Roman Legion

Why Study Rome?

Americans have focused on comparisons between Rome and America twice in American history.  The first time was during the period from before the Revolution to after the ratification of the Constitution and Bill of Rights, when the founding fathers and others looked to the Roman Republic for ideas and inspiration on how to structure the new government. After the American Revolution, the founding fathers, having read the Roman authors detailing the collapse of the Roman republic, worried about internal threats to the survival of their new republic.  

The second time was when the United States became a superpower, especially after WWII, and then again after the collapse of the Soviet Union in 1991. Commentators compared America to the Roman Empire at the height of its power. There was some discussion about how America became a permanent warfare state and how it affected domestic democracy and civil society.

And now a third time. Have Americans and their leaders concluded that the costs of maintain global leadership and power are too high? That the creation of the global economy under American rules and protection is responsible for domestic economic problems including stagnant and declining incomes of many Americans while a small elite controlling and managing global corporations are becoming very rich? Will the resulting domestic political conflicts lead to fewer resources and lessened commitment to the global order America created? In short, can America, like Rome, be both a republic and a global power?

It is difficult to appreciate today how extraordinary was the Roman Republic. The city was governed for 500 years without a king or conqueror. Power was not concentrated in one person; leaders were elected. Nowhere else in the world, except in parts of Greece and overseas Greek cities, was there the idea of citizenship. Nowhere else could power be shared and transferred peaceably through elections. Nowhere else were conflicts resolved through compromise and according to rules of law. Nowhere, not even Athens, was more democratic, in terms of the percent of the male adult population who voted and enjoyed the rights of citizenship.

Many of the American founding fathers read Roman historians. Roman historians generally praised Rome’s republic, its political structure, and its underlying civic and individual virtues. They condemned Rome’s subsequent emperors as tyrants and their society as corrupt. This learning had a profound effect on American political thinking and governmental institutions.

Historians like to write about the “decline and fall of the Roman Empire.” But of more historical relevance for the United States now is the last 100 years of the Roman Republic (146-49 BC). It was during this period that Roman legions, after the final destruction of Carthage, conquered western Europe and the Mediterranean world. The Republic created the Empire. But the consequences of these military victories undermined and then destroyed the Republic. 

How did this happen?  Could it have been avoided?  What does this say about the relationship between becoming an imperial power, military power, internal security and liberty? How does being a global superpower impact domestic society and politics? Can a republic become a global superpower and survive as a republic? Are there any possible lessons to be learned from Rome’s experience?

The Suicide of the Roman Republic:  The Building of Empire and the Projection of Military and Political Power

The Roman Republic did not “fall” or “collapse.” It did not fail because of one dramatic event such as Julius Caesar and his legions crossing the Rubicon River in 49 B.C., invading Rome and later declaring himself Dictator. The Roman Republic weakened and then committed suicide, or was killed, over a long period of time.

Rome, like America, began its modern history by overthrowing a foreign king and declaring a republic. But even before, America had a long history of local self-government; the American Revolution was partly caused by England’s attempt to impose more control on its American colonies. The subsequent republican government was partly modeled on Rome’ republic. This is not surprising. Both countries were suspicious of concentrating power in one man and wanted to diffuse power. But not too far; both believed that political power and government offices should rest in the hands of a political elite with “civic virtue.” The center power was the Senate, whose members were part of “patrician” clans. This political elite, for a long time, believed in “civic virtue,” which included ideas about contributing to the common good, focusing on national interests, and gaining personal status (gravitas) by contributing to the welfare of the state. In America, the man who embodied this ideal was George Washington. There is a statue of him wearing a Roman toga.

The Roman Republic lasted approximately 500 years, If America’s experience with self-government begins in the early 1600s, America has had some form of representative government for about 400 years.

One way Rome grew, as did America, was taking in immigrants, no questions asked. In the long run, immigrants were a source population and economic growth, new citizens, and soldiers. In America, immigrants played a similar role.

Both republics were founded – their basic constitution and laws were written, representative institutions established – when both countries were agrarian societies based on independent landowning farmers. All were citizens. Citizens had rights under Roman law similar to the rights of American citizens. While candidates for political offices usually came from the patrician clans, they were elected by the citizens. 

Citizens also had obligations. The most important was that all citizens were required to serve as soldiers. For centuries, the Roman army was a part-time militia. Citizens were called up after planting, fought against other Italian towns or tribes during the summer or if a military emergency, and were then sent home for harvesting. There was no standing (permanent) army but all male citizens were a permanent military reserve, an obligation that could last a lifetime. Armies were led by one or two elected consuls (the highest political office, somewhat similar to the American president) who served for one year.

