The History of Sparta describes the destiny of the ancient Dorian Greek state known as Sparta from its beginning in the legendary period to its incorporation into the Achaean League under the late Roman Republic, as Allied State, in 146 BC, a period of roughly 1000 years. Since the Dorians were not the first to settle the valley of the Eurotas River in the Peloponnesus of Greece, the preceding Mycenaean and Stone Age periods are described as well. Sparta went on to become a district of modern Greece. Brief mention is made of events in the post-classical periods.
Dorian Sparta rose to dominance in the 6th century BC. At the time of the Persian Wars, it was the recognized leader by assent of the Greek city-states. It subsequently lost that assent through suspicion that the Athenians were plotting to break up the Spartan state after an earthquake destroyed Sparta in 464 BC. When Sparta defeated Athens in the Peloponnesian War, it secured an unrivaled hegemony over southern Greece.[1] Sparta's supremacy was broken following the Battle of Leuctra in 371 BC.[1] It was never able to regain its military supremacy[2] and was finally absorbed by the Achaean League in the 2nd century BC.
