Battle of Leuctra - Historical Significance

Historical Significance

The battle is of great significance in Greek history, and, by extension, European history.

The use of these tactics by Epaminondas was, perhaps, a direct result of the use of some similar maneuvers by Pagondas, his countryman, during the Battle of Delium. Further, Philip II of Macedon, who studied and lived in Thebes, was no doubt heavily influenced by the battle to develop his own, highly effective approach to tactics and armament. In turn, his son Alexander would go on to develop his father's theories to an entirely new level.

Historians Victor Davis Hanson and Donald Kagan have argued that Epaminondas's so-called "oblique formation" was not an intentional and preconceived innovation in infantry tactics, but was rather a clever response to circumstances. Because Epaminondas had stacked his left wing to a depth of fifty shields, the rest of his units were naturally left with far fewer troops than normal. This means that their maintenance of a depth of eight to twelve shields had to come at the expense of either number of companies or their width. Because Epaminondas was already outnumbered, he had no choice but to form fewer companies and march them diagonally toward the much longer Spartan line in order to engage as much of it as possible. Hanson and Kagan's argument is therefore that the tactic was more dilatory than anything else. Whatever its motivation, the fact remains that the tactic did represent an innovation and was undoubtedly highly effective.

The battle's political effects were far-reaching: the losses in material strength and prestige (prestige being an inestimably important factor in the Peloponnesian War) sustained by the Spartans at Leuctra and subsequently at the Battle of Mantinea were key in depriving them forever of their supremacy in Greece. Therefore, the battle permanently altered the Greek balance of power, as Sparta was deprived of her former prominence and was reduced to a second-rate power among the Greek city-states.

Theban supremacy in Greece was short-lived as it was subsequently lost to the Macedonians led by Philip II.
