349 BCE

After recovering from illness, Philip II of Macedon turns his attention to the remaining Athenian controlled cities in Macedonia and to the city of Olynthus, in particular. The Athenians organize to send help. Sidon is besieged by Persian forces. The Persian Empire reasserted its dominance over Egypt after Nectanebo II was forced to flee following the Persian military campaign under Artaxerxes III. The native Egyptian rule briefly came to an end, and the Persians regained control. This was just a precursor to the later events that would lead to Alexander the Great's conquest of Egypt in the early 4th century BCE, ultimately ending Persian rule and ushering in the Hellenistic period.
