The Athenian democracy, in its two centuries of life-time, twice voted against its democratic constitution (both times during the crisis at the end of the Pelopponesian War of 431 to 404 BC), establishing first the Four Hundred (in 411 BCE) and second Sparta's puppet régime of the Thirty Tyrants (in 404 BCE). Both votes took place under manipulation and pressure, but democracy was recovered in less than a year in both cases. Reforms following the restoration of democracy after the overthrow of the Thirty Tyrants removed most law-making authority from the Assembly and placed it in randomly selected law-making juries known as "nomothetai". Athens restored its democratic constitution again after King Phillip II of Macedon (reigned 359-336 BCE) and later Alexander the Great (reigned 336–323 BCE) unified Greece, but it was politically over-shadowed by the Hellenistic empires. Finally, after the Roman conquest of Greece in 146 BC, Athens was restricted to matters of local administration.
