Oligarchy, a form of governance marked by the concentration of authority in the hands of a small elite, has remained a persistent theme in political discourse. From Aristotle’s distinction between oligarchy and genuine aristocracy to Plato’s criticism of governance driven by wealth, writers have long explored its mechanisms. Charles Sumner denounced the "Slave Oligarchy," while Scott Nearing examined how ruling classes maintain dominance through self-interest.
Even democratic systems, as Robert Michels observed, are susceptible to oligarchic inclinations. Contemporary instances, ranging from Russian business magnates to the accumulation of wealth in the United States, highlight its continued significance as a structure in which influence—whether derived from nobility, riches, or ideology—remains firmly held by a select minority.
