This incisive essay is more relevant now that it was when it was first published in 1952. From Garet Garrett at lewrockwell.com:
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.” And now, not far ahead, is a sign that reads: “No U Turns.”
If you say there were no frightening omens, that is true. The political foundations did not quake; the graves of the Fathers did not fly open; the Constitution did not tear itself up. If you say people did not will it, that also is true. But if you say therefore it has not happened, then you have been so long bemused by words that your mind will not believe what the eye can see, even as in the jungle the terrified primitive, on meeting the lion, importunes magic by saying to himself, “He is not there.” That a republic may vanish is an elementary schoolbook fact.
The Roman Republic passed into the Roman Empire, and yet never could a Roman citizen have said, “That was yesterday.” Nor is the historian, with all the advantages of perspective, able to place that momentous event at any exact point on the dial of time. The Republic had a long unhappy twilight. It is agreed that the Empire began with Augustus Caesar. Several before him had played emperor and were destroyed.
The first who might have been called emperor in fact was Julius Caesar, who pretended not to want the crown and once publicly declined it. Whether he feared more the displeasure of the Roman populace or the daggers of the republicans is unknown. In his dreams he may have been seeing a bloodstained toga. His murder soon afterward was a desperate act of the dying republican tradition, and perfectly futile. His heir was Octavian, and it was a very bloody business, yet neither did Octavian call himself emperor.
