In the chapter on Statism: Our Condition of the 1983 version of the New Libertarian Manifesto by Samuel Edward Konkin III the following can be found,
In the 20th Century alone, war has murdered more than all previous deaths; taxes and inflation have stolen more than all wealth previously produced; and the political lies, propaganda, and above all, "Education" have twisted more minds than all the superstition prior; yet through all the deliberate confusion and obfuscation, the thread of reason has developed fibers of resistance to be woven into the rope of execution for the State: Libertarianism.
Being in the first 10 sentence in the seminal work on Agorism such a claim is kind of concerning. I don't see how it could be true.
Especially interesting is that he wrote this in 1983, the 20th century wasn't even over yet.
