Helvetii - Authority in Tribe from ~300 BC to 69 AD
The Helvetii were a Gallic tribe or tribal confederation occupying most of the Swiss plateau at the time of their contact with the Roman Republic in the 1st century BC.

In 58 BC, they attempted to migrate to southern Gaul - an event serving as a catalyst for Caesar's conquest of Gaul. According to Caesar, the territory abandoned by the Helvetii had comprised 400 villages and 12 oppida (fortified settlements).

The Helvetii struck coins in gold, silver and base metal. The gold staters typically imitate the staters of Philip II of Macedon, wheras the base metal coins are of an original Celtic design.
