The ethnic and linguistic affiliation (Paleo-Sardinian language) of the Nuragic people and tribes remains to be further studied, moreover "Nuragic" might have also been a geographical and historical name designating different peoples and languages, rather than indicating a single origin. Current knowledge indicates that they may have been related to the Iberians and the ancient Basque: these peoples were Pre-Indo-Europeans and spoke Pre-Indo-European languages, Proto-Basque (the ancestor of modern Basque) and Iberian. There is also the possibility that the Nuragic peoples may have been related to the Etruscans and other Tyrsenian peoples and languages. One of the Sea Peoples (the Shardana or Sherden) may have been either a population hailing from Sardinia (Ugas 2005, 2016) or a group of tribes that migrated to the island in the Late Bronze Age (Sandars 1978).
