La Tène culture in the context of "Gaul"

The Celts (/kɛlts/ KELTS, see pronunciation for different usages) or Celtic peoples (/ˈkɛltɪk/ KEL-tik) were a collection of Indo-European peoples in Europe and Anatolia, identified by their use of Celtic languages and other cultural similarities. Major Celtic groups included the Gauls; the Celtiberians and Gallaeci of Iberia; the Britons, Picts, and Gaels of Britain and Ireland; the Boii; and the Galatians. The interrelationships of ethnicity, language and culture in the Celtic world are unclear and debated; for example over the ways in which the Iron Age people of Britain and Ireland should be called Celts. In current scholarship, 'Celt' primarily refers to 'speakers of Celtic languages' rather than to a single ethnic group.

The history of pre-Celtic Europe and Celtic origins is debated. The traditional "Celtic from the East" theory, says the proto-Celtic language arose in the late Bronze Age Urnfield culture of central Europe, named after grave sites in southern Germany, which flourished from around 1200 BC. This theory links the Celts with the Iron Age Hallstatt culture which followed it (c. 1200–500 BC), named for the rich grave finds in Hallstatt, Austria, and with the following La Tène culture (c. 450 BC onward), named after the La Tène site in Switzerland. It proposes that Celtic culture spread westward and southward from these areas by diffusion or migration. A newer theory, "Celtic from the West", suggests proto-Celtic arose earlier, was a lingua franca in the Atlantic Bronze Age coastal zone, and spread eastward. Another newer theory, "Celtic from the Centre", suggests proto-Celtic arose between these two zones, in Bronze Age Gaul, then spread in various directions. After the Celtic settlement of Southeast Europe in the 3rd century BC, Celtic culture reached as far east as central Anatolia, Turkey.

In Europe, the Iron Age is the last stage of the prehistoric period and the first of the protohistoric periods, which initially meant descriptions of a particular area by Greek and Roman writers. For much of Europe, the period came to an abrupt end after conquest by the Romans, though ironworking remained the dominant technology until recent times. Elsewhere, the period lasted until the early centuries AD, and either Christianization or a new conquest in the Migration Period.Iron working was introduced to Europe in the late 11th century BC, probably from the Caucasus, and slowly spread northwards and westwards over the succeeding 500 years. For example, the Iron Age of Prehistoric Ireland begins around 500 BC, when the Greek Iron Age had already ended, and finishes around 400 AD. The use of iron and iron-working technology became widespread concurrently in Europe and Asia.

The start of the Iron Age is marked by new cultural groupings, or at least terms for them, with the Late Bronze Age Mycenaean Greece collapsing in some confusion, while in Central Europe the Urnfield culture had already given way to the Hallstatt culture. In north Italy the Villanovan culture is regarded as the start of Etruscan civilization. Like its successor La Tène culture, Hallstatt is regarded as Celtic. Further to the east and north, and in Iberia and the Balkans, there are a number of local terms for the early Iron Age culture. Roman Iron Age is a term used in the archaeology of Northern Europe (but not Britain) for the period when the unconquered peoples of the area lived under the influence of the Roman Empire.

Gallic groups, originating from the various La Tène chiefdoms, began a southeastern movement into the Balkans from the 4th century BC. Although Gallic settlements were concentrated in the western half of the Carpathian basin, there were notable incursions and settlements within the Balkans.

From their new bases in northern Illyria and Pannonia, the Gallic invasions climaxed in the early 3rd century BC, with the invasion of Greece. The 279 BC invasion of Greece proper was preceded by a series of other military campaigns waged in the southern Balkans and against the Kingdom of Macedonia, favoured by the state of confusion ensuing from the disputed succession after Alexander the Great's death. A part of the invading Celts crossed over to Anatolia and eventually settled in the area that came to be named after them, Galatia.

