A "political prisoner" is an individual who is incarcerated for their political beliefs or actions that challenge or oppose the established political system. Such prisoners are typically imprisoned not for committing criminal acts but for expressing dissent, advocating for human rights, or participating in political activities that are deemed threatening by the authorities. The term highlights the violation of fundamental human rights and often attracts international condemnation, as many political prisoners face harsh treatment, unfair trials, and lack of legal representation.
