Preparations

The Achaean League was upset that one of its members had remained under Spartan occupation and persuaded the Romans to revisit their decision to leave Sparta's territorial gains intact. The Romans agreed with the Achaeans, as they did not want a strong and re-organized Sparta causing trouble after the RomansThe Roman Republic was a form of government of Rome and the era of the classical Roman civilization when it was run through public representation of the Roman people. Beginning with the overthrow of the Roman Kingdom (traditionally dated to 509 BC) and ending in 27 BC with the establishment of the Roman Empire, Rome's control rapidly expanded during this period - from the city's immediate surroundings to hegemony over the entire Mediterranean world.Romans left Greece.

In 195 BC, Titus Quinctius Flamininus, the Roman commander in Greece, called a council of the Greek states at Corinth to discuss whether or not to declare war on Nabis. Among the states whose delegates participated were the Aetolian League, Macedon, Rome, Pergamum, Rhodes, Thessaly and the Achaean League. All the states represented favored war, except for the Aetolian League and Thessaly, both of which wanted the Romans to leave Greece immediately. These two states offered to deal with Nabis themselves, but they met opposition from the Achaean League, which objected to any possible growth in the Aetolian League's power. The modern historian Erich Gruen has suggested that the Romans may have used the war as an excuse to station a few legions in Greece in order to prevent the Spartans and the Aetolian League from joining the Seleucid King Antiochus III if he invaded Greece.

Flamininus first sent an envoy to Sparta, demanding that Nabis either surrender Argos to the Achaean League or face war with Rome and her Greek allies. Nabis refused to comply with Flamininus' ultimatum, so 40,000 Roman soldiers and their Greek allies advanced towards the Peloponnese. Entering the Peloponnese, Flamininus joined his force with that of the Achaean commander, Aristaenos, who had 10,000 infantry and 1,000 cavalry in Cleonae. Together, they advanced towards Argos.

Nabis had appointed his brother-in-law, the Argive Pythagoras, as commander of his garrison of 15,000 men in Argos. As the Romans and the Achaean League were advancing towards the city, a young Argive named Damocles attempted to stir up a revolution against the Spartan garrison. With a few followers, he stood in the city's agora and shouted to his fellow Argives, exhorting them to rise in revolt. However, no mass uprising materialized and Damocles and most of his followers were surrounded and killed by the Spartan garrison.

A few survivors from Damocles' group escaped from the city and went to Flamininus' camp. They suggested to Flamininus that, if he moved his camp closer to the city gates, the Argives would revolt against the Spartans.

The Roman commander sent his light infantry and cavalry to find a position for the new camp. Upon spotting the small group of Roman soldiers, a group of Spartan troops sallied forth from the gates and skirmished with the Romans about 300 paces from the city walls. The Romans forced the Spartans to retreat back into the city.

Flamininus moved his camp to the position where the skirmish had occurred. For a day he waited for the Spartans to attack him but, when no attack came, he called a war council to discuss whether or not to press the siege. All the Greek leaders except Aristaenos thought that they should attack the city, as capturing it was their primary objective in going to war. Aristaenos, on the other hand, argued that they should instead strike directly at Sparta and Laconia. Flamininus agreed with Aristaenos and the army marched to Tegea in Arcadia. The next day, Flamininus advanced to Caryae, where he waited for allied auxiliaries to reinforce him. These forces soon arrived and joined the Romans; they consisted of a contingent of Spartan exiles led by Agesipolis, the legitimate King of Sparta, who had been overthrown by the first Tyrant of Sparta, Lycurgus, twenty years earlier, and 1,500 Macedonians with 400 Thessalian cavalry sent by Philip. News also reached the allies that several fleets had arrived off the Laconian shore: a Roman fleet under Lucius Quinctius with forty ships; a Rhodian fleet with eighteen ships, led by Sosilas, hoping that the defeat of Nabis would stop the pirates that plagued their ships; and a Pergamene fleet of forty ships under King Eumenes II of Pergamum, who hoped to gain more favor with Rome and Roman support if Antiochus invaded.

  HISTORIC BATTLES

  Roman-Spartan War (195 BC)

  The War against Nabis, or the Laconian War, of 195 BC was fought between the Greek city-state of Sparta and a coalition composed of Rome, the Achaean League, Pergamum, Rhodes, and Macedon. As a result of the war, Sparta lost its position as a major power in Greece. Subsequent Spartan attempts to recover the losses failed and Nabis, the last sovereign ruler, was eventually murdered. View Historic Battle »

  Background: In 205 BC, Nabis signed a peace treaty with Rome, but in 201 BC he attacked the territory of Messene, at that time an ally of both parties, which Sparta had ruled until the mid 4th century BC.

  Nabis' reforms: Nabis' rule was largely based on his social reforms and the rebuilding of Sparta's armed forces.

  Preparations: The Achaean League was upset that one of its members had remained under Spartan occupation and persuaded the Romans to revisit their decision to leave Sparta's territorial gains intact.

  Laconian campaign: Nabis drafted 10,000 citizens into his army and hired 3,000 additional mercenaries.

  Siege of Sparta: The Spartans initially held out against the allies, but their resistance was hampered by the fact that the Romans' large shields made missile attacks futile.

  Aftermath: Even though Sparta was a landlocked and effectively powerless state, the Romans wanted an independent Sparta to act as a counterweight against the growing Achaean League.
