How can a dictatorship best be classified?

as a confederate system

as a monarchy

as an autocracy

as an oligarchy

The answer will be as a oligarchy

The answer is autocracy

oligarchy is when the government is controlled by a small group (like ancient sparta), which isnt the best answer since the most common definition of a dictatorship is absolute rule by a single person.

monarchy is king/queen

confederate system is a bunch of little systems (or something like that)
