The Battle of Mantinea took place in 362 BC in ancient Greece, marking a significant conflict during the period of the Greek city-states. It was fought between the forces of Thebes, led by the general Epaminondas, and a coalition of other city-states, including Sparta, Athens, and Argos. The battle was notable for its innovative tactics and the use of the Theban Sacred Band, an elite military unit. Despite the tactical brilliance of Epaminondas, the battle ended inconclusively, with heavy casualties on both sides. The death of Epaminondas during the conflict marked a turning point, leading to a decline in Theban power and the eventual rise of Macedonia under Philip II. The battle is often remembered for its impact on the shifting alliances and power dynamics in ancient Greece.
