What is oligarcy?

Well, darling, an oligarchy is when a small group of people, usually the rich and powerful, control a country or organization. It's like a fancy exclusive club where only a handful of elites get to make all the decisions while the rest of us peasants just have to deal with it. So, in a nutshell, it's basically a posh version of a Dictatorship with a sprinkle of high society drama.
