In 1835, the revolt known as Cabanagem began in the province of Grão-Pará (Brazil), in which blacks, indigenous people, and mestizos rose up against the political elite and took power. The documentary Cuipiranga is a quest to record the testimonies of the descendants, in the lower Tapajós region, of this revolt that is considered the first popular insurrection that went from simple agitation to an effective seizure of power.
