Homosexuality in the militaries of ancient Greece was a significant aspect across the ancient Greek city-states, ranging from being a core part of military life to being an accepted practice of some individual soldiers. It was regarded as contributing to morale.[1] Although the primary example is the Sacred Band of Thebes, a unit said to have been formed of same-sex couples, the Spartan tradition of military heroism has also been explained in light of strong emotional bonds resulting from homosexual relationships.[2] Various ancient Greek sources record incidents of courage in battle and interpret them as motivated by homoerotic bonds.
