The Battle of Leuctra (or Leuktra) was a battle fought on July 6, 371 BC, between the Boeotians led by Thebans and the Spartans along with their allies amidst the post-Corinthian War conflict. The battle took place in the neighbourhood of Leuctra, a village in Boeotia in the territory of Thespiae. Theban victory shattered Sparta’s immense influence over the Greek peninsula which Sparta had gained since its victory in the Peloponnesian War.
