Roman Imperialism

For centuries, Roman legions have marched from their city upon the seven hills conquering the nations around them. One by one, the mighty ancient monarchies fell under Roman domination. At its height, this empire stretched from the lush green hills of Britannia, through the thick forests of Germania, and into the hot desert sands that stretched from Africa all the way into Judea and Syria. With these newly gained territories, Rome became more and more prosperous, as their resources accumulated through the decades. War and campaigns became a source of income for the empire. This sudden occurrence of the inevitable expansion of Rome can be traced back from the simultaneous threats of the Punic and Macedonian Wars, most notably, the period after Second Punic War to the end of the Third Macedonian War, from 201 to 168 BCE. Facing enemies on both sides of the Italian peninsula, Rome took a policy of “defensive imperialism” and soon defeated both Carthage and Macedonia. Rome soon found itself prosperous due to the sudden influx of wealth gained by her defeated enemies – the phenomenon of Roman Imperialism had begun and had taken shape. Although the Roman Empire was vast at its apex, there was never an expansion policy in the beginning, as the Roman Imperialism was nonexistent then. By only defending Rome, they have consequently gained much of the territories lost by their foes. With these new rich resourceful territories in their control, it was then the realization of building an empire began. And so, their inevitable empire had begun to take shape.
When one tries to analyse the origins of Roman Imperialism and the reasons behind it, there are several factors one must look into, such as early Roman expansion, the origin of the Punic and Macedonian Wars, the emergence of client states, and how Roman society itself reacts to its own territorial expansions. The reason why Rome decided to expand its city from its location on top of the seven hills, and to dominate the Italian peninsula, was the same reason it expanded into the Mediterranean world. Those were the societies that flourished around the city that would one day become either a close ally or a brutal enemy. The first to oppose young Rome was another city along the Tiber River, which bore the name Veii. In a struggle that lasted decades long, the fight for dominance over the Tiber River valley finally ended, with Rome being the victor. However, war was far from over.
From the northern borders, Rome’s first taste of the Gallic tribes poured over from the Alps. Unable to defeat those enemies, the northern invaders broke through the walls of Rome and pillaged the city. It was during that invasion in which the Romans learned a tremendous lesson. What had hurt Rome the most was not the plunder, but “her pride and prestige.” It was because of that invasion, that past allies took advantage of her weaknesses and launched attacks of their own upon the city. Rome never faltered in fending off every attack. Thick walls were raised around the city. Not one foreign invader will ever again set foot onto Roman soil within the walls for another few centuries. One by one, Rome absorbed other nations on the Italian peninsula into its dominion. It was not long before the entire Italian peninsula became the territory of Rome itself. Rome forced their past “allies” into “supplying auxiliary contingents” into its army. Rome has grown from a small village to a large nation dominating all of Italy. Their sight then drifted south towards the jewel of the Mediterranean – Sicily.
Nevertheless, the largest turning point in Roman expansion was during the end of the Second Punic Wars. Rome’s biggest rival, Carthage, was finally defeated and much of what used to be the Carthaginian territories had been annexed into Roman rule. Rome was now an unrivalled power in the western Mediterranean world as their sight turned eastwards towards the former Alexander the Great’s Macedonian empire.
With the death of Alexander in the year 323 BCE, the Macedonian Empire was split between its many generals. In Egypt, the Ptolemaic Kingdom had spread its influence. Also, in a territory spreading from the Aegean to Afghanistan , there was the Seleucid Kingdom that dominated the deserts. Macedonia itself retained its territories in Greece and Thrace. The troubles in the eastern Mediterranean first began during the climatic days of the Second Persian Wars when the king of Macedonia named Philip V made an alliance with Hannibal. With that pact signed, Philip V launched campaigns against Roman possessions in Illyria (modern day Croatia, Bosnia and Serbia). However, due to an alliance by Rome and the Greek states of the Aetolian League, Philip V had to back down from the war. That became known as the First Macedonian War, which lasted from 215 to 205 BCE. It was the first of four conflicts that will open the way for Roman supremacy in the east.
