 "O Uraguai" is set at the end of the Guaraní War and focuses on the slavery of the Guarani people imposed by the Society of Jesus (represented by the priest Balda), which contradicted the Catholic Church's own order.The poem is a noted example of Arcadianism and Indianism in eighteenth-century Brazilian Literature.This epic poem is considered, by most, unique because of the treatment given to the characters.
