Helvetii in the context of "Barbarian"

The Gallic Wars were waged between 58 and 50 BC by the Roman general Julius Caesar against the peoples of Gaul (present-day France, Belgium, and Switzerland). Gallic, Germanic, and Brittonic tribes fought to defend their homelands against an aggressive Roman campaign. The Wars culminated in the decisive Battle of Alesia in 52 BC, in which a complete Roman victory resulted in the expansion of the Roman Republic over the whole of Gaul. Though the collective Gallic armies were as strong as the Roman forces, the Gallic tribes' internal divisions eased victory for Caesar. Gallic chieftain Vercingetorix's attempt to unite the Gauls under a single banner came too late. Caesar portrayed the invasion as being a preemptive and defensive action, but historians agree that he fought the wars primarily to boost his political career and to pay off his debts. Still, Gaul was of significant military importance to the Romans. Native tribes in the region, both Gallic and Germanic, had attacked Rome several times. Conquering Gaul allowed Rome to secure the natural border of the river Rhine.

The wars began with conflict over the migration of the Helvetii in 58 BC, which drew in neighboring tribes and the Germanic Suebi. By 57 BC, Caesar had resolved to conquer all of Gaul. He led campaigns in the east, where the Nervii almost defeated him. In 56 BC, Caesar defeated the Veneti in a naval battle and took most of northwest Gaul. In 55 BC, Caesar sought to boost his public image. He undertook first-of-their-kind expeditions across the Rhine and the English Channel. Rome hailed Caesar as a hero upon his return from Britain, though he had achieved little beyond landing because his army had been too small. The next year, he returned with a larger army and reached much further inland; he extracted tribute from the locals and returned to Gaul. Tribes rose up on the continent, and the Romans suffered a humiliating defeat. 53 BC saw a brutal pacification campaign. That failed, and Vercingetorix led a revolt in 52 BC. Gallic forces won a notable victory at the Battle of Gergovia, but the Romans' indomitable siege works at the Battle of Alesia crushed the Gallic coalition.

Raetia or Rhaetia (/ˈriːʃ(i)ə/ REE-sh(ee-)ə, Latin: [ˈrae̯.ti.a]) was a province of the Roman Empire named after the Rhaetian people. It bordered on the west with the country of the Helvetii, on the east with Noricum, on the north with Vindelicia, on the south-west with Transalpine Gaul and on the south with Venetia et Histria, a region of Roman Italy.

It thus comprised the districts occupied in modern times by eastern and central Switzerland (containing the Upper Rhine and Lake Constance), southern Germany (Bavaria and most of Baden-Württemberg), Vorarlberg and the greater part of Tyrol in Austria, and part of northern Lombardy in Italy. The region of Vindelicia (today eastern Württemberg and western Bavaria) was annexed to the province at a later date than the others. The northern border of Raetia during the reigns of emperors Augustus and Tiberius was the River Danube. Later the Limes Germanicus marked the northern boundary, stretching for 166 km north of the Danube. Raetia was connected to Italy across the Alps over the Reschen Pass, by the Via Claudia Augusta.

The Tigurini were a clan or tribe forming one out of four pagi (provinces) of the Helvetii.

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.