Although the first conflict with Macedonia was not due to Roman interest in the east but a war to prevent Philip V from joining forces with Hannibal, the Second Macedonian War (200 to 196) was the struggle “that really signed the birth certificate of Roman imperialism.” Rome took part in this war because of commercial reasons – they had taken interest in overseas trading from the local Greek cities in southern Italy and Sicily. Philip V however, had been causing several disturbances in these trading routes. Rome would benefit a lot economically with a war against Greece and Macedonia as well. Greece would become a source of intelligent and educated slaves, which was a growing demand in the Roman market since the First Macedonian War. Furthermore, Greece and Macedonia were rich with valuables and treasures that attracted many Romans from all classes.
In order to protect the interests of the Roman economy and the security of Rome itself, in the year 200 BCE, Rome launched its second campaign against Philip V’s Macedonian Empire. This became the start of a new policy known as “defensive imperialism.” What this policy does was to keep the peace throughout the sphere of influence within the Roman dominated Mediterranean world both on land and sea. Rome, in a way, played the “policeman” over what would later become “client states”, and then annexed as provinces.
What spurred this “defensive imperialism” policy was due to the outrage from the Roman populace during the Second Punic Wars, when Carthaginian General Hannibal Barca invaded the Italian peninsula. A force no less than twenty thousand infantry and six thousand cavalry descended down the slopes of the Alps and ravaged the Italian peninsula. Gaining support from cities in the region, they defeated legion after legion in the battles of Trebia, Lake Trasimene, and Cannae. Due to the threats the Carthaginian-Macedonian alliance posed, it was in Rome’s best interest to send their troops east when the Carthaginian forces were wiped out in the battle of Zama.
What really decided the victor of the war was the decisive battle at Cynoscephalae. Although the Macedonian phalanx were superior to the Roman legionnaires in close combat and in their choice of positioning (they fought on high grounds) , the table was turned to Roman favor when “a quick thinking tribune detached some maniples from the rear of the successful Roman right and attacked the ponderous phalanx of the Macedonian right wing from behind.” This move showed that Roman legions were more flexible in their tactics by making changes according to the battle situation. By the year 196 BCE, Rome had “liberated” Greece and the general who led the campaign, T. Quinctius Flamininus, declared the independence of the Greek states. However, this declaration of independence did not give the Greeks total liberation – what the Greeks really became was a client state of Rome. These client states that Rome obtained throughout the period between the Second Punic Wars and the Third Macedonian Wars would later be annexed into Roman provinces sometime in the 140s BCE.
Territorial expansion for Rome not only benefited only the upper class patricians or the aristocracy, but also the common people, better known as the plebeians. War was a source of income for Rome. Every new territory they conquer, there were valuables for generals to distribute among their men. Any leftover “booty” could also be spent on public works, such as temples. Because of these treasures gained from conquering territories, for the ordinary soldier, war was a quick way for many to gain wealth.
Like the soldiers of today, Roman soldiers also received awards for valour. There were crowns awarded for different accomplishments. For example, victors of sea battles received a crown decorated with ships, while someone who was an exceptional cavalry soldier received a crown decorated with the theme of horses. The highest award for outstanding achievement in the line of duty is a “crown of oak leaves, which was considered a much greater honour than all the crowns of silver and gold.” This was known as the “Civic Crown” and those who received it wore it proudly on their heads.
With the Third Macedonian War ending with a decisive victory at the Battle of Pydna, the Romans got rid of the ruling monarchy in Macedonia and split the nation into four independent republics with limited rights. In addition, these territories had to pay an annual tribute to Rome. In Greece, one thousand of the ruling class citizens were purged and deported to Italy. Although none of the territories were annexed until the year 148 BCE, Rome still kept an iron fist over the Hellenistic world. Rome was getting more and more wealthy. Looking at the Mediterranean map, the Romans soon realized that after the Punic and Macedonian wars, Rome’s territorial size had grown from 27,000 square kilometers to 55,000 square kilometers. The empire was slowly taking shape and further conquest would bring additional wealth to the already prosperous city. Expansion was inevitable.
In conclusion, Rome never had a policy of imperialism and expansion in the beginning. It was the threat from the Punic and Macedonian Wars that caused the formation of this predestined empire. Rome expanded only to protect herself from the hostile nations around them – defensive imperialism. It was the promise of wealth and plunder that manipulated the Romans into stretching their frontiers to their limits. From 168 BCE and beyond, the golden eagle of Rome will bring almost all of Western Europe and the Mediterranean World under the control of one city – Rome. Without this inevitable empire taking shape, the world today would have been dramatically altered.
