What type of government is characterized by an absolute dictator without restrictions from laws or opposition?

The type of government characterized by an absolute dictator without restrictions from laws or opposition is totalitarianism. In a totalitarian regime, the state recognizes no limits to its authority and seeks to regulate every aspect of public and private life. This often involves a centralized control by a single party or leader, where dissent is not tolerated, and opposition is severely suppressed.

In contrast, democracy involves shared governance, where power is derived from the people and is exercised through elected representatives, emphasizing individual rights and freedoms. Oligarchy refers to a government run by a small group of elite individuals, while monarchy involves rule by a royal family, which can be either absolute or constitutional. However, in a constitutional monarchy, the monarch's powers are limited by law, contrasting sharply with the unchecked power of a totalitarian dictator.
