'The Hellenic World' is a term which refers to that period of ancient Greek history between 507 BCE (the date of the first democracy in Athens) and 323 BCE (the death of Alexander the Great). This period is also referred to as the age of Classical Greece and should not be confused with The Hellenistic World which designates the period between the death of Alexander and Rome's conquest of Greece (323 - 146 - 31 BCE). The Hellenic World of ancient Greece consisted of the Greek mainland, Crete, the islands of the Greek archipelago, and the coast of Asia Minor primarily (though mention is made of cities within the interior of Asia Minor and, of course, the colonies in southern Italy). This is the time of the great Golden Age of Greece and, in the popular imagination, resonates as 'ancient Greece'.
The great law-giver, Solon, having served wisely as Archon of Athens for 22 years, retired from public life and saw the city, almost immediately, fall under the dictatorship of Peisistratus. Though a dictator, Peisistratus understood the wisdom of Solon, carried on his policies and, after his death, his son Hippias continued in this tradition (though still maintaining a dictatorship which favored the aristocracy). After the assassination of his younger brother (inspired, according to Thucydides, by a love affair gone wrong and not, as later thought, politically motivated), however, Hippias became wary of the people of Athens, instituted a rule of terror, and was finally overthrown by the army under Kleomenes I of Sparta and Cleisthenes of Athens. Cleisthenes reformed the constitution of Athens and established democracy in the city in 507 BCE. He also followed Solon's lead but instituted new laws which decreased the power of the artistocracy, increased the prestige of the common people, and attempted to join the separate tribes of the mountan, the plain, and the shore into one unified people under a new form of government. According to the historian Durant, "The Athenians themselves were exhilarated by this adventure into sovereignty. From that moment they knew the zest of freedom in action, speech, and thought; and from that moment they began to lead all Greece in literature and art, even in statesmanship and war" (126). This foundation of democracy, of a free state comprised of men who "owned the soil that they tilled and who ruled the state that governed them", stabilized Athens and provided the groundwork for the Golden Age.
The list of thinkers, writers, doctors, artists, scientists, statesmen, and warriors of the Hellenic World comprises those who made some of the most important contributions to western civilization: The statesman Solon, the poets Pindar and Sappho, the playwrights Sophocles, Euripedes, Aeschylus and Aristophanes, the orator Lysias, the historians Herodotus and Thucydides, the philosophers Zeno of Elea, Protagoras of Abdera, Empedocles of Acragas, Heraclitus, Xenophanes, Socrates, Plato, and Aristotle, the writer and general Xenophon, the physician Hippocrates, the sculptor Phidias, the statesman Pericles, the generals Alcibiades and Themistocles, among many other notable names, all lived during this period. The Golden Age of Greece, according to the poet Shelley, "is undoubtedly...the most memorable in the history of the world" for the accomplishments and advancements made by the people of that time. Interestingly, Herodotus considered his own age as lacking in many ways and looked back to a more ancient past for a paradigm of a true greatness. The writer Hesiod, an 8th century BCE contemporary of Homer, claimed precisely the same thing about the age Herodotus looked back toward and called his own age "wicked, depraved and dissolute" and hoped the future would produce a better breed of man for Greece. Herodotus aside, however, it is generally understood that the Hellenic World was a time of incredible human achievement.
Major city-states (and sacred places of pilgrimage) in the Hellenic World were Argos, Athens, Eleusis, Corinth, Delphi, Ithaca, Olympia, Sparta, Thebes, Thrace, and, of course, Mount Olympus, the home of the gods. The gods played an important part in the lives of the people of the Hellenic World; so much so that one could face the death penalty for questioning - or even allegedly questioning - their existence, as in the case of Protagoras, Socrates, and Alcibiades (the Athenian statesman Critias, sometimes referred to as `the first atheist', only escaped being condemned because he was so powerful at the time). Great works of art and beautiful temples were created for the worship and praise of the various gods and goddesses of the Greeks, such as the Parthenon of Athens, dedicated to the goddess Athena Parthenos (Athena the Virgin) and the Temple of Zeus at Olympia (both works which Phidias contributed to and one, the Temple of Zeus, listed as an Ancient Wonder). The temple of Demeter at Eleusis was the site of the famous Eleusinian Mysteries, considered the most important rite in ancient Greece. In his works The Iliad and The Odyssey, immensely popular and influential in the Hellenic World, Homer depicted the gods and goddesses as being intimately involved in the lives of the people, and the deities were regularly consulted in domestic matters as well as affairs of state. The famous Oracle at Delphi was considered so important at the time that people from all over the known world would come to Greece to ask advice or favors from the god, and it was considered vital to consult with the supernatural forces before embarking on any military campaign.
Among the famous battles of the Hellenic World that the gods were consulted on were the Battle of Marathon (490 BCE) the Battles of Thermopylae and Salamis (480 BCE), Plataea (479 BCE,) and The Battle of Chaeronea (338 BCE) where the forces of the Macedonian King Philip II commanded, in part, by his son Alexander, defeated the Greek forces and unified the Greek city-states. After Philip's death, Alexander would go on to conquer the world of his day, becoming Alexander the Great. Through his campaigns he would bring Greek culture, language, and civilization to to the world and, after his death, would leave the legacy which came to be known as the Hellenistic World.
