The earliest inhabitants of Spain were Berbers from North Africa. Around 2000 BC, tribe called the "Iberians" migrated from the Caucasus. Then shortly after, the Scythians invaded and conquered most of Spain. The Tartessians, a tribe of Greek and Phoenician ancestry, also settled there. Later, the Celts piled in and mixed with the native Iberians. Other invasions followed... Phoenicians, Romans, Visigoths, and Moors.
