Sacred Band of Thebes

The Sacred Band of Thebes was an elite military unit of 150 male couples, 300 soldiers in total, formed in the early 4th century BCE in the city-state of Thebes. The unit's premise: soldiers fighting beside their lovers are more courageous than soldiers fighting for abstractions. The Sacred Band defeated Sparta, the dominant military power of the era, at the Battle of Leuctra in 371 BCE, ending Spartan supremacy. It was annihilated at Chaeronea in 338 BCE by Philip II of Macedon and the young Alexander.

The Sacred Band was formed by the Theban general Gorgidas around 378 BCE, building on an idea attributed to Plato in the Symposium: that an army of lovers would be unbeatable, because no man would commit a shameful act before his beloved or desert him in danger. Epaminondas and Pelopidas restructured it into a unified tactical unit rather than dispersing it throughout the army.

At the Battle of Leuctra (371 BCE), the Sacred Band was the decisive instrument of a stunning upset. Sparta had been the dominant land power in Greece for generations. Epaminondas's oblique order concentrated his best troops on the left flank against the Spartan elite, and the Sacred Band's refusal to break under the Spartan assault determined the battle. 400 Spartiate citizens died at Leuctra, which was nearly catastrophic for a city whose citizenship numbered only a few thousand. Spartan dominance never recovered.

The Sacred Band was destroyed as a unit at the Battle of Chaeronea (338 BCE), where Philip II of Macedon used his son Alexander (later 'the Great') to cut through the Theban line. When Philip surveyed the dead afterward and found the 300 bodies of the Sacred Band lying where they fell, each killed facing the enemy, he reportedly wept and said: 'Perish any man who suspects that these men either did or suffered anything that was base.' Predictive History uses the Sacred Band to illustrate the power of bonds formed through transgression, the shared crossing of social norms creates cohesion that no amount of ordinary training can replicate.