The American version was local militas. In colonial times, all white males beween the ages of 16 and 60 were required to be members of local militas. Required time of active service was usually 30-60 days and militas only fought locally. They chose their officers. They could be activated if there was a local threat such as fighting Indians on the frontier or the British in the Revolutionary War. After the Revolution, Americans opposed the idea of a permanent standing army. Until December 7, 1941. 

For hundreds of years, republican Rome expanded by fighting local enemies on the Italian peninsula. The American equivalent was expanding across the American continent and avoiding overseas conflicts. Any fighting that occurred before the Civil War, usually against native Americans, was done by locally-raised militias. Jefferson, who approved the Louisiana Purchase, said that America was creating “an empire of liberty.”

As Rome conquered surrounding towns and territories, some of them were given the choice of becoming subordinated allies. In exchange for some privileges, including local rule and citizenship rights for local elites, allies were expected to provide “auxillary” military forces to the Roman army. Rome drew on this expanding manpower pool. Often, in both the Republic and Empire, the number of auxillary troops were more or about the same as the number of soldiers who were Roman citizens in legions.

Similarly, America did not treat purchased or conquered territory as colonies. Most of the existing population and new America settlers enjoyed the same rights as Americans in the original states. New states were formed with the same government structure and political rights as the older states.

After WWII, the United States, like Rome, was able to turn former enemies into allies. American and allied military forces were combined into military structures like NATO, dominated by the United States.

Rome and Carthage:  The Beginning of a Superpower

As Rome became the dominant power in Italy, Carthage became the dominant economic and trading power in the western Mediterranean. Rome had an army but no navy; Carthage had a strong navy to protect its merchant ships and Mediterranean trade. Rome and Carthage had a long history of treaties and alliances with each other. They had different sphere of influence with no important geopolitical areas of conflict.

Rome and Carthage finally came into contact in Sicily after Rome conquered southern Italy. Sicily was close to both Rome and Carthage, sat astride important shipping lanes in the Mediterranean, and was a source of grain for Rome. Both Rome and Carthage had city-state allies in Sicily, although most of Sicily was dominated by Carthage and the independent city-state of Syracuse. As allied troops demonstrated in World War II, Sicily was a convenient staging area for invading southern Italy. Carthage in Sicily and Rome in southern Italy were now only a few miles apart.

The Punic Wars between Rome and Carthage lasted off and on from 264 BC until 146 BC. The First Punic War was during 264-241 BC, the Second between 218-202 BC, and the Third between 149 and 146 BC. The greatest danger to Rome was the Second Punic War, when Hannibal invaded Italy, defeated one Roman army after another, and threatened Rome and its Italian allies.

Carthage could only defeat Rome if they built an army, invaded Italy and threatened Rome. Rome could only defeat Carthage if they could build a navy and defeat the Carthaginian navy, thus clearing the way for Roman legions to invade North Africa and conquer Carthage.  

Rome fought a life or death struggle against Carthage for the dominance of the western Mediterranean. Rome eventually triumphed over Hannibal and Carthage because of its ability to mobilize all of its citizen manpower supplemented by troops from Italian allies, appoint long-term commanders and officers, create a navy, and send its full-time legions overseas. By the end of the Third Punic War, Rome was a strong military force in the Mediterranean world and could project its military over long distances. 

In the period before the Punic Wars, Rome typically conscripted yearly enough men to fill two legions, about 10,000 men. The size of this force was sometimes doubled by military quotas Rome imposed on its Italian allies. During the Second Punic War, large Roman armies were annihilated again and again by Hannibal and had to be rebuilt. At the battle of Cannae, it is estimated that the Roman army had 80,000 men (and over 60,000 of them were killed by Hannibal’s forces). By the end of the Second Punic War, the Roman army had an estimated 100,000 men. From then on, Roman legions would fight and be stationed throughout the Roman Empire. Throughout the period of the Roman Empire, Rome tried to maintain a permanent standing army of over 200,000 men. This put economic and administrative strains on Rome that Rome’s tax system and republican institutions found it difficult to manage.

A rough analogy might be America just before its entrance into World War I in 1917 (very small and unprepared standing army), World War II, and the Cold War with the Soviet Union until the collapse of the Soviet Union in 1991. Carthage was Rome’s equivalent of the combination Germany and Japan in World War II and then the Soviet Union during the Cold War. Because of the threat of the Soviet Union, America could not demobilize its armed forces and return to isolationism. Also, for the first time, America had to station large forces overseas, especially in Europe. 

