Did the Celts Always Live in Ireland? No—They Migrated There

The Celts were a broad Indo-European ethnolinguistic group originating in Central Europe (Hallstatt/La Tène cultures, ~800–450 BCE). They spread across Europe—Gaul, Iberia, Balkans, Anatolia.

Arrival in Ireland: Multiple waves from ~600 BCE onward (likely via Britain). They became the dominant culture, bringing:

• Ironworking
• La Tène art style
• Gaelic language (Q-Celtic branch)
• Tribal kingship, druidic religion

Pre-Celtic peoples (builders of Newgrange, ~3200 BCE) were absorbed. So: Celts have been in Ireland ~2,600 years—not "always," but foundational to Irish identity.
