Gaul (Celtic)

Gaul was never a single state but a sprawling collection of Celtic tribes — the Aedui, Arverni, Helvetii, and dozens more — spread across what is now France, Belgium, and beyond. Skilled metalworkers and fierce warriors, they had once terrorized the Mediterranean world, sacking Rome and raiding into Greece. Their independence ended with Julius Caesar’s brutal campaigns from 58 BCE. The decisive blow fell in 52 BCE at Alesia, where Caesar besieged and captured the charismatic chieftain Vercingetorix, who had briefly united the tribes. Gaul became a Roman province, and within generations its elite spoke Latin and lived as Romans.
