The Tigurini were a clan or tribe forming one out of four pagi (provinces) of the Helvetii.[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. Their name has a meaning of "lords, rulers" (cognate with Irish tigern "lord"). The other Helvetian tribes included the Verbigeni and the Tougeni (sometimes identified with the Teutones), besides one tribe that has remained unnamed.
