A government led by a single entity with absolute powers is referred to as autocracy. In an autocratic system, one individual or a small group holds significant or total control over the state, making decisions without consent from the populace. Autocracy can manifest in various forms, including dictatorships and monarchies. Such systems often lack democratic processes, leading to limited political freedoms and a concentration of power, which can stifle dissent and restrict civil liberties for the sake of maintaining authority.
