[2] Referring to Sparta as having a "wall of men, instead of bricks," he proposed reforming the Spartan society to develop a military-focused lifestyle following "proper virtues" such as equality for the male citizens, austerity, strength, and fitness.
Spartan boys deemed strong enough entered the agoge regime at the age of seven, undergoing intense and rigorous military training.
[3] Their education focused primarily on fostering cunningness, practicing sports and war tactics, and also included learning about poetry, music, academics, and sometimes politics.
In a battle, each opposing army would try to fight through the other line on the right (strong or deep) side and then turn left; wherefore they would be able to attack the vulnerable flank.
[citation needed] War chariots were used by the elite, but unlike their counterparts in the Middle East, they appear to have been used for transport, with the warrior dismounting to fight on foot and then remounting to withdraw from combat.
Later traditions ascribed the reforms to the possibly mythical figure of Lycurgus, who created new institutions and established the Spartan state's military nature.
The Spartans forced Arcadia into recognizing their power; Argos lost Cynuria (the South Eastern coast of the Peloponnese) in about 546 and suffered a further crippling blow from Cleomenes I at the Battle of Sepeia in 494.
[8] By the early 5th century, Sparta was the unchallenged master in southern Greece, as the leading power (hegemon) of the newly established Peloponnesian League (which was more characteristically known to its contemporaries as "the Lacedaemonians and their allies").
King Croesus of Lydia established an alliance with the Spartans,[10] and later, the Greek cities of Asia Minor appealed to them for help during the Ionian Revolt.
Sparta suffered several defeats during these wars, including, for the first time, the surrender of an entire Spartan unit at Sphacteria in 425 BC.
Under its admiral Lysander, the Persian-funded Peloponnesian fleet captured the Athenian alliance cities, and a decisive naval victory at Aegospotami forced Athens to capitulate.
By the end of the 5th century BC, Sparta had suffered severe casualties in the Peloponnesian Wars, and its conservative and narrow mentality alienated many of its former allies.
The ensuing Corinthian War led to the humiliating Peace of Antalcidas that destroyed Sparta's reputation as the protector of Greek city-states' independence.
At the same time, Spartan military prestige suffered a severe blow when a mora of 600 men was defeated by peltasts (light infantry) under the command of the Athenian general Iphicrates.
[1] To a large degree, in order to keep the vastly more numerous helots subdued, it would require the constant war footing of the Spartan society.
[18] By the end of the Peloponnesian War, the structure of the army had evolved further, to address the shortages in manpower and create a more flexible system which allowed the Spartans to send smaller detachments on campaigns or garrisons outside their homeland.
In addition, they were taught to read and write and learned the songs of Tyrtaios, that celebrated Spartan exploits in the Second Messenian War.
Military duty lasted until the 60th year, but there are recorded cases of older people participating in campaigns in times of crisis.
The Spartans themselves did not introduce any significant changes or tactical innovations in hoplite warfare, but their constant drill and superb discipline made their phalanx much more cohesive and effective.
[32][33] The army proceeding was led by the king, with the skiritai and cavalry detachments acting as an advance guard and scouting parties.
[34] The necessary provisions (barley, cheese, onions and salted meat) were carried along with the army, and a helot manservant accompanied each Spartan.
[36] The army gave sacrifice every morning as well as before battle by the king and the officers; if the omens were not favourable, a pious leader might refuse to march or engage with the enemy.
[43] During the Archaic period, Spartans were armored with flanged bronze cuirasses, leg greaves, and a helmet, often of the Corinthian type.
During the later 5th century BC, when warfare had become more flexible, and full-scale phalanx confrontations became rarer, the Greeks abandoned most forms of body armor.
The Lacedaemonians also adopted a new tunic, the exōmis, which could be arranged to leave the right arm and shoulder uncovered and free for action in combats.
[47] In battles, the Spartans told stories of valor to inspire the troops and, before a major confrontation, they sang soft songs to calm the nerves.
With Persian gold, Lysander, appointed navarch in 407 BC, was able to master a strong navy and successfully challenged and destroyed Athenian predominance in the Aegean Sea.
In the Battle of Cnidus of 394 BC, the Spartan navy was decisively defeated by a joint Athenian-Persian fleet, marking the end of Sparta's brief naval supremacy.
The last revival of the Spartan naval power was under Nabis, who created a fleet to control the Laconian coastline with aid from his Cretan allies.
This position was seemingly independent of the one-year term clause because it was used in 405 BC to give Lysander command of the fleet after he was already an admiral for a couple years.
