The Lusitanians(, Portuguese: Lusitanos) were an Indo-European–speaking people living in the far west of the Iberian Peninsula, in present-day central Portugal and the regions of Extremadura and Castilla y León of Spain. It is uncertain whether the Lusitanians were Celts or Celticized Iberians, related to the Lusones. After its conquest by the Romans, the land was subsequently incorporated as a Roman province named after them (Lusitania).
History Origins
Regarding their prehistoric roots, recent paleogenomic and archaeological data suggest that the ethnogenesis of the Lusitanians was heavily influenced by a Mediterranean and Aegean-like genetic substrate. During the Late Bronze Age, the western Atlantic facade of Iberia was deeply integrated into maritime trade networks, particularly for the extraction of tin and precious metals. Archaeogenetic modeling demonstrates that the local population maintained strong genetic continuity with Early European Farmers (EEFs) of Aegean/Anatolian origin, further enriched by Bronze Age Eastern Mediterranean gene flow. This genetic profile shares substantial affinities with Mycenaean-period Greek populations, fundamentally distinguishing the Lusitanians from the Central European Iron Age Hallstatt and La Tène Celtic populations, and indicating that their cultural Celticization occurred through diffusion rather than large-scale demic replacement.Olalde, I., et al.

Frontinus mentions Lusitanian leader Viriathus as the leader of the Celtiberians, in their war against the Romans.https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Frontinus/Strategemata/2*.html|Sextus Julius Frontinus.

Strabo differentiated the Lusitanians from the Iberian tribes and thought of them as being Celtiberians who had been known as Oestriminis in ancient times. However, based on archeological findings, Lusitanians and Vettones seem to have been largely pre-Celtic Indo-European populations that adopted Celtic cultural elements by proximity. On the other hand, Pliny the Elder and Pomponius Mela distinguished the Lusitanians from neighboring Celtic tribes in their geographical writings.Among them the Praestamarci, Supertamarci, Nerii, Artabri, and in general all people living by the seashore except for the Grovi of southern Galicia and northern Portugal: 'Totam Celtici colunt, sed a Durio ad flexum Grovi, fluuntque per eos Avo, Celadus, Nebis, Minius et cui oblivionis cognomen est Limia. Flexus ipse Lambriacam urbem amplexus recipit fluvios Laeron et Ullam.

