Early Italian campaigns (458–396 BC)




The first non-apocryphal Roman wars were wars of both expansion and defence, aimed at protecting Rome itself from neighbouring cities and nations and establishing its territory in the region. Florus writes that at this time

Although sources disagree, it is possible that Rome itself was twice invaded by Etruscan armies in this period, first in around 509 BC under the recently-overthrown king Tarquinius Superbus, and again in 508 BC under the Etruscan Lars Porsenna.

However, Rome still controlled only a very limited area and the affairs of Rome were minor even to those in Italy: the remains of Veii, for instance, lie entirely within modern Rome's suburbs and Rome's affairs were only just coming to the attention of the Greeks, the dominant cultural force at the time.

, to the north. The Celtic civilization at this time was vibrant and growing in strength and territory, and stretched, if incohesively, across much of mainland Europe. It is at the hands of the Gallic Celts that Rome suffered a humiliating defeat that temporarily set back its advance and was to imprint itself upon the Roman consciousness.

Celtic invasion of Italia (390–387 BC)



By 390 BC, several Gallic tribes had begun invading Italy from the north as their culture expanded throughout Europe. Most of this was unknown to the Romans at this time, who still had purely local security concerns, but the Romans were alerted when a particularly warlike tribe, the Senones

, not far from Rome's sphere of influence. The Clusians, overwhelmed by the size of the enemy in numbers and ferocity, called on Rome for help. Perhaps unintentionally the Romans found themselves not just in conflict with the Senones, but their primary target. The Romans met them in pitched battle at the Battle of the Allia

, defeated the Roman army of around 15,000 troops and proceeded to pursue the fleeing Romans back to Rome itself and partially sacked the town before being either driven off or bought off.

Expansion into Italia (343–282 BC)



After recovering surprisingly swiftly from the sack of Rome, the Romans immediately resumed their expansion within Italy. Despite their successes so far, their mastery of the whole of Italy was by no means assured at this point: the Samnites were a people just as martial and as rich as the Romans and with an objective of their own of securing more lands in the fertile Italian plains on which Rome itself lay. The First Samnite War of between 343 BC and 341 BC that followed widespread Samnite incursions into Rome's territory was a relatively short affair: the Romans beat the Samnites in both the Battle of Mount Gaurus

Rome was therefore forced to contend by around 340 BC against both Samnite incursions into their territory and, simultaneously, in a bitter war against their former allies. Rome bested the Latins in the Battle of Vesuvius

, after which the Latin cities were obliged to submit to Roman rule. Perhaps due to Rome's lenient treatment of their defeated foe, the Latins submitted largely amicably to Roman rule for the next 200 years.

The Second Samnite War, from 327 BC to 304 BC, was a much longer and more serious affair for both the Romans and Samnites, running for over twenty years and incorporating twenty-four battles that led to massive casualties on both sides. The fortunes of the two sides fluctuated throughout its course: the Samnites seized Neapolis in the Capture of Neapolis

 with progressively less generous terms. By 304 BC the Romans had effectively annexed the greater degree of the Samnite territory, founding several colonies. This pattern of meeting aggression in force and almost inadvertently gaining territory in strategic counter-attacks was to become a common feature of Roman military history.

Seven years after their defeat, with Roman dominance of the area looking assured, the Samnites rose again and defeated the Romans at the Battle of Camerinum

 against Carthage, abandoning his allies to deal with the Romans.

When his Sicilian campaign was also ultimately a failure, and at the request of his Italian allies, Pyrrhus returned to Italy to face Rome once more. In 275 BC, Pyrrhus again met the Roman army at the Battle of Beneventum. This time the Romans had devised methods to deal with the war elephants, including the use of javelins, fire and, one source claims, simply hitting the elephants heavily on the head. While Beneventum was indecisive, Pyrrhus realised that his army had been exhausted and reduced by years of foreign campaigns, and seeing little hope for further gains, he withdrew completely from Italy.

The conflicts with Pyrrhus would have a great effect on Rome, however. Rome had shown that it was capable of pitting its armies successfully against the dominant military powers of the Mediterranean, and further showed that the Greek kingdoms were incapable of defending their colonies in Italy and abroad. Rome quickly moved into southern Italia, subjugating and dividing Magna Grecia. Effectively dominating the Italian peninsula, and with a proven international military reputation, Rome now began to look outwards at expansion from the Italian mainland. Since the Alps formed a natural barrier to the north, and Rome was none too keen to meet the fierce Gauls in battle once more, the city's gaze turned to Sicily and the islands of the Mediterranean, a policy that would bring it into direct conflict with its former ally Carthage

Internal unrest (135–71 BC)


The extensive campaigning abroad by Roman generals, and the rewarding of soldiers with plunder on these campaigns, led to a general trend of soldiers becoming increasingly loyal to their generals rather than to the state, and to a willingness to follow their generals in battle against the state. Rome was also plagued by several slave uprisings during this period, in part because in the past century vast tracts of land had been given over to slave farming in which the slaves greatly outnumbered their Roman masters. In the last century BC at least twelve civil wars and rebellions occurred. This pattern did not break until Octavian (later Caesar Augustus) ended it by becoming a successful challenger to the Senate's authority, and was made princeps

