Antipater in the context of "Seleucus I Nicator"

The Lamian War or the Hellenic War (323–322 BC), was an unsuccessful attempt by Athens and a large coalition of Greek states to end the hegemony of Macedonia over Greece just after the death of Alexander the Great. It was the last time Athens played a significant role as an independent power.

War was simmering in Greece after Alexander the Great issued the Exiles' Decree (in 324 BC), which ordered the Greek states to return all the people they had forced into exile. This decree meant that Athens had to surrender the island of Samos, colonised by Athenian clerurchs since 365 BC, while the Aetolian League had to leave Oiniadai, taken c.330 BC. Once the death of Alexander became known in June 323 BC, most states in mainland Greece revolted and founded the Hellenic League, recalling the alliance forged during the Persian Wars; this time with Macedonia in the role of the foreign invader. The Greeks were initially successful under their Athenian commander in chief Leosthenes, who managed to besiege Antipater, the Macedonian general in Europe, in the city of Lamia, which gave its name to the war. At this point however, the arrival of a large Macedonian fleet commanded by Cleitus the White from the Levant turned the tide in favour of Macedonia. Even though Athens had more ships than Macedonia, it did not have enough crews to man them all and its overextended navy was defeated off the Echinades island and Amorgos.

The Antipatrid dynasty (/ænˈtɪpətrɪd/; Ancient Greek: Ἀντιπατρίδαι) was a Dorian Greek dynasty of the ancient Greek kingdom of Macedon founded by Cassander, the son of Antipater, who declared himself King of Macedon in 305 BC. This dynasty did not last long; in 294 BC it was swiftly overthrown by the Antigonid dynasty.

Antigonus I Monophthalmus (Ancient Greek: Ἀντίγονος Μονόφθαλμος Antigonos Monophthalmos, "Antigonus the One-Eyed"; 382 – 301 BC) was a Macedonian Greek general and successor of Alexander the Great. A prominent military leader in Alexander's army, he went on to control large parts of Alexander's former empire. He assumed the title of basileus (king) in 306 BC and reigned until his death. He was the founder of the Antigonid dynasty, which ruled over Macedonia until its conquest by the Roman Republic in 168 BC.

Antigonus likely served under Philip II of Macedon. He took part in Alexander's invasion of Achaemenid Persia and was named satrap of Phrygia. After Alexander's death in 323 BC, he also received Pamphylia and Lycia in accordance with the Partition of Babylon. However, he later incurred the enmity of Perdiccas, the regent of Alexander's empire, and was driven from Phrygia. He fled to Greece and formed an alliance with Antipater, later joined by Ptolemy, against Perdiccas. Perdiccas was murdered by his own officers in 320 BC, and Antipater was elected the new regent. During a series of wars between Alexander's successors, Antigonus briefly emerged as the most powerful of the Diadochi, ruling over Greece, Asia Minor, Syria, Phoenicia and northern Mesopotamia. Cassander, Seleucus, Ptolemy and Lysimachus formed a coalition against him, which culminated in his decisive defeat and death at the Battle of Ipsus in 301 BC. His kingdom was divided up by Lysimachus and Seleucus, but his son Demetrius survived and went on to seize control of Macedonia in 294 BC.

Cassander (/kəˈsændər/; Ancient Greek: Κάσσανδρος, romanized: Kássandros; c. 355 BC – 297 BC) was king of the Ancient Greek kingdom of Macedonia from 305 BC until 297 BC, and de facto ruler of southern Greece from 317 BC until his death.

A son of Antipater and a contemporary of Alexander the Great, Cassander was one of the Diadochi who warred over Alexander's empire following the latter's death in 323 BC. Cassander later seized power by having Alexander's son and heir Alexander IV murdered. While governing Macedonia from 317 BC until 297 BC, Cassander focused on strengthening the northern borders and economic development, while founding or restoring several cities (including Thessalonica, Cassandreia, and Thebes); however, his ruthlessness in dealing with political enemies complicates assessments of his rule.

Agis III (Greek: Ἄγις, died 331 BC) was the eldest son of Archidamus III, and the 21st Eurypontid king of Sparta between 338 and 331 BC. He tried to lead a revolt against Macedonian hegemony over Greece, but was defeated by Antipater—Alexander the Great's regent in Greece—at the Battle of Megalopolis in 331 BC, where he died.

The Battle of Megalopolis was fought in 331 BC between Spartan-led forces and Macedonia. Alexander's regent Antipater led the Macedonians to victory over King Agis III. Alexander, warring in Asia at the time, called it a "battle of mice" (Ancient Greek: μυομαχίᾱ), according to Plutarch.

Eumenes (/juːˈmɛniːz/; Ancient Greek: Εὐμένης; fl. 361–315 BC) was a Greek general, satrap, and Successor of Alexander the Great. He participated in the Wars of Alexander the Great, serving as Alexander's personal secretary and later on as a battlefield commander. Eumenes depicted himself as a lifelong loyalist of Alexander's dynasty and championed the cause of the Macedonian Argead royal house.

In the Wars of the Diadochi after Alexander's death, Eumenes initially supported the regent Perdiccas in the First Diadochi War, and later the Argead royalty in the Second Diadochi War. Despite less experience as a commander, Eumenes defeated Craterus, one of Alexander's most accomplished generals, at the Battle of the Hellespont in 321 BC. After Perdiccas' murder in 320 BC Eumenes became a public enemy of the new Post-Alexander regime under Antipater and Antigonus. In 319 BC he was defeated by Antigonus at the Battle of Orkynia and confined to Nora.
