Which type of governance is characterized by the concentration of power in a single individual, often without the consent of the governed?

The type of governance characterized by the concentration of power in a single individual is called autocracy. In an autocracy, one person has complete control over the government and makes decisions without needing approval from the people. This often leads to a lack of freedom for citizens, as they cannot easily challenge the leader's authority or express their opinions. For example, in a country ruled by an autocrat, the leader might decide laws and policies without asking the citizens what they want or need. This system can create a situation where the leader's interests are prioritized over the well-being of the general population.