Rome as a Superpower

Again, almost all of the Roman Empire was conquered while Rome was still a republic. The “Roman Empire” as a form of government substituted monarchical rule for a combination of oligarchy and representative democracy. 

In the last 100 years of the Roman Republic, from the end of the long war with Carthage to Julius Caesar establishing a dictatorship in 49 BC, Roman legions and auxillaries conquered Spain, France, the Lowlands, North Africa, the Balkans, Greece and Macedonia, Turkey and Asia Minor to the Black Sea, and most of the eastern Mediterranean as far as Syria. In the middle of these conquests, Rome stopped a major invasion of Italy by Germanic tribes, fought a major civil war with its Italian allies and defeated Mithridates, a formidable opponent in Asia Minor. These conquests brought great wealth to Rome, with serious domestic political consequences. 

Roman legions often fought more than one war at the same time. Conquests and pacification often took many years, sometimes decades. Rome needed a much larger army able to campaign for long periods of time and permanently occupy distant territories. Short-term conscripted citizens were replaced by long-term professionals, who signed up for as long as 25 years. The Roman army transitioned from a conscripted militia of short-term citizen soldiers to a well-trained, well-equipped permanent force of professional soldiers and officers. As did the American army after Vietnam.

Rome’s antiquated tax system had difficulty paying for the greatly expanded costs of the army. New legions were sometimes financed by private individuals, usually from generals of the patrician class (Sulla, Pompey, Caesar), to further their ambitions and power. 

Legionaries were often loyal to their general, not Rome, and expected to be rewarded with booty, bonuses, and land. Conquered territories were often considered power bases for the general and his legions that conquered them.

In the last decades of the republic, Roman generals and their legions fought other Roman generals and their legions for control of the republic. Marius vs. Sulla. Pompeii vs. Caesar. 

Later in the Empire, Roman legions were increasingly used to patrol and defend frontiers. The most important frontiers were far from Rome – the Rhine River, the Danube River, and roughly the Tigris-Euphrates Rivers in Syria and Iraq. Two thousand years later, American troops fought and stood guard along some of the same frontiers.

Domestic Consequences of the Empire

The new wealth and the military needs of the Empire weakened the foundations of the republic. The patrician class of senators and their clients seized much of the increased wealth, first as military commanders receiving much of the immense booty. After a province was established, the Senate appointed provincial governors and staff from their own ranks. This was another opportunity to get rich quickly. Some of this private wealth was spent back in Rome to buy power and influence. Some of it was used to buy large tracts of land in Italy to create large plantations usually worked by slaves. Senators and ambitious politician/generals used bribery, gangs, assassination and patronage to control and manipulate the Roman population and their popular assembles and elections.

As earlier in the Republic, private influence was also gained by sponsoring public buildings, lavish games, spectacles, and entertainment for the increasing population of Rome; this was a common way to gain influence with the volatile mobs and plebs in the streets. But now the elites also enjoyed “conspicuous consumption,” a higher level of luxury.

During this transition period, there was an explosion of population of Rome, going from about 200,000 to one million in about 50 years. Many of the new residents were citizen-farmers and their families who had lost their land to creditors, unemployed ex-legionaries, refugees, and slaves, the poor and dispossessed, first from Italy and then from all parts of the Empire. But the Roman government did not create new institutions to govern or manage the larger city and its unemployed. Instead, generals and politicians attempted to curry favor with the mobs with free bread and spectacular entertainments. 

At the beginning of the final century of the republic, wealthy elites were seen as venal, corrupt and refusing to share power with the people. Demagogues arose to articulate plebeian anger and frustration. The Senate was challenged by more aggressive tribunes, who were elected by the people and represented their interests. The Senators tried to reduce the power of the tribunes through coopting them, corrupting them, or paying to have tribunes sympathetic to the Senate elected in the first place. Political tactics included mob violence and assassination; the most famous of the tribunes were killed by a mob of senators.

Rome was able to provide security along trade routes and sea lanes. More long-distance trade was made possible by the increased security of the Mediterranean world. Rome increased its imports of grain and other products to feed its growing urban population. Rome’s wealthy upper-classes imported luxury goods. 

Local citizen farmers found it increasingly difficult to compete with the cheaper imported grain and other agricultural products. Many went into debt and lost their farms. Wealthy patricians were able to seize much of this land. Dispossessed farmers drifted into Rome and other cities, became part of the unemployed poor, joined the army as professional soldiers, or became tenant-farmers or laborers on the landed estates of the wealthy. Patricians increasingly used slaves to work their large plantations. It is likely that this new wealth and income was concentrated in the hands of a small group, mostly patrician clans. The Republic base of citizen-farmers was fatally weakened.

