| Organised by | Alcibiades |
| Outcome | Overthrow of the democratic government of ancient Athens and replacement with a short-lived oligarchy known as the Four Hundred |
In the wake of the financial crisis caused by the failed Sicilian Expedition of the Athenian military in 413 BC, some high-status Athenian men, who had disliked the broad-based democracy of the city-state for a long time, sought to establish an oligarchy of the elite. They believed that they could manage foreign, fiscal, and war policies better than the existing government.
The movement toward oligarchy was led by a number of prominent and wealthy Athenians, who held positions of power in the Athenian army at Samos in coordination with Alcibiades.
