What kind of government is where the ruler determines policy without consulting either the people?

A government where the ruler determines policy without consulting the people is typically referred to as an autocracy. In an autocracy, power is concentrated in the hands of a single leader or a small group, and there is little to no input from the general population regarding governance. This can manifest in various forms, such as absolute monarchies or dictatorships, where decisions are made unilaterally and dissent is often suppressed.
