Thebes is a city in Central Greece in Boeotia. Today, about 23,000 people live there. It lies on the border of Boeotia and Attica. Archaeologists have found a Mycenaean settlement. They have also found clay tablets written in Linear B script. Thebes was once a super-power in Greece until the rise of Macedonia. It became a dominant power after their victory over the Spartans at the Battle of Leuctra in 371 BC.
