Anarchist Athens
LRC is"reprinting" two of my articles on the libertarian aspects of ancient Athens: The Athenian Constitution: Government by Jury and Referendum and Civil Society in Ancient Greece: The Case of Athens. (For the original versions see here and here.)
The articles were written in 1996 and 1998, respectively, and my thinking has undergone various sorts of evolution since, so I'm not prepared to stand by everything I said in them; but I certainly still endorse their central thesis: Contrary to the claims of so many historians, ancient Athens was neither a majoritarian, mob-rule democracy nor an organic, communitarian collective; instead, it was in many respects a quasi-anarchistic free-market constitutional republic -- and thus, like medieval Iceland, a valuable model for our libertarian future.
In addition to the sources cited in the articles, today I would recommend M. H. Hansen's wonderful book Polis and City-State: An Ancient Concept and Its Modern Equivalent, a devastating critique of modern-day mythology about the polis.
