IPA: /ɔːˈtɒkrəsi/
KK: /ɔːˈtɒkrəsi/
A system of government where one person has complete control and makes all the decisions without any limits.
In an autocracy, the leader has the power to make laws and decisions without consulting anyone else.
Autocracy is formed from "auto-" (meaning self) and "kratos" (meaning power or rule). The word describes a system of government where power is concentrated in the hands of a single individual who rules by themselves.
Think of 'self' ('auto-') having 'power' ('kratos') — that's why autocracy means rule by one person.
