Some examples of these tribes are: Tupiniquim, Tupinambá, Potiguara, Tabajara, Caetés, Temiminó, Tamoios. The Tupi were adept agriculturalists; they grew cassava, corn, sweet potatoes, beans, peanuts, tobacco, squash, cotton and many others. There was not a unified Tupi identity [citation needed] despite the fact that they spoke a common language.
