oligarhiad
Oligarchiads are hypothetical periods of societal upheaval characterized by the collapse of established power structures and the subsequent struggle for dominance among a small group of wealthy or influential individuals. The term, derived from "oligarchy" (rule by a few), suggests a transition phase where traditional political systems falter, leading to a power vacuum. In such scenarios, it is theorized that pre-existing economic elites, or newly emerging ones, would vie for control, potentially leading to prolonged instability, conflict, or the establishment of a new, albeit potentially less stable, oligarchic order.
The concept of an oligarchiad is largely speculative and often explored in speculative fiction, political science
