Rothbard could have been acclaimed for just his works in history, without all his contributions to economics. The Panic of 1819, America's Great Depression, Conceived In Liberty, History of Economic Thought, and A History of Money and Banking are each structured upon Rothbard's theory of power and liberty.
Rothbard sees the liberty of the individual (social power) as the fountainhead of all human glories in opposition to state power. History cannot be imagined without theory. Historians need to understand economics.
