Give at least one example of an Autocracy

An autocracy is a system ruled by one person. Nazi German is an example of autocracy. Hitler directed all the activities inside Germany at that time.

One historical example was Tokugawa shogunate (Edo shogunate) was an autocratic Japan under the rule of Tokugawa Ieyasu.

One fictional example is the Empire of Star Wars, under the rule of the Sith Emperor Palpatine.

Explanation:

Edo shogunate emerged in feudal Japan after a series of conflicts between clans and houses.  Tokugawa was able to seize power of the nation through cunning battle tactics and diplomacy, leading to his control of the nation.  This led the foundation for the Empire of Japan to be established later in history.

The Empire in Star Wars started a republic that fell when the cunning ruler Emperor Palpatine seized power of the senate and made the voting process completely useless.  Using his cunning and leadership ability, he controlled the entire region of the republic turned empire, leading to his ultimate control of the known galaxy.
