Tigurini

[1][2] The Tigurini were the most important group of the Helvetii, mentioned by both Julius Caesar and Poseidonius, settling in the area of what is now the Swiss canton of Vaud, corresponding to the bearers of the late La Tène culture in western Switzerland.

After the end of the war, they returned to their earlier homes, settling in the western Swiss plateau and the Jura mountains north of Lake Leman.

[6] The names of the Tigurini and the Helvetii had retained a connotation of a "barbarian" threat from the north for the Romans, employed by Julius Caesar as a motivation for his expedition to Gaul by suggesting that these tribes were "on the move again".

In 58 BCE the Helvetii encountered the armies of Caesar, and were defeated and massacred in the battles of the Arar and the Bibracte, allegedly leaving 228,000 dead.

As a means of asserting control over the military access routes to Gaul, the Romans established the Colonia Iulia Equestris at the site of the Helvetian settlement of Noviodunum (Nyon).

The Tigurini were a pagus of the Helvetii .
