Ancient Greek History: Archaic, Classical and Hellenistic Worlds
Greek city-states developed during the Archaic period, conventionally about 800–480 BC. Athens and Sparta later led competing coalitions through the Classical period. Philip II established Macedonian leadership after Chaeronea in 338 BC, and Alexander conquered the Achaemenid Persian Empire. Rival kingdoms emerged after his death in 323 BC and remained major powers until successive Roman annexations.
These developments followed the collapse of the Mycenaean palaces at the end of the Bronze Age. Political authority became more local, while revived exchange and alphabetic writing accompanied the growth of city-states. Overseas settlements extended Greek-speaking communities around the Mediterranean.

From post-palatial communities to the Archaic polis
By the eighth century BC, a polis joined a citizen community with an urban centre and surrounding territory. Shared laws and public cults helped organise membership. Local offices and assemblies exercised authority over that community. Mountains separated mainland valleys, while sea routes connected islands and coastal settlements. Cities maintained separate governments and dialects. Overseas foundations generally formed independent communities with continuing ties to their founding cities. The Archaic period is conventionally dated about 800–480 BC. City-states acquired written laws and monumental temples, and stamped coinage spread during the seventh and sixth centuries.
Athens illustrates one local sequence rather than a universal Greek model. The city developed written laws associated with Draco in the seventh century BCE, reforms attributed to Solon in 594 BCE, a tyranny established by Pisistratus in the sixth century, and further changes under Cleisthenes late in that century. These developments contributed to the later Athenian democracy, in which the assembly became the formal mechanism for decisions by citizens. Political rights remained restricted: women, slaves and resident foreigners did not possess the same rights as male citizens. Other poleis followed different paths. Sparta retained two hereditary kings, a council of elders and annually appointed ephors, or magistrates who helped supervise the political system.

Greek foundations spread across the Mediterranean and Black Sea between roughly 750 and 500 BC. Settlers sought land and trading opportunities amid political pressures at home. Some settlements formed independent poleis; emporia served mixed communities engaged in manufacture and exchange.
Greek communities adapted the Phoenician script into an alphabet, adding written vowels. Mediterranean exchange supplied artistic models and new products. Coinage introduced stamped pieces of recognised weight, while farming continued to supply most livelihoods.
Sparta followed a different path from Athens. Its citizen community depended on the labour of helots, a population held in hereditary subjection, and combined kingship with councils, ephors and an assembly. Messenian resistance and the maintenance of this unequal social order shaped Spartan military commitments. The origins and precise legal character of helot dependence remain debated.
Citizen infantry supplied much of its own equipment, with property affecting access to arms. Hoplites used a large shield and spear in close formation. Agricultural work constrained the time available for campaigning.

Classical Greece: City-states, alliances and Macedonian expansion
The Classical period is often associated with the conflicts between the Greek city-states and the Achaemenid Persian Empire, followed by rivalry among the leading Greek powers. In 499 BCE, Ionian cities under Persian rule rebelled, receiving support from Athens and Eretria. Persian reprisals helped produce the invasion defeated by the Athenians and their Plataean allies at Marathon in 490 BCE. A larger invasion under Xerxes was resisted by an alliance of Greek states, including Athens and Sparta. Persian forces were defeated at Salamis in 480 BCE and Plataea in 479 BCE, after which Greek campaigns gradually pushed Persian power away from much of the Aegean.
Athens led the Delian League, an alliance formed against Persia in 478/7 BC, and increasingly enforced its demands on members. Contributions supported a large fleet. Sparta maintained a separate coalition centred on land power in the Peloponnese, often called the Peloponnesian League; its disputes with Athens led to war in 431 BC.
Sparta invaded Attica while Athens used its fleet to attack elsewhere. The expedition to Sicily in 415–413 BC ended with the loss of Athenian forces at Syracuse. Sparta defeated the remaining fleet at Aegospotami in 405 BC; Athens surrendered in 404 BC and briefly came under the Thirty Tyrants.
Spartan dominance was also temporary. During the fourth century BCE, Athens, Sparta and Thebes each tried to lead Greek affairs, but none established lasting control over the mainland. Thebes defeated Sparta at Leuctra in 371 BCE and helped end Spartan control over Messenia. The battle of Mantinea in 362 BCE confirmed the instability of the balance, especially after the death of the Theban commander Epaminondas. Alliances such as the Athenian naval league also changed or collapsed. Repeated wars exhausted the major poleis and created conditions in which Macedon could intervene.
Macedon was a kingdom to the north of the central Greek city-states, with its own regional traditions and connections to the Greek world. Philip II used diplomacy, military force and shifting alliances to extend Macedonian influence. After defeating a Greek coalition at Chaeronea in 338 BCE, he organised many Greek states in the League of Corinth. The league prepared a campaign against Persia.
Alexander became king in 336 BC and crossed into Asia in 334 BC. Victories at Issus in 333 BC and Gaugamela in 331 BC defeated Darius III. Campaigns reached Bactria and India before Alexander died in Babylon in 323 BC.

The Hellenistic World: Kingdoms, cities and cultural exchange
The Hellenistic period conventionally begins with Alexander’s death in 323 BCE and ends around 30 BCE, when the Ptolemaic kingdom of Egypt was absorbed by Rome. Alexander left no settled succession capable of preserving his empire as one state. His former generals and their successors fought over territory, creating kingdoms ruled by dynasties such as the Antigonids in Macedon, the Ptolemies in Egypt and the Seleucids across Syria and much of the former Persian Empire. Other states included the Attalids in Anatolia, the kingdom of Epirus and the Greco-Bactrian kingdom.
Royal courts controlled armies and revenue across territories formerly governed by the Achaemenids. Antigonus I was killed at Ipsus in 301 BC by a coalition of rival rulers. The Seleucid kingdom later lost eastern territories to new powers, including the Parthians. Royal foundations such as Alexandria and Antioch brought settlers into new urban centres. Cities maintained magistrates and assemblies while negotiating with kings. Greek became widely used in administration and education alongside local languages.
The Aetolian and Achaean Leagues joined city-states under federal authorities for diplomacy and military action. Individual communities retained local government within those alliances.
The Ptolemies funded scholarship at Alexandria, where collections and textual comparison supported research. Hellenistic scholars developed geometry and geographical measurement. Royal patronage and movement between cities supported their work.
Roman intervention gradually reduced the independence of the Hellenistic kingdoms and leagues. Macedon was absorbed after repeated wars, and the Achaean and Aetolian political systems were eventually defeated. The Seleucid kingdom survived in reduced form until 64 BCE, while the Ptolemaic kingdom continued in Egypt until 30 BCE.