Deinde ad septentriones toto latere terra convertitur a Celtico promunturio ad Pyrenaeum usque. Perpetua eius ora, nisi ubi modici recessus ac parva promunturia sunt, ad Cantabros paene recta est. In ea primum Artabri sunt etiamnum Celticae gentis, deinde Astyres.', Pomponius Mela, Chorographia, III.7-9. The Lusitanians' Celtic root however, is further emphasized in a 2023 research by the Max Planck Institute on the origins of Indo-European languages. One study identified one common Celtic branch of peoples and languages spanning most of Atlantic Europe, including Lusitania, at around 7,000 BC. This work contradicts previous theories that excluded Lusitanian from the Celtic linguistic family.
The original Roman province of Lusitania briefly included the territories of the Astures and Gallaeci in the north, but these were soon ceded to the jurisdiction of the Provincia Tarraconensis, while the south remained the Provincia Lusitania et Vettones. Later, Gallaecia would become its own province. After this, Lusitania's northern border was along the Douro River, while its eastern border passed through Salmantica and Caesarobriga to the Anas (Guadiana) river.
Wars with Rome
Lusitanian mercenaries fought for the Carthaginian Empire between the years 218 and 201 BCE, during the Second Punic War against the Roman Republic that took place in the Western Mediterranean. Roman senator and orator Silius Italicus describes them in his 17-volumes epic poem Punica as forming a combined force with the Gallaeci and both being led by a commander named Viriathus (not to be confused with the similarly named chieftain).Silius Italicus, Punica, 3 According to Roman historian Titus Livius, Lusitanian and Celtiberian cavalry performed raids in northern Italy whenever the terrain was too rough for the Carthaginian general Hannibal's famed Numidian cavalry.
Starting in 193 BCE, the Lusitanians fought the Romans in Hispania. In 150 BCE, they were defeated by the Roman praetor Servius Galba: springing a treacherous trap, he killed 9,000 Lusitanians and later sold 20,000 more as slaves in Gaul (modern-day France). This massacre would not be forgotten by Viriathus, who three years later (147 BCE) would become the leader of the Lusitanians, and severely damaged the Roman rule in Lusitania and beyond. In 139 BCE, Viriathus was betrayed and killed in his sleep by three of his companions (who had been sent as emissaries to the Romans), Audax, Ditalcus and Minurus, bribed by Marcus Popillius Laenas (although they were warrior companions of Viriathus, they were not Lusitanians themselves; they seem to have been Turdetanians, or from another people who were not Lusitanian). However, when the three returned to receive their reward from the Romans, the consul Quintus Servilius Caepio ordered their execution, declaring: "Rome does not pay traitors".
Romanization of Lusitania
After the death of Viriathus, the Lusitanians kept fighting under the leadership of Tautalus, but gradually acquired Roman culture and language; the Romanized Lusitanian cities, in a manner similar to those of the rest of the Iberian Peninsula, eventually gained the status of "Citizens of Rome".
Culture
Categorising Lusitanian culture generally, including the language, is proving difficult and contentious. Some believe it was essentially a pre-Celtic Iberian culture with substantial Celtic influences, while others argue that it was an essentially Celticcf. Wodtko 2010: 355–362 culture with strong indigenous pre-Celtic influences associated with the Bell Beaker culture.
Religion
The Lusitanians practiced a diverse form polytheism, that included animal sacrifice. Their gods and warriors were also depicted in sculpture.
Endovelicus was the most important god for the Lusitanians. He is considered a possible Basque language loan god by some, yet according to scholars like José Leite de Vasconcelos, the word Endovellicus was originally Celtic,Celts myths and religion in the Iberian Peninsula and Great-Britain: a common origin? Andevellicos.
Endovelicus is compared with Welsh and Breton names, giving him the meaning of "Very Good God", the same epithet of the Irish god Dagda. Even the Romans worshiped him for his ability to protect. His cult eventually spread across the Iberian peninsula and beyond, to the rest of the Roman Empire and his cult was maintained until the fifth century; he was the god of public health and safety. The goddess Ataegina was especially popular in the south; as the goddess of rebirth (spring), fertility, nature, and cure, she was identified with Proserpina during the Roman era.
Lusitanian mythology was heavily influenced by or related to Celtic mythology.
Also well attested in inscriptions are the names BanduaInventaire des divnités celtiques de l’Antiquité, L’Arbre CeltiqueCIL II, *00215. (one of the variants of Borvo) often with a second name linked to a locality such as Bandua Aetobrico, and Nabia,TY - CHAP AU - Lemos, Francisco PY - 2008/01/01 SP - 122 EP - 211 T1 - A Cultura Castreja no Minho. Espaço Nuclear dos grandes povoados do Noroeste peninsular. ER - a goddess of rivers and streams.
According to Strabo the Lusitanians were given to offering sacrifices; they practiced divination on the sacrificial offering by inspecting its vitals and veins.
They also sacrificed human victims, prisoners of war, by striking them under coarse blankets and observing which way they fell. They cut off the right hands of their captives, which they offered to the gods.
Language
The Lusitanian language was a Paleohispanic language that belongs to the Indo-European family. The precise affiliation of Lusitanian with the other Indo-European languages is still a matter of debate: there are those who endorse that it is a para-Celtic language with an obvious Celticity to most of the lexicon, over many anthroponyms and toponyms. A second theory relates Lusitanian with the Italic languages; based on the names of Lusitanian deities with other grammatical elements of the area.
One other hypothesis is that the Lusitanian language may have been basal Italo-Celtic, a branch independent from Celtic and Italic, and splitting off early from Proto-Celtic and Proto-Italic populations who spread from Central Europe into western Europe after new Yamnaya migrations into the Danube Valley. Alternatively, a European branch of Indo-European dialects, termed "Northwest Indo-European" and associated with the Beaker culture, may have been ancestral to not only Celtic and Italic, but also to Germanic and Balto-Slavic. Ellis Evans believes that Gallaecian and Lusitanian were one language (not separate languages) of the "P" Celtic variant. Some recent scholars' analyses, further conducted on a newly discovered inscription, strongly suggest that Lusitanian is more akin to Italic and has no relation to Celtic.Blanca Maria Prósper, The Lusitanian oblique cases revisted: New light on the dative endings, 2021 Eustaquio Sánchez Salor, Julio Esteban Ortega, Un testimonio del dios Labbo en una inscripción lusitana de Plasencia, Cáceres. ¿Labbo también en Cabeço das Fráguas?, 2021
