Archaeological excavations in and around Thebes have revealed cist graves dated to Mycenaean times containing weapons, ivory, and tablets written in Linear B. These clay tablets bear names like te-qa-i, understood to be read as *T'hēg'wai's, meaning at Thebes. This script confirms the site was one of the first Greek communities drawn together within a fortified city. Richard Hope Simpson noted that the decline of Thebes after the end of the LH IIIB period recalls the Hypothebai or sub-Thebes of the Homeric Catalogue of the Ships. The central area known as the Cadmea shows signs of destruction towards the end of the Mycenaean era. Much of the site was abandoned during this time. Yet the Homeric Hypothebai may have been the seed of the Archaic and Classical polity when the city was reestablished in earnest.
Classical Military Hegemony
Theban forces under the command of Epaminondas ended Spartan hegemony at the Battle of Leuctra in 371 BC. An elite military unit called the Sacred Band of Thebes, composed of male lovers, proved instrumental in that victory. The great citadel of Cadmea served as a base of resistance when Athenians overran and occupied the rest of Boeotia between 457 and 447 BC. In 424 BC, at the head of the Boeotian levy, they inflicted a severe defeat on an invading force of Athenians at the Battle of Delium. Years of desultory fighting culminated in 371 BC with a remarkable victory over the Spartans at Leuctra. The winners were hailed throughout Greece as champions of the oppressed. They carried their arms into Peloponnesus and permanently crippled the power of Sparta by freeing many helot slaves. Philip II of Macedon brought decisive victory to his alliance against Thebes and Athens at Chaeronea in 338 BC. An unsuccessful revolt in 335 BC against Alexander the Great resulted in the destruction of the city.
