Treaties between Rome and Carthage
|This article needs additional citations for verification. (August 2008)|
The treaties between Rome and Carthage are the four treaties between the two states that were signed between 509 BC and 279 BC. The treaties influenced the course of history in the Mediterranean, and are important for understanding the relationship between the two most important cities of the region during that era. They reveal changes in how Rome perceived itself and how Carthage perceived Rome, and the differences between the perception of the cities and their actual characteristics.
As city-states that became empires, Rome and Carthage eventually found it necessary to formalise their reciprocal interests and zones of influence. For centuries, the two operated side by side, even as allies. Their economic interests and methods of expansion were different: Rome did not look to the sea, engaged first in defending itself against the neighbouring Samnites, Etruscans, Gauls, and Greeks, and then in conquering them; Carthage, lacking a real civic army and repelled in Sicily by the Greeks, appeared indecisive regarding its expansion strategy: while the aristocratic party was inclined to extend the power of the city into surrounding lands, the commercial party was more interested in exploiting trade routes and markets. By stipulating and observing four main treaties, the relationship between Rome and Carthage was one of tolerance for centuries. Carthage and Rome also concluded two treaties to end the First and Second Punic War in 241 BC and 201 BC, by which time the relationship between the powers had changed considerably.

Carthage was founded in 814 BC by Phoenician colonists from Tyre, and by the 6th century BC the sailors and merchants of Carthage were known throughout the western Mediterranean. In the 4th century BC, following a series of military conquests, Carthage controlled many territories west of the gulf of Sirte in present-day Libya, and much of the coasts of Numidia and Iberia. The coasts of Sardinia and Corsica were already under Carthaginian control when the city-state attempted, in three wars between 480 and 307 BC, to conquer Sicily. These attempts were stopped by the Greeks, who had, by then, heavily colonized the island. Primarily interested in commerce, Carthage had no standing army, and mostly used mercenary forces composed of Numidian cavalry, Libyans, and Iberians.
Rome was founded only seventy years after Carthage (in 753 BC, following Varronian chronology). For the first several centuries of its history, Rome was involved in a lengthy series of wars with its neighbours, which resulted in the Roman army's specialization in land warfare. The Roman economy and social structure began to incorporate the results of these wars: taking loot or tribute, redistributing conquered land, and sometimes using subjugated peoples as military allies (socii). With respect to maritime commerce, the Romans simply entrusted themselves to the Etruscan and Greek fleets.
In the 2nd century BC, a great line divided the commerce of the Mediterranean: the Aegean, Adriatic and Ionian seas were largely controlled by the maritime cities of the Greeks (in Greece, Asia Minor, and, after Alexander the Great, Egypt), while the western Mediterranean was the commercial zone of the Carthaginians, with the exception of the Tyrrhenian Sea, which Carthage shared with the Etruscans and the Greek colonies of southern Italy.
First treaty 509 BC
The first treaty between the two city-states was signed the year the Roman Republic was founded, in 509 BC as dated by the Varronian method. The calculations of Polybius, a Greek historian whose calculations are based on the years of the Persian expedition against the Greek free cities, produced a slightly different date; he wrote that the events of the treaty took place "twenty-eight years before the passage of Xerxes into Greece". Xerxes, the king of Persia, crossed the Hellespont with his armies in June, 480 BC.
During the war with Ardea, following the overthrow of Tarquin the Proud, Rome found that it needed to secure itself and its supplies, which were controlled for the most part by Greek and Etruscan merchants, since the Etrsucan Cerveteri and its port of Pyrgi supplied Rome. Rome therefore tried to gain the support of the Carthaginians who by that time were already operating in Cerveteri, as evidenced by votive writings found in Etruscan and Phoenician.
At the same time, Carthage was engaged in fighting the Greek colonies that had spread from Greece across the western Mediterranean. The presence of Greek cities along the coasts of southern Italy and the eastern part of Sicily limited Phoenician commerce to the region's interior. In Spain and Provence, Carthage fought to compete with Phocaean colonies, and in Sardinia and Corsica, Carthage was joined by the Etruscans in their competition with the Phocaeans, resulting, subsequently, in the Phocaeans being driven out, Corsica and the Tyrrhenian becoming Etruscan, and Sardinia and the western half of Sicily becoming Carthaginian (eastern Sicily would remain Greek for centuries). Additionally, in 510 BC, Carthage had to fight to hold off Spartan incursions into western Sicily.
