Wars of the Diadochi
Athens and her allies revolted against Macedon upon hearing that Alexander had died, but were defeated within a year in the Lamian War. Meanwhile, a struggle for power broke out among Alexander's generals, which resulted in the break-up of his empire and the establishment of a number of new kingdoms (see the Wars of the Diadochi). Ptolemy was left with Egypt, Seleucus with the Levant, Mesopotamia, and points east. Control of Greece, Thrace, and Anatolia was contested, but by 298 BC the Antigonid dynasty had supplanted the Antipatrid.
