Plutarch and his live details the Roman Republic in its final days. Political enemies beheaded and oligarchs trying to become rulers. As Grant notes in his preface:
Two elements perhaps stand out above all others in Plutarch's late republican Lives. The first is the unbridled pursuit of personal power. Every Life in this selection displays the incessantly disruptive and ultimately ruinous effects of competition and ephemeral collaboration for purely selfish ends between a handful of prominent individuals, none of whom was quite powerful enough to achieve sole supremacy until Caesar put an end to the dominance of the oligarchy that had spawned him in the last stage of its decline. The second is the amount of coverage that Plutarch sees fit to give to wars both foreign and civil.
To a certain extent this need occasion no surprise. In the eyes of the Roman ruling class military glory was the highest form of distinction to which its members might aspire. The biographer of leading Romans could hardly avoid writing about war, and a man's conduct in the field might well provide illuminating insights into those recesses of his character that Plutarch sought to penetrate. Yet much of his military narrative seems, as observed earlier, to be there for its own sake, regardless of any light it might shed on the protagonists’ moral or psychological make-up.
The reason for both these features of Plutarch's work lies in the standard perception of the republic and its fall that quickly developed under the empire. Everyone knew that the republican ruling class, by its dedication to the quest for wealth and personal power, had destroyed itself and the system of government it claimed to cherish. That Plutarch should share this perception is not remarkable. Explanation would be needed only if he did not.

So who is our ruling class today and given current events are they repeating themselves. It is truly worth understanding our history, it does repeat.
