Authoritarian regimes are political systems where a single leader or a small group holds significant power, often limiting individual freedoms and political pluralism. In these systems, the government typically controls many aspects of life, including the media, education, and public expression, suppressing dissent and opposition. Citizens in authoritarian regimes often face restrictions on their rights, such as freedom of speech and assembly. Examples of such regimes include North Korea and China, where the government maintains strict control over political activities and public discourse, leading to a lack of democratic processes and accountability.
