Murray Rothbard was an economist of the Austrian School[fn:1] who helped found the Libertarian Party in the 1970s. As far as I can tell, Rothbard was not a Christian. Nevertheless, his knowledge of history and sharp mind lead to a brief, but insightful review of the history of millennialism in the modern era and explanation for the political programs of (mostly) American Evangelicals and "fundamentalists". What drove Rothbard to write the article was his concern as a Libertarian[fn:[[#2]]] about the political programs of post-millenialists who believe the Kingdom of God must be established on Earth before the Jesus Christ will return.
Rothbard's brief article is no substitute for a nuanced history of Christian Millennialism but it is worth reading. It's valuable both as an overview and an aid in understanding the suspicion many non-Christians, particularly those who believe individual rights are the foundation to all human society, view Christian politics.