Caesar's early campaigns (59–50 BC)

 of the Roman Julii clan defeated the Calaici and Lusitani in battle. Following a consular term, he was then appointed to a five year term as Proconsular Governor of Transalpine Gaul (current southern France) and Illyria (the coast of Dalmatia). Not content with an idle governorship, Caesar strove to find reason to invade Gaul, which would give him the dramatic military success he sought. To this end he stirred up popular nightmares of the first sack of Rome by the Gauls and the more recent spectre of the Cimbri and Teutones. When the Helvetii

Commentarii de Bello Gallico
Commentarii de Bello Gallico 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 local armies in Gaul that opposed Roman domination...

("Commentaries on the Gallic War").

Gaul never regained its Celtic identity, never attempted another nationalist rebellion, and remained loyal to Rome until the fall of the Western Empire in 476. However, although Gaul itself was to thereafter remain loyal, cracks were appearing in the political unity of Rome's governing figures – partly over concerns over the loyalty of Caesar's Gallic troops to his person rather than the state – that were soon to drive Rome into a lengthy series of civil wars.

Triumvirates, Caesarian ascension, and revolt (53–30 BC)


By 59 BC an unofficial political alliance known as the First Triumvirate
First Triumvirate
The First Triumvirate was the political alliance of Gaius Julius Caesar, Marcus Licinius Crassus, and Gnaeus Pompeius Magnus. Unlike the Second Triumvirate, the First Triumvirate had no official status whatsoever – its overwhelming power in the Roman Republic was strictly unofficial...

 in "the greatest Roman defeat since Hannibal" in which Crassus himself perished. The death of Crassus removed some of the balance in the Triumvirate and, consequently, Caesar and Pompey began to move apart. While Caesar was fighting against Vercingetorix in Gaul, Pompey proceeded with a legislative agenda for Rome that revealed that he was at best ambivalent towards Caesar and perhaps now covertly allied with Caesar's political enemies. In 51 BC, some Roman senators demanded that Caesar would not be permitted to stand for Consul unless he turned over control of his armies to the state, and the same demands were made of Pompey by other factions. Relinquishing his army would leave Caesar defenceless before his enemies. Caesar chose Civil War over laying down his command and facing trial. The triumvirate was shattered and conflict was inevitable.

Pompey initially assured Rome and the senate that he could defeat Caesar in battle should he march on Rome. However, by the spring of 49 BC, when Caesar crossed the Rubicon river with his invading forces and swept down the Italian peninsula towards Rome, Pompey ordered the abandonment of Rome. Caesar's army was still under-strength, with certain units remaining in Gaul, but on the other hand Pompey himself only had a small force at his command, and that with uncertain loyalty having served under Caesar. Tom Holland attributes Pompey's willingness to abandon Rome to waves of panicking refugees stirring ancestral fears of invasions from the north. Pompey's forces retreated south towards Brundisium, and then fled to Greece. Caesar first directed his attention to the Pompeian stronghold of Iberia but following campaigning by Caesar in the Siege of Massilia

 in 48 BC despite outnumbering Caesar's forces two to one. Pompey fled again, this time to Egypt, where he was murdered in an attempt to ingratiate the country with Caesar and avoid a war with Rome.

Pompey's death did not see the end of the civil wars since initially Caesar's enemies were manifold and Pompey's supporters continued to fight on after his death. In 46 BC Caesar lost perhaps as much as a third of his army when his former commander Titus Labienus

"The Parthians began to shoot from all sides. They did not pick any particular target since the Romans were so close together that they could hardly miss...If they kept their ranks they were wounded. If they tried to charge the enemy, the enemy did not suffer more and they did not suffer less, because the Parthians could shoot even as they fled...When Publius urged them to charge the enemy's mail-clad horsemen, they showed him that their hands were riveted to their shields and their feet nailed through and through to the ground, so that they were helpless either for flight or for self-defence."

Despite his military success, or probably because of it, fear spread of Caesar, now the primary figure of the Roman state, becoming an autocratic ruler and ending the Roman Republic.

In response Trajan again marched into Dacia, besieging the Dacian capital in the Siege of Sarmizethusa, and razing it to the ground. With Dacia quelled, Trajan subsequently invaded the Parthian empire to the east, his conquests taking the Roman Empire to its greatest extent. Rome's borders in the east were indirectly governed through a system of client states for some time, leading to less direct campaigning than in the west in this period.

