Harry Elmer Barnes (1889–1968) was a pioneer of historical revisionism, meaning the use of historical scholarship to challenge and refute the narratives of history promulgated by the state and the political class, or as Barnes himself termed it, "court history." Long regarded as a progressive intellectual leader of the American Left, Barnes became associated with the Old Right for his opposition to the New Deal and to American entry into World War II. His work has had a profound influence on New Left historians such as William Appleman Williams and Gabriel Kolko, as well as on the historical writings of Murray Rothbard and other libertarians.

Ludwig von Mises: "Despots and democratic majorities are drunk with power. They must reluctantly admit that they are subject to the laws of nature. But they reject the very notion of economic law . . . economic history is a long record of government policies that failed because they were designed with a bold disregard for the laws of economics." - Austrian Economics: An Anthology
