Foundation of the Phoenician colony of Gadir (modern Cádiz) near Tartessos. Contrary to myth, there is no record of Phoenician colonies west of the Strait of Gibraltar, even though there might have been some voyages of discovery. Phoenician influence in what is now Portuguese territory was done through cultural and commercial exchange with Tartessos.
Phoenicians introduce in Iberia the use of Iron, of the Potter's wheel, the production of Olive oil and Wine. They were also responsible for the first forms of Iberian writing, had a big religious influence and accelerated urban development.
There are organized settlements in Olissipona (modern Lisbon, in PortugueseEstremadura) with clear Mediterranean influences. The myth of a Phoenician foundation of the city as far back as 1300 BC, under the name Alis Ubbo ("Safe Harbour") is not true
Cultural shift in southern Portuguese territory after the fall of Tartessos, with a strong Mediterranean character that prolonges and modifies Tartessian culture. This occurs mainly in Low Alentejo and the Algarve, but has littoral extensions up to the Tagus mouth (namely the important city of Bevipo, modern Alcácer do Sal).
First form of writing in western Iberia (south of Portugal), the Southwest script (still to be translated), denotes strong Tartessian influence in its use of a modified Phoenician alphabet. In these writings the word Conii (similar to Cunetes or Cynetes, the people of the Algarve) appears frequently.
The poem Ora Maritima, written by Avienus in the 4th century and based on the Massaliote Periplus of the 6th Century BC, states that all of western Iberia was once called for the name of its people, the Oestriminis, which were replaced by an invasion of the Saephe or Ophis (meaning Serpent). From then on western Iberia would have been know as Ophiussa (Land of the Serpents).The poem also describes the various ethnic groups present at that time:
The Cynetes or Cunetes in the extreme south and some cities along the Atlantic coast (such as Olissipo, modern Lisbon), probably not Indo-European, but autochthonous Iberian (even if strongly or totally celticized over the next centuries).
The Lusitanians (most probably proto-Celt) inhabit the area between the Douro and the Tagus rivers (and progressively penetrate the High Alentejo). They are neighbored to the east by the Vettones (also probably proto-Celt).
