Initially inhabited by the Maracás Indians, the actual occupation occurred during the golden times of mineral prospection, from 1710, when gold was found near Contas River, marking the arrival of the explorers. In 1844, the colonization was boosted by the discovery of valuable diamonds in the surroundings of Mugugê River, and the traders, settlers, Jesuit priests and foreigners that lived in the villages controlled and regulated by the power of wealth.
