Commentarii de Bello Gallico (Classical Latin: [kɔm.mɛnˈtaː.ɾi.iː deː ˈbɛl.loː ˈɡal.lɪ.koː]; English: Commentaries on the Gallic War), also called Bellum Gallicum (English: Gallic War), is a book written by Julius Caesar that describes his experiences during the Gallic Wars. The work is written in the third person and details the battles and political actions that occurred during the nine years Caesar spent fighting Celtic and Germanic peoples in Gaul, who resisted Roman rule.
The term "Gaul" that Caesar used is unclear, as it had different meanings in Roman writing during his time. Generally, "Gaul" referred to areas mainly inhabited by Celts, excluding the region of Gallia Narbonensis (modern-day Provence and Languedoc-Roussillon), which had already been conquered by the Romans. This meant "Gaul" included much of modern France, Belgium, western Germany, and parts of Switzerland. As the Roman Republic expanded into Celtic lands, the definition of "Gaul" changed over time. The word was also used in common speech to describe people or places as "uncivilized" or "unsophisticated," as Romans often viewed Celts as less advanced than themselves.
Commentarii de Bello Gallico has been widely used in Latin education because of its clear and straightforward writing style. The book begins with the famous sentence Gallia est omnis divisa in partes tres, meaning "Gaul is divided into three parts." The full work is divided into eight books, numbered Book 1 to Book 8, with each book containing between about 5,000 and 15,000 words. Book 8 was written by Aulus Hirtius after Caesar’s death.
Although many people at the time and later historians believed the account was accurate, 20th-century historians have questioned some claims in the work. For example, Caesar wrote that the Romans fought against Gallic forces as large as 430,000 soldiers, a number many historians believe was impossible for an army at that time. He also claimed that no Roman soldiers died in these battles, a detail that has also been widely debated.
Title
The Latin title, Commentaries on the Gallic War, is often kept in English translations of the book. The title is also translated as About the Gallic War, Of the Gallic War, On the Gallic War, The Conquest of Gaul, and The Gallic War.
Motivations
Caesar's successes in Gaul made his enemies in Rome more worried and angry. His powerful opponents, the optimates, spread stories about what Caesar might do once he returned from Gaul. The optimates planned to accuse Caesar of misusing his power when he gave up his authority. If this happened, Caesar could lose his wealth, citizenship, and the laws he passed during his time as consul and pro-consul of Gaul.
To protect himself from these threats, Caesar needed the support of the plebeians, especially the Tribunes of the Plebs, who helped him achieve his goals. The Commentaries were writings Caesar created to speak directly to the plebeians, avoiding the usual way of communicating through the Senate. He used these writings to share his actions as efforts to bring glory and strength to Rome. By gaining the people's support, Caesar aimed to avoid being challenged by the wealthy and powerful. He argued that the Gallic Wars were fair and honorable, and that he and his army fought Gaul to defend Rome. By showing himself as a strong and skilled military leader, Caesar removed any doubts in Rome about his leadership abilities.
Synopsis
The Commentaries describe the Gallic Wars, which lasted eight years. The wars began in 58 BC when the Helvetians started moving through the provinces. When nearby allies asked Caesar for help against the Helvetians, he used this as a reason to gather his army. This action brought other tribes, including the Germanic Suebi, into the conflict.
By 57 BC, Caesar decided to conquer all of Gaul. He led battles in the east, where the Nervii almost defeated him. In 56 BC, Caesar defeated the Veneti in a naval battle and took control of most of northwest Gaul. In 55 BC, Caesar wanted to improve his reputation, so he led expeditions across the Rhine River and the English Channel. These were the first such journeys by Romans. After returning from Britain, Caesar was celebrated as a hero, but he had not achieved much because his army was too small and he could not bring his cavalry. The next year, he returned with a larger army, including cavalry, and was more successful. He helped set up a friendly king and made peace with a rival. However, tribes on the continent rebelled, and the Romans suffered a major defeat.
In 53 BC, Caesar launched a harsh campaign to control the Gauls, but it failed. In 52 BC, the Gauls rebelled under the leadership of Vercingetorix. Gallic forces won a key battle at Gergovia, but the Romans defeated the Gallic coalition at the Battle of Alesia through strong siege tactics.
In 51 BC and 50 BC, there was little resistance, and Caesar’s troops focused on securing the region. Gaul was conquered, but it did not become a Roman province until 27 BC. Resistance continued until as late as 70 AD. The war had no clear end date, but the upcoming Roman Civil War caused Caesar’s troops to leave Gaul in 50 BC. Caesar’s victories in the Gallic Wars made him very wealthy and gave him great fame. These successes helped him win the Civil War and become dictator, leading to the end of the Roman Republic and the creation of the Roman Empire.
