The Hellenistic period began with the wars of the Diadochi, armed contests among the former generals of Alexander the Great to carve up his empire in Southeast Europe, West Asia, and North Africa. The wars lasted until 272 BC, witnessing the fall of both the Argead and Antipatrid dynasties of Macedonia in favor of the Antigonid dynasty. The era was also marked by successive wars between the Kingdom of Macedonia, the kingdom of Epirus, the Aetolian League, Achaean League, Sparta, Rhodes, kingdom of Pergamum as well as the Seleucid and Ptolemaic empires.

During the reign of Philip V of Macedon (r. 221–179 BC), the Macedonians not only lost the Cretan War (205–200 BC) to an alliance led by Rhodes, but their erstwhile alliance with Hannibal of Carthage also entangled them in the First and Second Macedonian War with ancient Rome. The perceived weakness of Macedonia in the aftermath of these conflicts encouraged Antiochus III the Great of the Seleucid Empire to invade mainland Greece, yet his defeat by the Romans at Thermopylae in 191 BC and Magnesia in 190 BC secured Rome's position as the leading military power in the region. Within roughly two decades after conquering Macedonia in 168 BC and Epirus in 167 BC, the Romans would eventually control the whole of Greece.

During the Hellenistic period the importance of Greece proper within the Greek-speaking world declined sharply. The great centers of Hellenistic culture were Alexandria and Antioch, capitals of Ptolemaic and Seleucid Kingdoms respectively. Cities such as Pergamon, Ephesus, Rhodes and Seleucia were also important, and increasing urbanisation of the Eastern Mediterranean was characteristic of the time.

Hellenistic kingdoms

The quests of Alexander had a number of consequences for the Greek city-states. It greatly widened the horizons of the Greeks, making the endless conflicts between the cities which had marked the 5th and 4th centuries BC seem petty and unimportant. It led to a steady emigration, particularly of the young and ambitious, to the new Greek empires in the east. Many Greeks migrated to Alexandria, Antioch and the many other new Hellenistic cities founded in Alexander's wake, as far away as what are now Afghanistan and Pakistan, where the Greco-Bactrian Kingdom and the Indo-Greek Kingdom survived until the end of the 1st century BC.

The defeat of the Greek city-states by Philip and Alexander also taught them that they could never again be powers in their own right, and that the hegemony of Macedon and its successor states could not be challenged unless the city states united, or at least federated. The Greeks valued their local independence too much to consider actual unification, but they made several attempts to form federations through which they could hope to reassert their independence.

Following Alexander's death a struggle for power broke out among his generals, which resulted in the break-up of his empire and the establishment of a number of new kingdoms. Macedon fell to Cassander, son of Alexander's leading general Antipater, who after several years of warfare made himself master of most of the rest of Greece. He founded a new Macedonian capital at Thessaloniki and was generally a constructive ruler.

Cassander's power was challenged by Antigonus, ruler of Anatolia, who promised the Greek cities that he would restore their freedom if they supported him. This led to successful revolts against Cassander's local rulers. In 307 BC, Antigonus's son Demetrius captured Athens and restored its democratic system, which had been suppressed by Alexander. But in 301 BC a coalition of Cassander and the other Hellenistic kings defeated Antigonus at the Battle of Ipsus, ending his challenge.

After Cassander's death in 298 BC, however, Demetrius seized the Macedonian throne and gained control of most of Greece. He was defeated by a second coalition of Greek rulers in 285 BC, and mastery of Greece passed to the king Lysimachus of Thrace. Lysimachus was in turn defeated and killed in 280 BC. The Macedonian throne then passed to Demetrius's son Antigonus II, who also defeated an invasion of the Greek lands by the Gauls, who at this time were living in the Balkans. The battle against the Gauls united the Antigonids of Macedon and the Seleucids of Asia, an alliance which was also directed against the wealthiest Hellenistic power, the Ptolemies of Egypt. The Epirote king Pyrrhus is known to have made Epirus a powerful state in the wider Hellenistic world (during 297–272 BC) that was comparable to the likes of Macedon and Ancient Rome. Pyrrhus' armies also attempted an assault against the state of Ancient Rome during their unsuccessful campaign in what is now modern-day Italy in 280-275 BC. Pyrrhus died in 272 BC leaving Antigonus Gonatas' Macedon the stronger power in Greece.

Antigonus II ruled until his death in 239 BC, and his family retained the Macedonian throne until it was abolished by the Romans in 146 BC. Their control over the Greek city states was intermittent, however, since other rulers, particularly the Ptolemies, subsidised anti-Macedonian parties in Greece to undermine the Antigonids' power. Antigonus placed a garrison at Corinth, the strategic centre of Greece, but Rhodes, Pergamum, Achaean League and Aetolian League and other Greek states retained substantial independence. Sparta also remained independent and generally refused to join any league.

In 267 BC, Ptolemy II persuaded the Greek cities to revolt against Antigonus, in what became the Chremonidean War, after the Athenian leader Chremonides. The cities were defeated and Athens lost her independence and her democratic institutions. The Aetolian League was restricted to the Peloponnese, but on being allowed to gain control of Thebes in 245 BC became a Macedonian ally. This marked the end of Athens as a political actor, although it remained the largest, wealthiest and most cultivated city in Greece. In 255 BC, Antigonus defeated the Ptolemaic fleet at Cos and brought the Aegean islands, except Rhodes, under his rule as well.
