The Sacred Band (Ancient Greek: , Hieròs Lókhos) was a troop of picked soldiers, consisting of 150 pairs of male lovers which formed the elite force of the Theban army in the 4th century BC. It is said to have been organised by the Theban commander Gorgidas in 378 BC and to have played a crucial role in the Battle of Leuctra. It was annihilated by Philip II of Macedon in the Battle of Chaeronea in 338 BC.
