The Celts (usually pronounced  /ˈkɛlts/ but sometimes /ˈsɛlts/, see pronunciation of Celtic) or Kelts were an ethno-linguistic group of tribal societies in Iron Age and Medieval Europe who spoke Celtic languages and had a similar culture.^[1]

The earliest archaeological culture that may justifiably be considered as Proto-Celtic is the Late Bronze Age Urnfield culture of central Europe from the last quarter of the second millennium BC.^[2] Their fully Celtic^[2] descendants in central Europe were the people of the Iron Age Hallstatt culture (c. 800-450 BC) named for the rich grave finds in Hallstatt, Austria.^[3] By the later La Tène period (c. 450 BC up to the Roman conquest), this Celtic culture had expanded over a wide range of regions, whether by diffusion or migration: to the British Isles (Insular Celts), France and The Low Countries (Gauls), much of Central Europe, the Iberian Peninsula (Celtiberians, Celtici and Gallaeci) and northern Italy (Golaseccans and Cisalpine Gauls)^[4] and following the Gallic invasion of the Balkans in 279 BC as far east as central Anatolia (Galatians).^[5]

The earliest directly attested examples of a Celtic language are the Lepontic inscriptions, beginning from the 6th century BC.^[6] Continental Celtic languages are attested only in inscriptions and place-names. Insular Celtic is attested from about the 4th century in ogham inscriptions, although it is clearly much earlier. Literary tradition begins with Old Irish from about the 8th century. Coherent texts of Early Irish literature, such as the Táin Bó Cúailnge (The Cattle Raid of Cooley), survive in 12th-century recensions.

By mid 1st millennium AD, following the expansion of the Roman Empire and the Great Migrations (Migration Period) of Germanic peoples, Celtic culture and Insular Celtic had become restricted to Ireland, to the western and northern parts of Great Britain (Wales, Scotland, Cornwall and the Isle of Man), and to northern France (Brittany). Between the fifth and eighth centuries the Celtic-speaking communities of the Atlantic regions had emerged as a reasonably cohesive cultural entity. In language, religion, and art they shared a common heritage that distinguished them from the culture of surrounding polities.^[7] The Continental Celtic languages ceased to be widely used by the 6th century.

Insular Celtic culture diversified into that of the Gaels (Irish, Scottish and Manx) and the Brythonic Celts (Welsh, Cornish, and Bretons) of the medieval and modern periods. A modern "Celtic identity" was constructed in the context of the Romanticist Celtic Revival in Great Britain, Ireland, and other European territories, such as Galicia.^[8] Today Irish, Scottish Gaelic, Welsh, and Breton remain spoken in parts of their historical territories, and both Cornish and Manx are currently undergoing revival.

Names and terminology[link]

Galician Celtic Stele: Apana · Ambo/lli · f(ilia) · Celtica /Supertam(arica) · / [j] Miobri · /an(norum) · XXV · h(ic) · s(ita) · e(st) · /Apanus · fr(ater) · f(aciendum)· c(uravit)

The first recorded use of the word Celts (Κελτοί) to refer to an ethnic group was by Hecataeus of Miletus, the Greek geographer, in 517 BC,^[9] when writing about a people living near "Massilia" (Marseille).^[10] According to the testimony of Julius Caesar and Strabo, the Latin name "Celtus" (pl. "Celti" or "Celtae") and the Greek (Κέλτης pl. Κέλται or Κελτός pl. Κελτοί) were borrowed from a native Celtic tribal name.^[11][12] Pliny the Elder referred it as being used in Lusitania as a tribal surname^[13] which epigraphic findings confirm.^[14][15]

Latin "Gallus" might originally be from a Celtic ethnic or tribal name, perhaps borrowed into Latin during the Celtic expansions into Italy of the early 5th century BC. Its root may be the Common Celtic "*galno", meaning power or strength. Galli, Gallaeci and Galatae most probably go with Old Irish gal 'boldness, ferocity' and Welsh gallu 'to be able, power'.^[16] The Greek "Galatai" seems to be based on the same root, borrowed directly from the same hypothetical Celtic source which gave us "Galli" (the suffix "-atai" is an Ancient Greek inflection).^[17] (see Galatia in Anatolia)

The English word "Celt" is modern, attested from 1707 in the writings of Edward Lhuyd whose work, along with that of other late 17th-century scholars, brought academic attention to the languages and history of these early inhabitants of Great Britain.^[18] The English form "Gaul" (first recorded in the 17th century) and "Gaulish" come from the French "Gaule" and "Gaulois", which translate Latin "Gallia" and "Gallus, -icus" respectively. In Old French, the words "gualeis", "galois", "walois" (Northern French phonetics keeping /w/) had different meanings: Welsh or the Langue d'oïl, etc. On the other hand, the word "Waulle" (Northern French phonetics keeping /w/) is recorded for the first time in the 13th century to translate the Latin word Gallia, while "gaulois" is recorded for the first time in the 15th century, and the scholars use it to translate the Latin words Gallus / Gallicus. The word comes from Proto-Germanic *Walha- (see Gaul: Name). The English word "Welsh" originates from the word wælisċ, the Anglo-Saxon form of *walhiska-, the reconstructed Proto-Germanic word for "foreign"^[19] or "Celt" (South German Welsch(e) "Celtic speaker", "French speaker", "Italian speaker"; Old Norse "valskr", pl. "valir" "Gaulish", "French"), that is supposed to be derived of the name of the "Volcae",^[20] a Celtic tribe who lived first in the South of Germany and emigrated then to Gaul.^[21]

The notion of an identifiable Celtic cultural identity or "Celticity", though problematic, generally centres on language, art and classical texts,^[22] though can also include, material artifacts, social organisation, homeland and mythology.^[23] Earlier theories were that this indicated a common racial origin but more recent theories are reflective of culture and language rather than race. Celtic cultures seem to have had numerous diverse characteristics but the commonality between these diverse peoples was the use of a Celtic language.^{[citation needed]}.

