Indo-European in the context of "Sicels"

A language family is a group of languages related through descent from a common ancestor, called the proto-language of that family. The term family is a metaphor borrowed from biology, with the tree model used in historical linguistics analogous to a family tree, or to phylogenetic trees of taxa used in evolutionary taxonomy. Linguists thus describe the daughter languages within a language family as being genetically related. The divergence of a proto-language into daughter languages typically occurs through geographical separation, with different regional dialects of the proto-language undergoing different language changes and thus becoming distinct languages over time.

One well-known example of a language family is the Romance languages, including Spanish, French, Italian, Portuguese, Romanian, Catalan, Romansh, and many others, all of which are descended from Vulgar Latin. The Romance family itself is part of the larger Indo-European family, which includes many other languages native to Europe and South Asia, all believed to have descended from a common ancestor known as Proto-Indo-European.

The Iapygians or Apulians (Latin: Iapyges, Iapygii) were an Indo-European-speaking people, dwelling in an eponymous region of the southeastern Italian Peninsula named Iapygia (modern Apulia) between the beginning of the first millennium BC and the first century BC. They were divided into three tribal groups: the Daunians, Peucetians and Messapians. They spoke Messapic, a language of Paleo-Balkan provenance.

After their lands were gradually colonized by the Romans from the late 4th century onward and eventually annexed to the Roman Republic by the early 1st century BC, Iapygians were fully Latinized and assimilated into Roman culture.

The Yamnaya (/ˈjæmnaɪə/ YAM-ny-ə) or Yamna culture (/ˈjæmnə/ YAM-nə), also known as the Pit Grave culture or Ochre Grave culture, is a late Copper Age to early Bronze Age archaeological culture of the region between the Southern Bug, Dniester, and Ural rivers (the Pontic–Caspian steppe), dating to 3300–2600 BC. It was discovered by Vasily Gorodtsov following his archaeological excavations near the Donets River in 1901–1903. Its name derives from its characteristic burial tradition: yámnaya (я́мная) is a Russian adjective that means 'related to pits' (я́ма, yáma), as these people buried their dead in tumuli (kurgans) containing simple pit chambers. Research in recent years has found that Mykhailivka, on the lower Dnieper River, Ukraine, formed the core Yamnaya culture (c. 3600–3400 BC).

The Yamnaya culture is of particular interest to archaeologists and linguists, as the widely accepted Kurgan hypothesis posits that the people who produced the Yamnaya culture spoke a stage of the Proto-Indo-European language. The speakers of the Proto-Indo-European (PIE) language embarked on the Indo-European migrations that gave rise to the widely dispersed Indo-European languages of today.

The Neolithic period in the British Isles lasted from c. 4100 to c. 2,500 BC. Constituting the final stage of the Stone Age in the region, it was preceded by the Mesolithic and followed by the Bronze Age.

During the Mesolithic period, the inhabitants of the British Isles had been hunter-gatherers. Around 4000 BC, migrants began arriving from Central Europe. These migrants brought new ideas, leading to a radical transformation of society and landscape that has been called the Neolithic Revolution. The Neolithic period in the British Isles was characterised by the adoption of agriculture and sedentary living. To make room for the new farmland, the early agricultural communities undertook mass deforestation across the islands, which dramatically and permanently transformed the landscape. At the same time, new types of stone tools requiring more skill began to be produced, and new technologies included polishing. Although the earliest indisputably-acknowledged languages spoken in the British Isles belonged to the Celtic branch of the Indo-European family, it is not known what language the early farming people spoke.

The Pentri were a tribe of the Samnites, and apparently one of the most important of the subdivisions of that nation. According to Salmon, their name shares the same Indo-European root found in the Celtic pen- <peak>. Their capital city was Bovianum Undecumanorum (Livy ix. 31), modern Bojano, in the very heart of the Samnite territory, and it is therefore probable that they occupied the whole of that rugged and mountainous district which extends from the frontiers of Latium, in the valley of the Liris (modern Liri), to those of the Frentani, towards the Adriatic Sea. But it is impossible to determine their exact limits, or to separate their history from that of the remaining Samnites. It is probable, indeed, that, throughout the long wars of the Romans with the Samnites, the Pentri were the leading tribe of the latter people, and always took part in the war, whether specified or not. The only occasion when we hear of their separating themselves from the rest of their countrymen, is during the Second Punic War, when we are told that all the other Samnites, except the Pentri, declared in favour of Hannibal after the battle of Cannae, 216 BC. (Liv. xxii. 61.) This is the last occasion on which we find their name in history; all trace of the distinction between them and the other Samnites seems to have been subsequently lost, and their name is not even mentioned by Strabo or Pliny.

The Dacians (/ˈdeɪʃənz/; Latin: Daci [ˈdaːkiː]; Ancient Greek: Δάκοι, Δάοι, Δάκαι) were the ancient Indo-European inhabitants of the cultural region of Dacia, located in the area near the Carpathian Mountains and west of the Black Sea. They are often considered a subgroup of the Thracians. This area includes mainly the present-day countries of Romania and Moldova, as well as parts of Ukraine, Eastern Serbia, Northern Bulgaria, Slovakia, Hungary and Southern Poland. The Dacians and the related Getae spoke the Dacian language, which has a debated relationship with the neighbouring Thracian language and may be a subgroup of it. Dacians were somewhat culturally influenced by the neighbouring Scythians and by the Celtic invaders of the 4th century BC.

Turanism, also known as Turanianism, pan-Turanism or pan-Turanianism, is a pan-nationalist political movement built around pseudoscientific claims of biological and linguistic connections between various ethnic groups of Eurasia. It revolves around the abandoned proposal of a Ural-Altaic language family, which hypothesizes that the Turkic, Mongolic, Tungusic, and Uralic peoples share Inner and Central Asian origins and therefore close cultural, ethnic, and linguistic bonds. Supporters of Turanism propose political unity among these groups, chiefly to oppose the cultural and political influences of the Indo-Europeans of Europe, West Asia, and South Asia, as well as the Sino-Tibetans of East Asia. The movement emerged in the 19th century to counter pan-nationalist ideologies such as pan-Germanism, and built upon the ideas of pan-Slavism (e.g. the idea of a "Turanian brotherhood and collaboration" was borrowed from the pan-Slavic concept of "Slavic brotherhood and collaboration").