Jewish revolts (66–135)


The first Jewish-Roman War, sometimes called The Great Revolt, was the first of three major rebellions by the Jews of Judaea Province against the Roman Empire. Judea was already a troubled region with bitter violence among several competing Jewish sects and a long history of rebellion The Jews' anger turned on Rome following robberies from their temples and Roman insensitivity – Tacitus says disgust and repulsion – towards their religion. The Jews began to prepare for armed revolt. Earlier successes including the repulse of the First Siege of Jerusalem and the Battle of Beth-Horon

. Due in large part to their employment of powerful heavy cavalry and mobile horse-archers, Parthia was the most formidable enemy of the Roman Empire in the east. As early as 53 BC, the Roman general Crassus had invaded Parthia, but he was killed and his army was defeated at the Battle of Carrhae

Trajan also campaigned against the Parthians and briefly captured their capital, putting a puppet ruler on the throne, but rebellions with the province and the Jewish revolts in Judea made it difficult to maintain the captured province and the territories were abandoned.

Though the crisis of the third century was not the absolute beginning of Rome's decline, nevertheless it did mark a severe strain on the empire as Romans waged war on one another as they had not done since the final days of the Republic. Within the space of a single century, twenty-seven military officers claimed themselves emperors and reigned over parts of the empire for months or days, all but two meeting with a violent end. The time was characterised by a Roman army that was as likely to be attacking itself as an outside invader, reaching a low point around 258 AD. Ironically, while it was these usurpations that led to the break up of the Empire during the crisis, it was the strength of several frontier generals that helped reunify the empire through force of arms.

Collapse of the Western Empire (402–476)



Many theories have been advanced in explanation of the decline of the Roman Empire
Decline of the Roman Empire
The decline of the Roman Empire refers to both the gradual disintegration of the economy of Rome and the barbarian invasions that were its final doom...

, and many dates given for its fall, from the onset of its decline in the third century to the fall of Constantinople in 1453. Militarily, however, the Empire finally fell after first being overrun by various non-Roman peoples and then having its heart in Italy seized by Germanic troops in a revolt. The historicity and exact dates are uncertain, and some historians do not consider that the Empire fell at this point. Disagreement persists since the decline of the Empire had been a long and gradual process rather than a single event.

The Empire became gradually less Romanised and increasingly Germanic in nature: although the Empire buckled under Visigothic assault, the overthrow of the last Emperor Romulus Augustus
Romulus Augustus
Romulus Augustus , more known by his nickname Romulus Augustulus , was the last Western Roman Emperor reigning from the 31 October 475 until his deposition on the 4 September 476...

 was carried out by federated Germanic troops from within the Roman army rather than by foreign troops. In this sense had Odoacer not renounced the title of Emperor and named himself "King of Italy" instead, the Empire might have continued in name. Its identity, however, was no longer Roman – it was increasingly populated and governed by Germanic peoples long before 476. The Roman people were by the fifth century "bereft of their military ethos" and the Roman army itself a mere supplement to federated troops of Goths, Huns, Franks and others fighting on their behalf.

Rome's last gasp began when the Visigoths revolted around 395 AD. Led by Alaric I

The Battle of Verona was fought in June of 403 by Alaric's Visigoths, and a Roman force led by Stilicho. Alaric was defeated and subsequently withdrew from Italy....

 and again defeated Alaric, forcing him to withdraw from Italy.

In 405 AD, the Ostrogoths invaded Italy itself, but were defeated. However, in 406 AD an unprecedented number of tribes took advantage of the freezing of the Rhine to cross en masse: Vandals, Suevi, Alans and Burgundians swept across the river and met little resistance in the Sack of Moguntiacum and the Sack of Treviri, completely over-running Gaul. Despite this grave danger, or perhaps because of it, the Roman army continued to be wracked by usurpation, in one of which Stilicho, Rome's foremost defender of the period, was put to death.

It is in this climate that, despite his earlier setback, Alaric returned again in 410 and managed to sack Rome
Sack of Rome (410)
The Sack of Rome occurred on August 24, 410. The city was attacked by the Visigoths, led by Alaric I. The Roman capital had been moved to the Italian city of Ravenna by the young emperor Honorius, after the Visigoths entered Italy....

, but some historians view 410 as an alternative date for the true fall of the Roman Empire. Without possession of Rome or many of its former provinces, and increasingly Germanic in nature, the Roman Empire after 410 had little in common with the earlier Empire. By 410 AD, Britain had been mostly denuded of Roman troops, and by 425 AD was no longer part of the Empire, and much of western Europe was beset "by all kinds of calamities and disasters", coming under barbarian kingdoms ruled by Vandals
Vandals
The Vandals were an East Germanic tribe that entered the late Roman Empire during the 5th century.

Odoacer
Odoacer , also known as Odovacer, was a Germanic foederati general and the first non-Roman ruler of Italy after AD 476.

 and the Goths continued to fight over Rome and the surrounding area for many years, though by this point Rome's importance was negligible. Following years of grinding war the city was by 540 AD near-abandoned and desolate with much of its environment turned into an unhealthy marsh, an inglorious end for a city that once ruled much of the known world.

At this point in time, the Eastern Roman Empire stands alone, and events in Roman military history fall under the category of Byzantine military history.
