Celtic Tribes


Seduni (Gauls / Celto-Ligurians?)

FeatureIn general terms, the Romans coined the name 'Gaul' to describe the Celtic tribes of what is now central, northern, and eastern France. The Gauls were divided from the Belgae to the north by the Marne and the Seine, and from the Aquitani to the south by the River Garonne, while also extending into Switzerland, northern Italy, and along the Danube (see feature link for a discussion of the origins of the Celtic name).

MapBy the middle of the first century BC, there existed a cluster of smaller tribes in the Alpine region of western Switzerland and the French/Italian border (see map link for all tribal locations).

This included the Seduni who were located on the modern border between Switzerland and Italy, hugging the Alpine stretches of the upper Rhône near and around Sion (Latin Sedunum), Canton Valais. They were neighboured to the north by the Helvetii, to the east by the tribes of the Raeti, to the south by the mysterious Acitavones and the Salassi, and to the west by the Veragri and Nantuates.

The Seduni tribal name is a little bizarre when broken down, although the process is very straightforward. Taking off the plural ending leaves a core word, 'sed-', meaning 'sit'. Does that mean that the tribe were 'the seated'? Could it be extrapolated further to mean 'settled' or 'permanent' in that they were not going anywhere?

The tribe's territory was on the western edge of the very birthplace of the Celtic people (although admittedly with the Alps in-between), so they may have been in the same place from the days of the Urnfield culture. Curiously, the tribe's name may be better suited to meaning 'settlers' in the German sense instead of 'to sit' in a Celtic or Latin sense. Was there some kind of highly unlikely Germanic or Belgic mix here?

The similarity between 'Seduni' and the Germanic 'sedna/setna', meaning 'settlers' is striking (the Sedusii had precisely the same name in a mildly different form). The nearby Raurici tribe exhibit similar potential Germanic/Belgic influences, despite there being no record of such influences in this region at this time. Could the influences instead be from the very close-by Raeti?

The tribe occupied territory in the region of modern Sion, on the upper Rhône, with an oppidum at Sedunum (Sion itself, now the capital of the Valais canton in south-western Switzerland). Along with their near neighbours they controlled one of the important passes through the Alps, and they made life extremely difficult for the Romans in the first century BC.

Sion itself has been occupied since at least 6200 BC, whilst early Neolithic farmers arrived there around 5800 BC. A population increase in the Middle Neolithic saw a sharp spread in farming activities, while the continuous stelae-production culture there seems to have come to an end around 2300 BC, no doubt enforced by Bell Beaker influences. Proto-Celtic Urnfield occupation would have come in the second millennium BC.

56 BC

Following his successful campaign against the Belgae in the previous year, Caesar heads for Italy. He sends Servius Galba ahead with the Twelfth Legion and part of the cavalry to secure the way.

The pass through the Alps has been dominated by the Nantuates, Seduni, and Veragri tribes, making the route a dangerous one for Roman merchants, and now is the time to end that danger.

Map of Alpine and Ligurian tribes, c.200-15 BC
The origins of the Euganei, Ligurians, Raeti, Veneti, and Vindelici are confused and unclear, but in the last half of the first millennium BC they were gradually being Celticised or were combining multiple influences to create hybrid tribes (click or tap on map to view full sized)

Galba conducts a few successful battles and storms several of their forts, until the tribes send embassies and hostages, and peace is concluded. Galba stations two cohorts among the Nantuates, and sets up camp with the legion's remaining cohorts in the village of Octodurus, which belongs to the Veragri.

The village is situated in a valley with a small plain, and is bounded on all sides by very high mountains. Galba takes the unoccupied half of the village as winter quarters for his troops, and fortifies it with a rampart and ditch.

Several days later, the Veragri tribe has vanished from the village and has assembled in the mountains overlooking the valley with a very large force of Nantuates and Seduni. The legion, which is reduced in size after detachments have been made, appears vulnerable to the Celts, who are convinced that the Romans want to conquer all of Gaul.

Great St Bernard's Pass
The region around the Great St Bernard's Pass was a perfect mix of fertile plains and protective high mountains for small but aggressive Celtic tribes in the four centuries or so between their settlement of the area and domination by Rome

The Romans decide to defend their position, and are hard-pressed by the superior numbers attacking them, perhaps thirty thousand in all. The six hour battle ends when the exhausted Romans make a last-ditch sally which takes the Celts by surprise and inflicts heavy casualties on them, forcing them to withdraw.

Having survived the onslaught the Romans withdraw in good order, heading westwards into the territory of the Allobroges where they settle into safer winter quarters.

25 - 15 BC

Augustus determines that the Alpine tribes need to be pacified in order to end their warlike behaviour, alternately attacking or extracting money from Romans who pass through the region, even when they have armies in tow.

He wages a steady, determined campaign against them during the Alpine Wars, and in a period of ten years he 'pacifies the Alps all the way from the Adriatic to the Tyrrhenian seas' (written by Augustus himself).

La Turbie and the Trophy of Augustus

14 BC

Emperor Augustus creates the province of Alpes Maritimae (the maritime, or seaward, Alps). It has its capital at Cemenelum (modern Nice, although this is switched in 297 to Civitas Ebrodunensium, modern Embrun). The history of the Alpine region's population of Celts and Celto-Ligurians is now tied to that of the empire.
