The Helvetii, anglicized as Helvetians, were a Celtic tribe or tribal confederation occupying most of the Swiss plateau at the time of their contact with the Roman Republic in the 1st century BC. According to Julius Caesar, the Helvetians were divided into four subgroups or pagi. Of these, Caesar names only the Verbigeni and the Tigurini, while Posidonius mentions the Tigurini and the Tougeni (Τωυγενοί). They feature prominently in the Commentaries on the Gallic War, with their failed migration attempt to southwestern Gaul serving as a catalyst for Caesar's conquest of Gaul.

Gaul was a region of Western Europe first clearly described by the Romans, encompassing present-day France, Belgium, Luxembourg, and parts of Switzerland, the Netherlands, Germany, and Northern Italy. It covered an area of 494,000 km2 (191,000 sq mi). According to Julius Caesar, who took control of the region on behalf of the Roman Republic, Gaul was divided into three parts: Gallia Celtica, Belgica, and Aquitania.
Commentarii de Bello Gallico, also Bellum Gallicum, is Julius Caesar's firsthand account of the Gallic Wars, written as a third-person narrative. In it Caesar describes the battles and intrigues that took place in the nine years he spent fighting the Celtic and Germanic peoples in Gaul that opposed Roman conquest.
The Gallic Wars were waged between 58 and 50 BC by the Roman general Julius Caesar against the peoples of Gaul. 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.
Legio X Equestris, a Roman legion, was levied by Julius Caesar in 61 BC when he was the Governor of Hispania Ulterior. The Tenth was the first legion levied personally by Caesar and was consistently his most trusted. Legio X was famous in its day and throughout history, because of its portrayal in Caesar's Commentaries and the prominent role the Tenth played in his Gallic campaigns. Its soldiers were discharged in 45 BC. Its remnants were reconstituted, fought for Mark Antony and Octavian, disbanded, and later merged into X Gemina.
The Battle of Alesia or siege of Alesia was the climactic military engagement of the Gallic Wars, fought around the Gallic oppidum of Alesia in modern France, a major centre of the Mandubii tribe. It was fought by the Roman army of Julius Caesar against a confederation of Gallic tribes united under the leadership of Vercingetorix of the Arverni. It was the last major engagement between Gauls and Romans, and is considered one of Caesar's greatest military achievements and a classic example of siege warfare and investment; the Roman army built dual lines of fortifications—an inner wall to keep the besieged Gauls in, and an outer wall to keep the Gallic relief force out. The Battle of Alesia marked the end of Gallic independence in the modern day territory of France and Belgium.
Gallia Belgica was a province of the Roman Empire located in the north-eastern part of Roman Gaul, in what is today primarily northern France, Belgium, and Luxembourg, along with parts of the Netherlands and Germany.
Orgetorix was a wealthy aristocrat among the Helvetii, a Celtic-speaking people residing in what is now Switzerland during the consulship of Julius Caesar of the Roman Republic.
The Battle of the Arar was fought between the migrating tribes of the Helvetii and six Roman legions — The Seventh, Eighth, Ninth, Tenth legions, Eleventh and Twelfth Legions — under the command of Gaius Julius Caesar in 58 BC. It was the first major battle of the Gallic Wars and ended in a tactical victory for the outnumbered Roman army.
Roman Gaul refers to Gaul under provincial rule in the Roman Empire from the 1st century BC to the 5th century AD.
The Battle of Bibracte was fought between the Helvetii and six Roman legions, under the command of Gaius Julius Caesar. It was the second major battle of the Gallic Wars.
Legio XI Claudia was a legion of the Imperial Roman army. The legion was levied by Julius Caesar for his campaign against the Nervii. XI Claudia dates back to the two legions recruited by Julius Caesar to invade Gallia in 58 BC, and it existed at least until the early 5th century, guarding lower Danube in Durostorum.
Diviciacus or Divitiacus was a druid of the Aedui tribe who lived in Gaul during the 1st century BC. He is the only druid from antiquity whose existence is attested by name. The name may mean "avenger". His date of birth is unknown, though he was an adult during the late 60s BC, and an aristocrat who took part in the clans' decision-making, as described by Julius Caesar in Caesar's The Gallic War.
De Bello Hispaniensi is a Latin work continuing Julius Caesar's commentaries, De Bello Gallico and De Bello Civili, and its sequels by two different unknown authors De Bello Alexandrino and De Bello Africo. It details Caesar's campaigns on the Iberian Peninsula, ending with the Battle of Munda.
De Bello Alexandrino is a Latin work continuing Julius Caesar's commentaries, De Bello Gallico and De Bello Civili. It details Caesar's campaigns in Alexandria and Asia.
Gaius Calpurnius Piso was a politician and general from the Roman Republic. He became praetor urbanus in 72/71 BC. After being elected consul in 67 BC, Piso opposed Pompeius' friends, the tribunes Gaius Cornelius and Aulus Gabinius. Assigned both Gallia Narbonensis and Gallia Cisalpina, he remained as proconsul until 65, or perhaps later in Cisalpina. Piso defeated an Allobrogian rebellion and repressed troubles in Transpadana, for which he was unsuccessfully prosecuted by Caesar. He supported Cicero during the Catiline conspiracy.
The military campaigns of Julius Caesar constituted both the Gallic Wars and Caesar's civil war. The Gallic War mainly took place in what is now France. In 55 and 54 BC, he invaded Britain, although he made little headway. The Gallic War ended with complete Roman victory at the Battle of Alesia. This was followed by the civil war, during which time Caesar chased his rivals to Greece, decisively defeating them there. He then went to Egypt, where he defeated the Egyptian pharaoh and put Cleopatra on the throne. He then finished off his Roman opponents in Africa and Hispania. Once his campaigns were over, he served as Roman dictator until his assassination on 15 March 44 BC. These wars were critically important in the transition of the Roman Republic into the Roman Empire.
A vergobret was a magistrate in ancient Gaul who held the highest office in many Gallic cities, especially among the Aedui. Julius Caesar discusses the role of the vergobret several times in his Commentaries on the Gallic War, referring to the office with the terms princeps civitatis, principatus, and magistratus.
