first civil war.
That was not Anarchy.
I'd be interested in what you would actually consider anarchy, then... Because the Icelandic commonwealth is one of the best historical examples, as is the Somali Xeer law system.
Anarchy is the non-patriarchal, non-monogamous, autark, selfsufficient, matrilineal community, which is not taxed and dominated by masters, rulers, strangers. That was human being until the neolithic revolution, and, at some few remaining territories, until today.
Most 'libertarian anarchists' believe in individualism as the opposite of collectivism. They are wrong. Individualism exists exclusively in collectivist (state) organisations of 'citizens'. The opposite of collectivism/individualism of the citizen is the human in the self sufficient community. A citizen is not a human, at best an undead cartoon of it, as I wrote already in another thread.
