Socii - External Relations of Early Rome

External Relations of Early Rome

Because of the poverty of the sources, only the bare outline of Rome's external relations in the early period can be reliably discerned. It appears likely that Rome in the period 550-500, conventionally known as the period it was ruled by the Tarquin dynasty, established its hegemony over its Latin neighbours. The fall of the Roman monarchy was followed by a war with the Latins, who probably took advantage of the political turmoil in Rome to attempt to regain their independence. This war was brought to an end in 493 BC by the conclusion of the a treaty called foedus Cassianum, which lay the foundations for the Roman military alliance. According to the sources, this was a bilateral treaty between the Romans and the Latins. It provided for a perpetual peace between the two parties; a defensive alliance by which the parties pledged mutual assistance in case of attack; a promise not to aid or allow passage to each other's enemies; the equal division of spoils of war (half to Rome, half to the other Latins) and provisions to regulate trade between the parties. In addition the treaty may have provided for the Latin armed forces levied under the treaty to be led by a Roman commander. These terms served as the basic template for Rome's treaties with all the other Italian socii acquired over the succeeding two centuries.

As we do not know the nature of the Tarquinian hegemony over the Latins, we cannot tell how the terms of the Cassian treaty differed from those imposed by the Tarquins. But it is likely that Tarquin rule was more onerous, involving the payment of tribute, while the Republican terms simply involved a military alliance. The impetus to form such an alliance was probably provided by the acute insecurity caused by a phase of migration and invasion of the lowland areas by Italic mountain tribes in the period after 500 BC. The Sabines, Aequi and Volsci neighbours of Latium assailed the Latins, the Samnites invaded and subjugated the Greco-Etruscan cities of Campania, while the Messapii, Lucani and Bruttii in the South attacked the Greek coastal cities, crippling Tarentum and reducing the independent Greek cities on the Tyrrhenian coast to just Neapolis and Velia.

The new Romano-Latin military alliance proved strong enough to repel the incursions of the Italic mountain tribes, but it was a very tough struggle. Intermittent wars, with mixed fortunes, continued until c. 395 BC. The Sabines disappear from the record in 449 BC (presumably subjugated by the Romans), while campaigns against the Aequi and Volsci seem to have reached a turning point with the major Roman victory on Mount Algidus in 431 BC. In the same period, the Romans fought three wars against their nearest neighbouring Etruscan city-state, Veii, finally reducing the city in 396 BC. Although the annexation of Veii's territory probably increased the ager Romanus by c. 65%, this seems a modest gain for a century of warfare.

At this juncture, Rome was crushed by an invasion of central Italy by the Senones Gallic tribe. Routed at the river Allia in 386 BC, the Roman army fled to Veii, leaving their city at the mercy of the Gauls, who proceeded to ransack it and then demand a huge ransom in gold to leave. The effects of this disaster on Roman power are a matter of controversy between scholars. The ancient authors emphasize the catastrophic nature of the damage, claiming that it took a long time for Rome to recover. Cornell, however, argues that the ancients greatly exaggerated the effects and cites the lack of archaeological evidence for major destruction, the early resumption of an aggressive expansionist policy and the building of the "Servian" Wall as evidence that Rome recovered swiftly. The Wall, whose 11 km-circuit enclosed 427 hectares (an increase of 50% over the Tarquinian city) was a massive project which would have required an estimated five million man-hours to complete, implying plentiful financial and labour resources. Against this, Eckstein argues that the history of Rome in the 50 years subsequent to 386 BC appears a virtual replay of the previous century. There were wars against the same enemies except Veii (i.e. the Volsci, Aequi and Etruscans) in the same geographical area, and indeed against other Latin city-states such as Praeneste and Tibur, just 30 miles away. In addition, a treaty concluded with Carthage in c. 348 BC seems to describe Rome's sphere of control as much the same area as in a previous treaty signed in the first years of the Republic 150 years earlier: just Latium Vetus and not even all of that.
