The Segusini (Gaulish: * Segusinoi, 'those of Segusio') were a Gauls tribe dwelling around present-day Susa, in the Alpes Cottiae, during the Iron Age.
Name
They are mentioned as
Segosianō̃n (Σεγοσιανῶν)
Strabo (early 1st c. AD),
[Strabo. Geōgraphiká, 4:1:11.] as
Segousianō̃n (Σεγουσιανῶν)
Ptolemy (2nd c. AD),
[Ptolemy. Geōgraphikḕ Hyphḗgēsis, 3:1:36.] as
Segusinorum on the Arch of Susa,
[CIL 5:7231.] and as
Segusinae on an inscription.
[CIL 5:7250.][, s.v. Segusini.]
The ethnonym Segusini is a latinized form of Gaulish * Segusinoi. It means 'the people of Segusio', itself from the root sego- ('victory, force').
Geography
The Segusini dwelled in the valley of the
Dora Riparia, around Segusio (modern Susa). Their territory was located east of the
Medulli and
Belaci, south of the
Acitavones, and west of the
Iemerii and
Taurini.

Their chief town, Segusio, controlled the route over Mont Genèvre and served as the gateway into the Italian Peninsula. Segusio possessed Latin law probably from the time of Augustus (27 BC–14 AD) and was a municipium from the time of Nero (54–58 AD). It was conquered by Constantinus in 312 AD.
History
They are attested on the Arch of Susa, erected by
Cottius in 9–8 BC.
