Proto-Indo-Europeans

The Proto-Indo-Europeans were the speakers of the Proto-Indo-European language (PIE), a reconstructed prehistoric language of Eurasia.

Knowledge of them comes chiefly from the linguistic reconstruction, along with material evidence from archaeology and archaeogenetics. According to some archaeologists, PIE speakers cannot be assumed to have been a single, identifiable people or tribe, but were a group of loosely related populations ancestral to the later, still partially prehistoric, Bronze Age Indo-Europeans. This view is held especially by those archaeologists who believed it to be an original homeland of vast extent and immense time depth. However, this view is not shared by linguists, as proto-languages, like all languages before modern transport and communication, occupied small geographical areas over a limited time span, and were spoken by a set of close-knit communities—a tribe in the broad sense.

The Proto-Indo-Europeans likely lived during the late Neolithic, or roughly the 4th millennium BC. Mainstream scholarship places them in the forest-steppe zone immediately to the north of the western end of the Pontic-Caspian steppe in Eastern Europe. Some archaeologists would extend the time depth of PIE to the middle Neolithic (5500 to 4500 BCE) or even the early Neolithic (7500 to 5500 BC), and suggest alternative location hypotheses.
