Demetrius, who had been unsuccessful against Ptolemy and against the Nabataeans, liberates Athens from Cassander in 307 BCE, ousting Demetrius of Phaleron, Cassander's governor, and reestablishing the old Athenian constitution.

The grateful Athenians honor Antigonus and Demetrius as divine saviors (theoi soteres).

Cassander's influence in Greece is now broken.

Segesta, whose population is a Helllenized mixed of Elymians and Ionian Greeks, has remained an ally of Carthage.

Besieged by Dionysius of Syracuse in 397 BCE, it is destroyed by Agathocles of Syracuse in 307 BCE, but will recover.

The tyrant Agathocles had returned from his invasion of Africa in 308 to break the Carthaginian blockade of Syracuse; in his absence, the Carthaginians in Africa defeat his remaining forces in 307.

Demetrius defeats Ptolemy's fleet near Salamis on Cyprus in 306, and conquers the island.

Demetrius' victory over Ptolemy gives Antigonus control of the Aegean, of the eastern Mediterranean, and of all of the Near East except Babylonia.

The assembled army proclaims Antigonus king (basileus), and his friends adorn him with the diadem.

For his part, Antigonus appoints Demetrius king and co-regent and sends him the diadem.

This is to become a traditional ceremony in the Hellenistic monarchy.

An exceptional strategist and combat leader, Antigonus is also an astute ruler who cultivates the friendship of Athens and other Greek city-states.

He establishes as his capital city Antigoneia, a little father up on the Orontes than present-day Antakya (Antioch).

Ptolemy temporarily loses Cyrene as well and is unable to hold the important Greek positions of Corinth, …

…Sicyon and …

…Megara.

The Athenian-born parents of the philosopher Epicurus, Neocles and Chaerestrate, his father a citizen, had emigrated to the Athenian settlement on the Aegean island of Samos about ten years before Epicurus's birth in February 341 BCE.

As a boy, he had studied philosophy for four years under the Platonist teacher Pamphilus.

He had gone to Athens at the age of eighteen for his two-year term of military service.

The playwright Menander had served in the same age-class of the ephebes as Epicurus.

After the death of Alexander the Great, Perdiccas had expelled the Athenian settlers on Samos to Colophon, on the coast of what is now Turkey.

Epicurus had joined his family there after the completion of his military service.

He had studied under Nausiphanes, who follows the teachings of Democritus.

Epicurus taught in Mytilene in 311/310 but caused strife and was forced to leave.

He then founded a school in Lampsacus in 308 before returning in 306 to Athens, where he founds The Garden, a school named for the garden he owns about halfway between the Stoa and the Academy that serves as the school's meeting place.

His followers will come to be known as philosophers of the garden.

The school accepts women and enslaved people.

Agathocles, finally defeated by Carthage in 307 BCE, concludes a favorable peace the following year, which restricts Carthaginian power in Sicily to the area west of the Halycus (Platani) River.