"Celtic" is a descriptor of a family of languages and, more generally, means "of the Celts", or "in the style of the Celts". It has also been used to refer to several archaeological cultures defined by unique sets of artifacts. The link between language and artifact is aided by the presence of inscriptions.^[24] (see Celtic (disambiguation) for other applications of the term)

Today, the term Celtic is generally used to describe the languages and respective cultures of Ireland, Scotland, Wales, Cornwall, the Isle of Man and Brittany, also known as the Six Celtic Nations. These are the regions where four Celtic languages are still spoken to some extent as mother tongues: Irish Gaelic, Scottish Gaelic, Welsh, and Breton, plus two recent revivals, Cornish (one of the Brythonic languages) and Manx (one of the Goidelic languages). There are also attempts to reconstruct the Cumbric language (a Brythonic language from North West England and South West Scotland). 'Celtic' is also sometimes used to describe regions of Continental Europe that claim a Celtic heritage, but where no Celtic language has survived; these areas include the western Iberian Peninsula, i.e. Portugal, and north-central Spain (Galicia, Asturias, Cantabria, Castile and León, Extremadura).^[25] (see Modern Celts)

"Continental Celts" refers to the Celtic-speaking people of mainland Europe. "Insular Celts" refers to the different Celtic-speaking peoples of the British and Irish islands and to their descendants. The Celts of Brittany derive their language from migrating insular Celts mainly from Wales and Cornwall and so are grouped accordingly.^[26]

The territories of some major Celtic tribes of the late La Tène period are labelled.

The Celtic languages form a branch of the larger Indo-European family. By the time speakers of Celtic languages enter history around 400 BC, they were already split into several language groups, and spread over much of Western continental Europe, the Iberian Peninsula, Ireland and Britain.

Some scholars think that the Urnfield culture of Western Middle Europe represents an origin for the Celts as a distinct cultural branch of the Indo-European family.^[2] This culture was preeminent in central Europe during the late Bronze Age, from ca. 1200 BC until 700 BC, itself following the Unetice and Tumulus cultures. The Urnfield period saw a dramatic increase in population in the region, probably due to innovations in technology and agricultural practices. The Greek historian Ephoros of Cyme in Asia Minor, writing in the 4th century BC, believed that the Celts came from the islands off the mouth of the Rhine and were "driven from their homes by the frequency of wars and the violent rising of the sea".

The spread of iron-working led to the development of the Hallstatt culture directly from the Urnfield (ca. 700 to 500 BC). Proto-Celtic, the latest common ancestor of all known Celtic languages, is considered by this school of thought to have been spoken at the time of the late Urnfield or early Hallstatt cultures, in the early 1st millennium BC. The spread of the Celtic languages to Iberia, Ireland and Britain would have occurred during the first half of the 1st millennium BC, the earliest chariot burials in Britain dating to c. 500 BC. Other scholars see Celtic languages as covering Britain and Ireland, and parts of the Continent, long before any evidence of "Celtic" culture is found in archaeology. Over the centuries the language(s) developed into the separate Celtiberian, Goidelic and Brythonic languages.

The Hallstatt culture was succeeded by the La Tène culture of central Europe, which was overrun by the Roman Empire, though traces of La Tène style are still to be seen in Gallo-Roman artefacts. In Britain and Ireland La Tène style in art survived precariously to re-emerge in Insular art. Early Irish literature casts light on the flavour and tradition of the heroic warrior elites who dominated Celtic societies. Celtic river-names are found in great numbers around the upper reaches of the Danube and Rhine, which led many Celtic scholars to place the ethnogenesis of the Celts in this area.

Diodorus Siculus and Strabo both suggest that the Celtic heartland was in southern France. The former says that the Gauls were to the north of the Celts but that the Romans referred to both as Gauls. Before the discoveries at Hallstatt and La Tene, it was generally considered that the Celtic heartland was southern France, see Encyclopædia Britannica for 1813.

Linguistic evidence[link]

The Proto-Celtic language is usually dated to the Late Bronze Age.^[2] The earliest records of a Celtic language are the Lepontic inscriptions of Cisalpine Gaul, the oldest of which still predate the La Tène period. Other early inscriptions are Gaulish, appearing from the early La Tène period in inscriptions in the area of Massilia, in the Greek alphabet. Celtiberian inscriptions appear comparatively late, after about 200 BC. Evidence of Insular Celtic is available only from about 400 AD, in the form of Primitive Irish Ogham inscriptions. Besides epigraphical evidence, an important source of information on early Celtic is toponymy.^[27]
