We have crossed the boundary that lies between Republic and Empire. If you ask when, the answer is that you cannot make a single stroke between day and night; the precise moment does not matter. There was no painted sign to say: “You now are entering Imperium.” Yet it was a very old road and the voice of history was saying: “Whether you know it or not, the act of crossing may be irreversible.”This article appeared in a 1966 issue of Left and Right, edited by Murray Rothbard, and is a condensed version of Garet Garrett’s pamphlet, The Rise of Empire, published in 1952, and included in his collection The People’s Pottage (Caldwell, ID: Caxton Printers, 1953).
