Maybe after a significant period akin to the dark ages.
Liberty usually only occurs, when the people fell free from reprisals or such.
The resulting "slugfest" would have to evolve back into some semblance of society based on freedoms first.
Liberty died long before the Dark Ages, because the citizens of the Roman Empire were obviously not free. I think it would be interesting what the world would be like if the Minoan civilization of Crete, which existed before Greece, hadn't been destroyed by the undersea volcanic eruption.
