Iberia is the Spanish peninsula so it refers to people from that region. My old dictionary speaks of an "Iberian race". Iberian also refers to those native to Portugal. But it gets confusing because the ancient Iberians were of the Caucasus region, which is east of Spain. But because the Caucasus is along the coast of the Black Sea, Iberia was accessible by sea. History gets confusing. REALLY confusing. My old dictionary states that the Iberians were "probably the ancestors of the modern Georgians". A country's boundaries change through the ages but today the tiny country of Georgia is just north of Turkey and Iran.
