Pericles was a Greek statesman and general during the Golden Age of Athens. He was prominent and influential in Ancient Athenian politics, particularly between the Greco-Persian Wars and the Peloponnesian War, and was acclaimed by Thucydides, a contemporary historian, as "the first citizen of Athens". Pericles turned the Delian League into an Athenian empire and led his countrymen during the first two years of the Peloponnesian War.