Motifs and peoples in theDe Bello Gallico
In the Commentarii de Bello Gallico, Caesar writes about several leaders of the Gallic tribes. Two important figures are Diviciacus and Vercingetorix, who played key roles in the Gallic wars.
Books 1 and 6 describe Diviciacus, a leader of the Haedui (Aedui). Caesar trusted Diviciacus deeply, calling him "the one person in whom Caesar had absolute confidence" (1.41). Diviciacus’s brother, Dumnorix, had acted against the Romans to become king (1.18). Caesar avoided punishing Dumnorix and instead forced Diviciacus to control his brother. Diviciacus begged Caesar to spare his brother’s life, and Caesar used this moment to strengthen his alliance with the Haedui. Diviciacus also asked Caesar to attack the Germans and their leader, Ariovistus. Caesar agreed, partly because the Gallic people feared Ariovistus and wanted action.
Vercingetorix, leader of the Arverni, united the Gallic tribes against Caesar during the winter of 53–52 BC, as described in Book VII, chapters 1–13. His father, Celtillus, had been killed trying to take power, which made Vercingetorix an outcast. After Caesar defeated the rebellion, Vercingetorix offered to surrender to save his people. He was later taken to Rome, imprisoned for six years, and then executed during Caesar’s triumph over Gaul. Today, Vercingetorix is seen as a hero in France and a symbol of resistance to Roman rule.
In De Bello Gallico 6.21–28, Caesar describes the lifestyle and culture of the Germanic people. He writes that they lived as hunter-gatherers, eating mostly meat and dairy. They worshipped gods like the sun, fire, and moon. German women wore cloaks made of deer hides and bathed in rivers with men, but men who avoided sex were admired. Caesar also mentions the Hercynian forest, where he claims there are unusual animals like oxen with horns on their foreheads and elk without joints.
Caesar notes that the Germans are known for their love of war, which they see as a sign of bravery. They have no neighbors because they have driven others away. Their leaders, called wartime magistrates, have power over life and death. Caesar respects their warrior spirit but criticizes their customs as too harsh compared to the educated Gallic Druids. For example, he writes that stealing outside the state is allowed to teach discipline, a practice that would seem strange to Romans. Caesar’s descriptions, along with those of Tacitus, helped shape the ancient world’s view of the Germans as "barbaric."
Caesar’s accounts of the Druids and Gallic beliefs appear in De Bello Gallico 6.13, 14, and 16–18. In chapter 13, he explains the Druids’ important role in Gallic society. Chapter 14 describes their education and high social status. In chapter 16, Caesar writes about their sacrificial practices, including burning people alive to stop famine or war. Chapters 17 and 18 mention the gods the Gauls worshipped, including Dis, whom they claimed to be their ancestor.
Although Caesar spent much time in Gaul, much of his knowledge about the Druids came from others, not his own experience. He used information from writers like Posidonius. Caesar wrote about the Druids to inform Romans about the people they conquered.
Scholars agree the Druids made sacrifices to their gods, but they are unsure what kind of offerings they used. Caesar and other Roman writers claim the Druids sometimes sacrificed humans to ease disease, famine, or to win wars. In chapter 16, Caesar describes a ritual where people were burned alive inside large wooden statues.
Caesar also notes that the Druids had a civil structure. In chapter 13, he writes that they chose a single leader, who ruled until death, and a new leader was selected by vote or through conflict. The Druids studied the stars, the cosmos, and the powers of gods, showing they understood astrology, cosmology, and theology. Some believe Caesar portrayed the Druids as both barbaric (because of human sacrifices) and civilized (because of their knowledge), to show they could be assimilated into Roman society.
In De Bello Gallico 5.44, Caesar mentions two centurions, Lucius Vorenus and Titus Pullo, who served under Quintus Tullius Cicero, brother of Marcus Tullius Cicero. They were rivals who competed fiercely for honors. During a siege by the Belgae, led by Ambiorix, they jumped over the wall into the enemy despite being outnumbered. They saved each other during the battle, first Vorenus saving Pullo, then Pullo saving Vorenus. Both survived, killing many enemies. They returned to camp with praise and honors, proving their bravery and equality.
Caesar uses this story to show the courage and bravery of his soldiers.
Modern influence
This book is often praised for its clear and well-written Latin. A German historian named Hans Herzfeld says it is an example of clear writing and good reporting. It is often the first real text taught to Latin students, just as Xenophon's Anabasis is for students of Ancient Greek. Both are stories about military adventures written from a third-person perspective. The text includes many details and uses writing techniques to support Caesar's political goals.
The books are valuable because they include many geographical and historical details. Important sections describe Gaulish customs (6.13), their religion (6.17), and a comparison between Gauls and Germanic peoples (6.24).
