Ygana
Ygañá was a Guaraní regional grouping on the upper Paraná, in the country where the Jesuit reduction of Corpus was later established. Guaraní communities cultivated crops in forest clearings and travelled along the river and its tributaries. From the seventeenth century, Jesuit missions brought some communities into new settlements along the Paraná, while raids by slave hunters threatened the peoples of the wider Guairá region.