Terms of the treaty
This treaty was signed between Rome and Carthage twenty-eight years before the invasion of Greece by Xerxes, according to Polybius. The treaty stated that there "shall be friendship between the Romans and their allies, and the Carthaginians and their allies" on the conditions listed below.
Conditions on Rome and her allies
The conditions imposed by the treaty on Rome and her allies were that
- They were not to sail past Cape Bello (i.e. into the gulf of Carthage), unless driven there by storm or enemies;
- If anyone was "driven ashore" he was only to buy or take what was needed for "the repair of his ship and the service of the gods", and had to leave within five days; and
- Merchants could operate in Sardinia and Libya only in the presence of a herald or town-clerk, and the sale would be secured by the state.
Conditions on Carthage and her allies
The conditions imposed by the treaty of Carthage and her allies were that
- They were not to attack certain settlements named in the treaty, that were "subject to the Romans";
- They were not to attack even townships not subject to Rome, and if they conquered one they were to "deliver it unharmed to the Romans";
- They were not to build fortresses in Latium;
- They could not stay the night in Latium if they entered the district armed; and
- In Carthaginian Sicily, Romans were to have the same rights as Carthaginians.
Per the treaty, Carthage did not renounce any military action except against a small territory, Latium, and maintained a free hand for action against the Greeks and Etruscans, both of whom were militarily and economically more powerful and dangerous than Rome.
In the graphic at right, the following areas are highlighted and labeled:
- The area was forbidden to Rome by the treaty. By then, Carthage with its navy had already blocked any competition beyond the channel of Sicily or along the African coast.
- The area not under direct Carthaginian control. In fact, Greek and Etruscan mariners sailed there freely; Carthage reserved the right to refuse competition, but "magnanimously" offered the Romans shelter in case of emergencies or bad weather.
- The area under Greek and Etruscan control.
Roman expansion, before the fall of Tarquin the Proud, was directed towards the Tyrrhenian coast to the southwest, and the Roman Republic was proclaimed while Tarquin's army was fighting Ardea. It can be supposed that Rome, with its small size, wanted to formalize the exclusion of competition from Carthage while it began pressuring the Greeks. Otherwise, the contrast of this diplomacy with the war against Ardea would not be so pronounced, nor would it make sense to specifically exclude Carthaginian fortresses.
Second treaty 348 BC
After 150 years of campaigning, Rome had conquered a good portion of Etruria, destroyed Veii, and repelled the Gallic invasion of 390 BC, although it felt threatened by the second Gallic invasion of 360 BC. Rome had been and still was shaken by internal strife, especially between the patricians and the plebeians for access to public office and therefore to political activity and the management of land and spoils of the incessant wars. Rome was also fighting the Ernici, the Volsci, the Tiburtini, and the Etruscans, and was preparing for battle with the Samnites, who were coming down from the mountains to raid rich Campania, which Rome also desired.
In Sicily and in southern Italy, where Dionysis the Great had created the beginnings of a unified state, Dionysius the Younger, his son, tried to enlarge his inheritance, but met with resistance from other Greek forces. A flurry of alliances, including some with the Carthaginians, led to the disintegration of Dionysius's power, and his deposition in 345 BC. Taranto, which had been left out of the fighting, grew in power, and other forces arrived from Greece. Rome was beginning to assert its influence in these struggles.
Carthage, after having closed the war with the Cyrenaica, thus stabilizing the eastern boundary of the Phoenician territory, had been always at war with the Greeks and in particular with Syracuse, for control of Sicily. It was also in conflict with the Etruscans, who, blocked by the Gauls from northern Italy, and by the Romans from Latium, applied themselves aggressively to the Tyrrhenian Sea to control traffic there.
