What does reactionist mean?
A reactionist is a person who opposes significant social, political, or intellectual change and prefers the established order to reform or progress. The word is used especially in political contexts and often carries a condemnatory tone, suggesting stubborn resistance rather than ordinary caution or preference for continuity. As an adjective, “reactionist” describes people, ideas, movements, or policies shaped by that opposition. It overlaps with “reactionary” and “conservative,” but it is generally more pointed: a conservative may favor gradual change, whereas a reactionist is presented as seeking to preserve or restore an older order. The word can be historically descriptive when discussing opposition to reform, but in contemporary debate it is frequently a hostile label. Because it frames resistance to change as a defining attitude, it is stronger and more contentious than neutral terms such as “traditionalist.”
A person who strongly opposes change and supports preserving or restoring the existing order.
"The lecture attracted both reformers and reactionists."
Often used polemically, especially for opponents of social or political reform.

"The organization rejected the reactionist proposal."
Less common than the noun and generally used in political or historical discussion.
The regular plural refers to people who oppose change or favor restoring the established order.

Calling someone a reactionist goes beyond saying they are conservative: it suggests that resisting change is their defining political identity.

Where does reactionist come from?
The word was formed in the 19th century from “reaction” and the suffix “-ist,” meaning a person who holds or promotes a particular position. “Reaction” derives through French from Medieval Latin and ultimately from Latin reagere, meaning “to go back” or “act in return.” The same Latin root underlies cognates including “action,” “active,” “activity,” and “agency.”
