A political thriller is a thriller that is set against the backdrop of a political power struggle. They usually involve various extra-legal plots, designed to give political power to someone, while his opponents try to stop him. They can involve national or international political scenarios. Political corruption, terrorism, and warfare are common themes. Political thrillers can be based on true facts such as the assassination of John F Kennedy or the Watergate Scandal. There is a strong overlap with the conspiracy thriller.
