The Athenians never had an empire as such. The Athenian city-state was over run and incorporated into the Greek Empire by Philip of Macedon, Alexander the great's father.
"The Greeks likewise assembled their largest army since the Persian invasion to face the Macedonian invasion. At Chaeronea in central Greece where the two armies met, the whole of Greece put 35,000 infantry and 2,000 cavalry on the field, while the Macedonians had 30,000 infantry and 2,000 cavalry. Although outnumbered, with suburb[sic] tactics and well coordination of the phalanx with the cavalry, the Macedonian 'barbarian' defeated the united Greek army. Among the Greeks, the Athenians, Thebans, and the Achaeans suffered the biggest losses.
The ancient Roman and Greek historians, consider the battle of Chaeronea, on August 2nd, 338 BC as an end to Greek liberty and history." -
