The Hispanic Peninsula immediately prior to Romanization was occupied by numerous tribes or clans representing diverse Indo-European and non-Indo-European populations. Basques resided in the north, Celts in the northwest and central regions, Tartessians in the south, Bastetanians in the southeast and Iberians in the east and northeast.
The region of the Iberians, extending from a little north of the Pyrenees south to Alicante and beyond, has consistently yielded a number of inscriptions in a language thus far unrelated to the other known languages of the Peninsula, or to the undeciphered languages underlying the inscriptions of the south. Iberian, a geographical and collective term, refers to the several cultures and dialects which appear connected in unknown degrees to two major groups: the Edetanos of the Valencian plains and the related Ilergetes who dwelt further north in Catalufña.
