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. The period during which he led Athens as its preeminent orator and statesman, roughly from 461 to 429 BC, is sometimes known as the "Age of Pericles", but the period thus denoted can include times as early as the Persian Wars or as late as the following century.
