The majority of present population of the Missões region first began to arrive in this area starting only over one hundred years ago.
Therefore, about three centuries after the original historical Jesuit missions had long vanished and what had been left of the native Christianized population had dispersed, reverting into their traditional semi-nomadic way of living.
The more recent settlements, in great part by transplanted by Europeans from old settlements on the eastern part of the state, brought with them their minority immigrant languages which are still in use today in greater or lesser extent throughout the countryside, in hamlets, towns and municipalities.
The municipality of Guarani das Missões was settled primarily by Polish immigrants, and the town still maintains its cultural and linguistic roots.
Campina das Missões is a municipality where the majority of its population has German background, however a substantial percentage of the inhabitants are descendant of Russian immigrants.
