Ancient Greece

The collapse of the Mycenean civilization ushered in the Greek Dark Ages, from which written records are absent. The end of the Dark Ages is traditionally dated to 776 BC, the year of the first Olympic Games. The Iliad and the Odyssey, the foundational texts of Western literature, are believed to have been composed by Homer in the 7th or 8th centuries BC. Poetry shaped beliefs to the Olympian gods, but ancient Greek religion had no priestly class or systematic dogmas and encompassed other currents, such as popular cults, like that of Dionysus, mysteries and magic. At this time there emerged kingdoms and city-states across the Greek peninsula, which spread to the shores of the Black Sea, Magna Graecia in southern Italy and Asia Minor. These reached great prosperity that resulted in an unprecedented cultural boom, that of classical Greece, expressed in architecture, drama, science, mathematics and philosophy. In 508 BC, Cleisthenes instituted the world's first democratic system of government in Athens.

By 500 BC, the Persian Empire controlled the Greek city states in Asia Minor and Macedonia. Attempts by Greek city-states of Asia Minor to overthrow Persian rule failed, and Persia invaded the states of mainland Greece in 492 BC, but was forced to withdraw after defeat at the Battle of Marathon in 490 BC. In response, the Greek city-states formed the Hellenic League in 481 BC, led by Sparta, which was the first recorded union of Greek states since the mythical union of the Trojan War. The second Persian invasion of Greece was decisively defeated in 480 – 479 BC, at Salamis and Plataea, marking the eventual withdrawal of the Persians from all their European territories. The Greek victories in the Greco-Persian Wars are a pivotal moment in history, as the 50 years of peace afterwards are known as the Golden Age of Athens, a seminal period that laid many foundations of Western civilization. Lack of political unity resulted in frequent conflict between Greek states. The most devastating intra-Greek war was the Peloponnesian War (431–404 BC), which marked the demise of the Athenian Empire and the emergence of Spartan and later Theban hegemony. Weakened by constant wars among them during the 4th century BC, the Greek poleis were subjugated to the rising power of the kingdom of Macedon under king Philip II into an alliance known as the Hellenic League.

After Philip's assassination in 336 BC, his son and king of Macedon, Alexander, set himself leader of a Panhellenic campaign against the Persian Empire and abolished it. Undefeated in battle, he marched, until his untimely death in 323 BC, to the banks of the Indus. Alexander's empire fragmented, inaugurating the Hellenistic period. After fierce conflict amongst themselves, the generals that succeeded Alexander and their successors founded large personal kingdoms in the areas he had conquered, such as that of the Ptolemies in Egypt and of the Seleucids in Syria, Mesopotamia and Iran. The newly founded poleis of these kingdoms, such as Alexandria and Antioch, were settled by Greeks as members of a ruling minority. As a result, during the centuries that followed a vernacular form of Greek, known as koine, and Greek culture was spread, while the Greeks adopted Eastern deities and cults. Greek science, technology, and mathematics reached their peak during the Hellenistic period. Aspiring to maintain their autonomy and independence from the Antigonid kings of the Macedonians, many poleis of Greece united in koina or sympoliteiai i.e. federations, while after the establishment of economic relations with the East, a stratum of wealthy euergetai dominated their internal life.
