorge Galvão, Paschoal Proto, Gasparo Traldi and Luís Guilhermitti left São Joaquim da Barra, São Paulo, to settle in this region for its fertile soil which allowed for better farming. The name "Aliança" was chosen because the founders were originally from a farm called "Bela Aliança".
In the early twentieth century, the town of Monte Belo in the region faced rapid growth, most of which was in the agricultural sector. The population reached an estimated 500 inhabitants and urban development including homes and judicial buildings. The growth was soon interrupted by a malaria epidemic that killed many people.
The municipality was created by state law in 1944.[3]
