Wikipedia
A political prisoner is someone imprisoned because they have opposed or criticized the government responsible.
The term is used by persons or groups challenging the legitimacy of the detention of a prisoner. Supporters of the term define a political prisoner as someone who is imprisoned for his or her participation in political activity. If a political offense was not the official reason for detention, the term would imply that the detention was motivated by the prisoner's politics.
