In politics, a reactionary is a person who favors a return to a previous state of society which they believe possessed positive characteristics absent from contemporary society. As a descriptor term, reactionary derives from the ideological context of the left–right political spectrum. As an adjective, the word reactionary describes points of view and policies meant to restore a status quo ante. As an ideology, reactionism is a tradition in right-wing politics; the reactionary stance opposes policies for the social transformation of society, whereas conservatives seek to preserve the socio-economic structure and order that exists in the present. A conservative might turn reactionary, when prioritizing older traditions over recently accepted ones. In popular usage, reactionary refers to a strong traditionalist conservative political perspective of a person opposed to social, political, or economic change. In the 20th century, reactionary politics was associated with restoring values such as discipline, hierarchy and respect for authority and privilege.