The Empire and the new Roman “global economy” created new opportunities for a class called publicani. The Roman government “outsourced” much of the economic and financial management of the Empire to the publicani. This group of imperial merchants and moneylenders grew rich handling long-distance trade, collecting taxes in the provinces, supplying the army, and managing the Empire’s finances. Government contracts were given to influential senators, who subcontracted to their publicani clients. Primitive limited liability corporations were created to spread risk.

As this concentration of power and wealth played out, the hard-won political privileges and power the plebeian classes gained earlier were eroded. Successful generals dominated the Senate and had themselves elected consuls for long periods of time or dictators (rulers with extra-legal authority).

The link between Rome’s citizens and citizen army was broken. Generals pursued personal glory and power through military conquest. Ambitious patricians and newly-wealthy generals financed the creation of new legions. Professional soldiers were recruited from the lower classes and the provinces. Politician/generals such as Marius, Sulla, Pompey, and Julius Caesar used wealth and booty captured in military campaigns to reward their legions and buy political power and influence when they returned to Rome. Legions, far from Rome, shifted their allegiance from Rome to their commanders. Roman legions loyal to one general fought wars against Roman legions loyal to another general. Successful generals became consuls or dictators with emergency powers. This dynamic reached its climax when ambitious generals like Sulla and Julius Caesar committed the ultimate treason to the Republic by marching their legions into Rome and seizing power. After decades of fighting among legion armies, Julius Caesar became undisputed leader (Dictator) of Rome. He appointed new senators, men to fill all political, religious and legal posts in Rome, and provincial governors and their staff. His assassination by republican Senators cut his dictatorship short. But Caesar’s adopted successor, Octavian (Julius Caesar’s great-nephew, later named Caesar Augustus) became the first emperor in all but name. In an act of historical symbolism, part of his campaign to kill anyone with republican sympathies, Augustus ordered his thugs to kill Cicero, the great republican orator. The Republic was dead.

The Last Act. Octavian and Marc Antony

Octavian was a poor military commander but fortunately for him, a childhood friend named Agrippa turned out to be an excellent general. Agrippa won the wars.

Octavian was a genius at political propaganda. He convinced many Romans he was saving the republic while he was “hollowing out” its republican institutions.  His final conflict was with Marc Antony, Julius Caesar’s top commander.  What was the usual Roman conflict for control, Octavian cleverly created support against Antony.

Antony lived in Egypt with Cleopatra (queen of Egypt) and controlled the eastern half of the Roman Empire. It was the wealthier half. Octavian started a propaganda campaign portraying Antony as under the influence of a foreign queen and no longer a true Roman. Octavian spread rumors that Antony wanted to move the capital of the Roman Empire to Alexandria in Egypt. In the end, Octavian’s forces under Agrippa defeated Antony. Antony and Cleopatra committed suicide. Octavian was the undisputed ruler of the new Roman Empire.

The End of the Roman Republic

Octavian (Caesar Augustus) did not destroy the institutions of the Roman Republic.  He finished “hollowing” them out, completing the process began by his uncle Julius Caesar and Caesar’s predecessors (Marius and Sulla, Caesar’s former commander). 

Augustus was able to do this with a minimum use of violence but only after 13 years of warfare and the elimination of political rivals and defenders of the Republic. Augustus ruthlessly hunted down his uncle’s assassins and anyone else suspected of republican sympathies. Many senators were killed and Augustus appointed replacements. The Senate and elected magistrates continued to exist but were totally subservient to Augustus. He wrote the laws. Like his uncle, he appointed the Senators and the administers of Rome. Caesar Augustus, not the Senate, appointed the generals and provincial governors who ruled the empire. He named his successor. The Senate lost all domestic political power. 

Augustus curtailed citizen rights, especially the right to free speech and dissent. He punished anyone who had the courage to criticize him. He was above the law and any legal constraint.

In summary, during the last decades of the Roman Republic there was a breakdown of a sense of community, political compromise and sharing power and responsibilities, and “civic virtue.” Rome’s republican institutions were not strong enough to stand up to the new opportunities for personal power and wealth presented by military success and the creation of conquered territories.

The Roman people were tired of decades of internal violence and political chaos. Augustus promised a return to the “domestic tranquility” destroyed by the creation of the Roman Empire. He attempted to legislate traditional morality and republican virtues to a society dominated by a wealthy elite, a society that was no longer republican. He failed.