The Hallstatt culture was the predominant Western and Central European archaeological culture of the Late Bronze Age (Hallstatt A, Hallstatt B) from the 12th to 8th centuries BC and Early Iron Age Europe (Hallstatt C, Hallstatt D) from the 8th to 6th centuries BC, developing out of the Urnfield culture of the 12th century BC (Late Bronze Age) and followed in much of its area by the La Tène culture. It is commonly associated with Proto-Celtic speaking populations.

It is named for its type site, Hallstatt, a lakeside village in the Austrian Salzkammergut southeast of Salzburg, where there was a rich salt mine, and some 1,300 burials are known, many with fine artifacts. Material from Hallstatt has been classified into four periods, designated "Hallstatt A" to "D". Hallstatt A and B are regarded as Late Bronze Age and the terms used for wider areas, such as "Hallstatt culture", or "period", "style" and so on, relate to the Iron Age Hallstatt C and D.

The various names used since classical times for the people known today as the Celts are of disparate origins.

The names Κελτοί (Keltoí) and Celtae are used in Greek and Latin, respectively, to denote a people of the La Tène horizon in the region of the upper Rhine and Danube during the 6th to 1st centuries BC in Graeco-Roman ethnography. The etymology of this name and that of the Gauls Γαλάται Galátai / Galli is uncertain.

The Gauls (Latin: Galli; Ancient Greek: Γαλάται, Galátai) were a group of Celtic peoples of mainland Europe in the Iron Age and the Roman period (roughly 5th century BC to 5th century AD). Their homeland was known as Gaul (Gallia). They spoke Gaulish, a continental Celtic language.

The Gauls emerged around the 5th century BC as bearers of La Tène culture north and west of the Alps. By the 4th century BC, they were spread over much of what is now France, Belgium, Switzerland, Southern Germany, Austria, and the Czech Republic, by virtue of controlling the trade routes along the river systems of the Rhône, Seine, Rhine, and Danube. They reached the peak of their power in the 3rd century BC. During the 4th and 3rd centuries BC, the Gauls expanded into Northern Italy (Cisalpine Gaul), leading to the Roman–Gallic wars, and into the Balkans, leading to war with the Greeks. These latter Gauls eventually settled in Anatolia (contemporary Turkey), becoming known as Galatians.

The Celtiberians were a group of Celts and Celticised peoples inhabiting an area in the central-northeastern Iberian Peninsula during the final centuries BC. They were explicitly mentioned as being Celts by several classic authors (e.g. Strabo). These tribes spoke the Celtiberian language and wrote it by adapting the Iberian alphabet, in the form of the Celtiberian script. The numerous inscriptions that have been discovered, some of them extensive, have enabled scholars to classify the Celtiberian language as a Celtic language, one of the Hispano-Celtic (also known as Iberian Celtic) languages that were spoken in pre-Roman and early Roman Iberia. Archaeologically, many elements link Celtiberians with Celts in Central Europe, but also show large differences with both the Hallstatt culture and La Tène culture.

There is no complete agreement on the exact definition of Celtiberians among classical authors, nor modern scholars. The Ebro river clearly divides the Celtiberian areas from non-Indo-European speaking peoples. In other directions, the demarcation is less clear. Most scholars include the Arevaci, Pellendones, Belli, Titti and Lusones as Celtiberian tribes, and occasionally the Berones, Vaccaei, Carpetani, Olcades or Lobetani.

The Boii (Latin plural, singular Boius; Ancient Greek: Βόιοι) were a Celtic tribe of the later Iron Age, attested at various times in Cisalpine Gaul (present-day Northern Italy), Pannonia (present-day Austria and Hungary), present-day Bavaria, in and around present-day Bohemia (after whom the region is named in most languages; comprising the bulk of today's Czech Republic), parts of present-day Slovakia and Poland, and Gallia Narbonensis (located in modern Languedoc and Provence).

In addition, the archaeological evidence indicates that in the 2nd century BC Celts expanded from Bohemia through the Kłodzko Valley into Silesia, now part of Poland and the Czech Republic.
