The Jê, who were called "Tabuis" (barbarian enemy) by the Tupi - Guarani
were forced to retreat to the highlands (plateaus) in the interior of the country.
About 1000 years ago, the Tupi - Guarani separated into two different linguistic groups:
the Tupi and the Guarani. The Tupi setteled from
Cananéia
(actual
State of São Paulo)
to the north, in the
southeast and northeast of Brazil and the Guaranis south of Cananéia in the
south.
Upon the arrival of the Portuguese and the
official
discovery
of Brazil by Pedro Álvares Cabral at
Mount Pascoal,
the different tribes were distributed as follows along Brazil's Atlantic coast:
in the south, between Lagoa dos Patos and Cananéia,
predominated the
Carijó (100.000), from there until Bertioga the
Tupiniquim (35.000),
from Bertioga to Cabo Frío the Tupinambá /
Tamoio / Temiminó (190.000) and in the south of Bahía at the
Discovery Coast,
again the Tupiniquim (50.000).
The different groups communicated in similar languages, which later were jointly
denominated as
tupi - guarani or
língua geral (common language)
by the
jesuit priests.
