does anyone know of any available books that discuss the history of private courts? im interested in how analogues to the ancap system of law have historically operated.
Might be a start.
Starting at p. 286 of For a New Liberty, Rothbard talks about the libertarian aspects of medieval Ireland. Also:
The Not So Wild, Wild West
The Decline and Fall of Private Law in Iceland
Also, this post may have more links.
Hope this helps!