Terms of the treaty
This second treaty was an attempt to copy the first treaty, with the addition of some cities. The Carthaginians added Tyre and Utica, while promising not to attack the coastal cities of Latium that had allied themselves with Rome. Similar to the first treaty, it stated that there "shall be friendship between the Romans and their allies, and the Carthaginians, Tyrians, and [the] township of Utica" on the conditions listed, and that Romans were allowed to trade and do business in the Carthaginian province of Sicily and in Carthage, and Carthaginians were allowed to trade and do business in Rome.
Conditions on Rome and her allies
- The Romans were not to maraud, traffic or found a city east of "the Fair Promontory, Mastia, Tarseium."
- If the Romans took prisoners, "between whom and Carthage a peace has been made in writing, though they be not subject to them", the Romans were not to bring them to any Carthaginian harbor. Additionally, if such a prisoner were brought ashore, and any Carthaginian lay claim to him, he was to be released.
- If a Roman took water or provisions from any district within the jurisdiction of Carthage, he was not to injure, while so doing, any between whom and Carthage there was peace and friendship. Violation of this rule was to be a public misdemeanor.
- A Romans was not to traffic or found a city in Sardinia and Libya, and could only take provisions and refit his ship. If a storm had driven him to one of those coasts, he was to depart within five days.
Conditions on Carthage, Tyre and Utica
- If the Carthaginians conquered any city in Latium that was not subject to Rome, they may keep the prisoners and the goods but were to deliver the town to Rome.
- If the Carthaginians took prisoners, "between whom and Rome a peace has been made in writing, though they be not subject to them", the Carthaginians were not to bring them to any Roman harbor. Additionally, if such a prisoner were brought ashore, and any Roman lay claim to him, he was to be released. In like manner shall the Romans be bound towards the Carthaginians.
- If a Carthaginian took water or provisions from any district within the jurisdiction of Rome, he was not to injure, while so doing, any between whom and Rome there was peace and friendship. Violation of this rule was to be a public misdemeanor.
Carthage saw Rome as a possible adversary that had resisted invasion and in war was proving itself potentially dangerous. Rome also controlled a large amount of territory, larger—if not richer—than its perennial rival Syracuse. Moreover, the fact that Carthage allowed Phoenician merchants to operate in Rome shows that the former did not fear commercial competition from Rome and that it could operate it own territories, while treating Rome as an upcoming potential client that should be put under its political control.
It is therefore to the credit of Carthaginian diplomacy that the revision to the 509 BC treaty imposed additional restrictions on Rome, written at a time when it was heavily engaged in military (and therefore financial) obligations. Additionally, the prohibition against Rome's founding of cities did not appear in the first treaty, and shows that Carthage may have caught on to the method of Roman expansion; commerce did not interest Rome as much as the control and exploitation of its territory. To the Romans, if an area was deserted it would be substantially occupied; if the area was inhabited, it would be conquered and forced to pay in assets and troops, and eventually to accept Roman or Latin colonies. This was probably foreign to the commercial mentality of the Carthaginians in 509 BC, who founded colonies almost exclusively to support warehouses.
Third treaty 306 BC
During this period, Rome was in control of most of southern Etruria and the territory of Campania, and was in the middle of its wars with the Samnites. Begun in 343 BC, these would not be concluded until 290 BC, and had become a regional revolt, with the populations of Latium and Etruria trying to free themselves from Roman rule.
There were other incidents causing unrest, in other parts of the region. Alexander the Great died in June, 323 BC, and the territory he had conquered was being fought over by the Diadochi, the generals of the Macedonian army; Egypt, Greece, Macedonia, Asia Minor, and Syria were involved in incessant wars that threatened peaceful trade; and Agathocles ascended the throne of Syracuse in 316 BC and began a campaign to rid Sicily of the Carthaginians, and in 311 BC, having been defeated in Sicily, carried the war to Africa before allying himself with Cyrenaica the following year.
In 303 BC, Rome and Taranto concluded a treaty that fixed the limits of Roman navigation at the Lacine promontory (see Capo Colonna) and by 306 BC Rome had come to an agreement with Rhodes, another city undergoing strong commercial expansion.
Existence and terms of the treaty
While Polybius claimed that this treaty never existed but was a forgery of the pro-carthagininan historian Philinus, recent research suggests that such a treaty did in fact exist. Philinus claimed that the treaty included Rome's agreement not to enter Sicily and Carthage's agreement not to set foot on the peninsula, i.e. the stipulations on Carthage did not change while Rome now found itself shut out of the Sicilian market.
