Greek Civilization.

Ancient Greece is the civilization belonging to the period of Greek history lasting from the Archaic period of the 8th to 6th centuries BC to the end of antiquity and beginning of the Early Middle Ages with the rise of the Byzantine era following Justinian I.^[1] At the center of this time period is Classical Greece, which flourished during the 5th to 4th centuries BC, at first under Athenian leadership successfully repelling the military threat of Persian invasion. The Athenian Golden Age ends with the defeat of Athens at the hands of Sparta in the Peloponnesian War in 404 BC. Following the conquests of Alexander the Great, Hellenistic civilization flourished from Central Asia to the western end of the Mediterranean Sea.

The historical period of ancient Greece is unique in world history as the first period attested directly in proper historiography, while earlier ancient history or proto-history is known by much more circumstantial evidence, such as annals or king lists, and pragmatic epigraphy.

Herodotus is widely known as the "father of history", his Histories being eponymous of the entire field. Written between the 450s and 420s BC, the scope of Herodotus' work reaches about a century into the past, discussing 6th-century historical figures such as Darius I of Persia, Cambyses II and Psamtik III, and alludes to some 8th-century ones such as Candaules.

Herodotus was succeeded by authors such as Thucydides, Xenophon, Demosthenes, Plato and Aristotle. Most of these authors were either Athenians or pro-Athenians, which is why far more is known about the history and politics of Athens than of many other cities. Their scope is further limited by a focus on political, military and diplomatic history, ignoring economic and social history.^[6]