Manuscripts and publication history
Since Karl Nipperdey’s work in 1847, existing manuscripts of De Bello Gallico have been grouped into two classes. The first class (α) includes manuscripts that contain only De Bello Gallico and have notes at the end that reference late antique correctors. The oldest manuscript in this group is MS. Amsterdam 73, which was written at Fleury Abbey in the later ninth century. The second class (β) includes manuscripts that contain all related works: De Bello Gallico, De Bello Civili, De Bello Alexandrino, De Bello Africo, and De Bello Hispaniensi, always in that order. The oldest manuscript in this group is MS Paris lat. 3864, which was written at Corbie in the last quarter of the ninth century. For De Bello Gallico, the text in class α is considered more accurate than class β. In total, about 240 medieval manuscripts preserve the text, and beyond the two groupings mentioned, the stemma codicum (the family tree of manuscripts) is not fully understood.
The first printed edition of De Bello Gallico was published by Giovanni Andrea Bussi in Rome in 1469.
The original publication date of De Bello Gallico is uncertain. It was definitely published by 46 BC, as Cicero reviewed it and praised it highly. It is unclear whether the books were released individually or all at once. Nipperdey’s 1847 study suggested they were mostly written together in 50 BC. Frank Adcock proposed in 1956 that they were written over time but released together. T. P. Wiseman believed they were written and published yearly, as this would have helped Caesar keep the public informed about his military actions. The debate about when and how the work was published continues, with scholars analyzing changes in writing style to determine its date. Even if the books were published after the wars, it was clear that Caesar used writing as part of a propaganda campaign during the war, including sending many letters to political allies in Rome. Because the war was controversial and Caesar faced threats from enemies who wanted to accuse him of war crimes, winning public support was essential for him.
Historiography
Caesar's account of his Gallic Wars was widely believed to be true and accurate until the 1900s. In 1847, Nipperdey's manuscript was called "monumental" and was the first detailed analysis of Caesar's text. At that time, many believed Caesar was always correct. Nipperdey even changed parts of his translation when they seemed to contradict each other, assuming Caesar was right in those cases. In 1908, Camille Jullian wrote a full history of Gaul and accepted Caesar's account as completely accurate. However, after World War II, historians began to question whether Caesar's claims were reliable.
Historian David Henige focuses on Caesar's reported numbers about the Helvetii people. Caesar claimed he estimated their population by finding a Greek-written census on tablets in their camp. He said there were 263,000 Helvetii and 105,000 allies, with 92,000 of them being warriors. Henige argues that such a census would have been difficult for the Gauls to create, especially since it was written in Greek by non-Greek tribes. He also notes that carrying so many tablets during a migration would have been a huge challenge. Henige believes the exact number of warriors being one-quarter of the total suggests Caesar may have made up the numbers rather than counting them. Other ancient writers, like Livy, gave lower estimates for the Helvetii and their allies, but Henige also thinks those numbers might not be accurate.
During the campaign against the Usipetes and Tenceri, Caesar claimed the Romans faced an army of 430,000 Gauls, won completely, and suffered no losses. He also said the defeated Gauls committed mass suicide. Henige and historian Ferdinand Lot, writing in 1947, both found this story impossible. Lot was one of the first modern scholars to question the accuracy of Caesar's numbers, calling a force of 430,000 unlikely for that time.
Not all people who lived during Caesar's time believed his account was accurate. Gaius Asinius Pollio, who fought with Caesar, noted that the text seemed carelessly written and not always truthful. However, Pollio thought the errors were made by Caesar's officers or that Caesar intended to correct the text later. Until the 1900s, most authors agreed with Pollio, blaming mistakes on translation or copying errors over time. In 1876, Ernest Desjardins suggested that a mistake in writing numbers—such as "CCCCXXX" instead of "XXXXIII"—might have caused Caesar to report 430,000 instead of 43,000. Henige acknowledges that early manuscripts of Caesar's work date back only to the 9th to 12th centuries, which may have led to inaccuracies.
Modern historians use Caesar's work, the Commentarii de Bello Gallico, to estimate the population of Gaul before Rome. In the 1700s, some guessed 40–200 million people. In the 1800s, estimates dropped to 15–20 million. By the 1900s, some believed as few as 4 million, while Henige suggests a range of 4–48 million.
Henige views Caesar's work as a form of propaganda designed to make Caesar look more powerful than he was. He notes that Caesar's straightforward writing style made it easier for readers to accept his exaggerated claims. Caesar portrayed his actions as a defense against the "barbarity" of the Gauls, even though he was the aggressor. By describing his victories as overwhelming and his losses as minimal, Caesar made it seem as though the Romans were destined to win against the "godless" Gauls. Henige concludes that Caesar was one of history's earliest and most successful "spin doctors."
Although Caesar used his account to promote his image, the De Bello Gallico is not entirely unreliable. The major victories Caesar described did happen. However, smaller details may have been changed, and his word choices made readers more sympathetic to his cause. The work is often studied as a commentary rather than a strict historical record because it shows how events can be rewritten to benefit a person.
