After defeating a coalition of Athens, Thebes, Persia, and other Greek city-states at the end of the Corinthian War in 387 BC, Sparta tyrannized all of Greece with nearly unchecked power. But her empire had been hollowed by the cost of generations of war and a most unfavourable trend in demographics: a sharp decline in Spartan soldiers and citizens. With Sparta's infirmity came a desperately tighter grip on Greece. And Sparta’s renowned king, Agesilaus II, held a special hatred for Thebes. After conquering the city in 382 BC, Sparta dismantled Thebes and intended to permanently eliminate their Theban problem. Thebes, though, was stubbornly resilient in the face of Sparta’s cruelty and not only survived Spartan occupation, but soon overthrew Sparta and aimed to shatter her empire. Against the odds, Thebes succeeded. Her victory boiled down to the indomitable spirit of two men: the irreproachable general Epaminondas and the cunning statesman Pelopidas. The two formed a local resistance movement that first liberated their home from Spartan oppression in 378 and then challenged Sparta’s empire outright in the Theban-Spartan War. By 371 at the Battle of Leuctra, their vision of a free Thebes and broken Sparta was realized, and the infamous Spartan war machine was at long last defeated. For the first time since the age of mythology, Thebes reigned supreme over Greece. Leuctra was the lynchpin of the new Theban Hegemony, and began a new era of empire in Greece, and the first power in centuries that was not Athens or Sparta.