Fourth treaty 279 BC
The Samnite Wars officially ended in 290 BC, and the subsequent actions of Rome within its territory had reduced the pressure of the Italian populace on the Greek cities in southern Italy, and in particular Taranto; the Italians themselves were being attacked by the Roman army. Taranto was experiencing a period of wealth and expansion, to the point of securing a treaty that limited Roman navigation (see above). In 282 BC, ten Roman ships appeared in Tarantine waters, violating the treaty, but they were either destroyed or forced to escape. When a Roman delegation was sent to request restitution for the ships and the captured prisoners, it was insulted, and war between the two states began in 281 BC. The Tarantines at first tried to form an anti-Roman league with the Italic populace, but it was considered to be insufficient, and thus, in 280 BC, they requested the assistance of Pyrrhus to lead the war against the Romans.
Pyrrhus arrived with an army of 25,000 men and 20 elephants in Taranto, when it was succumbing to the Roman army, and presented himself as the champion of Greece against the advance of the Italic barbarians. Pyrrhus' attack on Rome was heralded as a success: the Battle of Heraclea in Lucania against the legions under Publius Valerius Laevinus was won thanks to the use of elephants (which the Romans had never seen and called them Lucanian bulls ). In 279 BC, a second great battle, the Battle of Asculum, at Ascoli Satriano, was seen as a victory by Pyrrhus over the forces of the consuls Publius Supilcius and Decius Mus. This battle, however, exacted heavy losses on the victor, so great that it inspired the term "Pyrrhic victory". Pyrrhus subsequently returned to Taranto.
Syracuse remained at war with Carthage and, after the death of Agathocles, was further embroiled in a civil war. The former, trying to change its lot and taking advantage of the fact that Pyrrhus had married Agathocles' daughter, offered him the crown of Sicily in exchange for helping them throw off the Carthaginians. Pyrrhus accepted, partly to leave the peninsula and avoid the Romans. Pyrrhus landed in Sicily, and was successful in pushing the Carthaginians to the Lilybaeum on western coast. These manoeuvres by Syracuse and Pyrrhus prompted Carthage to sign the fourth treaty with Rome.
Terms of the treaty
The treaty contained the same provisions as the two earlier treaty, with the addition of the following.
- If Rome or Carthage make a treaty of alliance against Pyrrhus, the two states were to make it on such terms as not to preclude one giving aid to the other, if that one's territory is attacked.
- If either the Romans or the Carthaginians stand in need of help, Carthage was to supply the ships, whether for transport or war, but each state was to pay for its own men employed on the ships.
- The Carthaginians were to give aid by sea to the Romans if need be; but no one was to compel the crews of the ships to disembark against their will.
Implications and aftermath
While each party to the treaty was not obliged to come to the aid of the other, it was an attempt by Carthage, which felt itself less able to carry out land warfare, to drag Rome into a land war in Sicily: the Carthaginians would supply ships for the transport of troops, and would pay the cost of supplies and cargo. The treaty also implied that Carthage was offering Rome the help of its navy against Pyrrhus, since Roman generals, such as Publius Cornelius Scipio, commonly used the sailors of its transport ships alongside the soldiers, in battle.
An improvement in Rome's condition followed soon after the treaty, which acknowledged its increased military and economic powers. The treaty, on the other hand, betrayed Carthage's relative weakness in conceding that Rome was an equal, which was probably a result of its difficulties in Sicily. It may also have been this treaty that led the Romans to understand their capacity for development, the importance and the power of the Republic, and the limits of the power of Carthage. Rome would subsequently defeat Pyrrhus, who by then had defeated the Carthaginians, and needed only to extend its reach to conquer rich Sicily, with its grain reserves.
In 275 BC, after the defeat of Maleventum (Beneventum), Pyrrhus returned Epirus and Rome was left master of the entire Italian peninsula south of the Tusco-Emilian Apennines. Rome was also left in close contact with Greek culture, near-mastery of shipbuilding and management, and aware of the power of its legions and of the possibility of expansion.
The First Punic war began fifteen years later, in 264 BC.
