The adjective reactionary is a political term meaning very conservative. It also functions as a noun describing someone who is politically reactionary. If you need an adjective meaning (1) tending to react or (2) characterized by reaction, go with reactive.

Reactionary is the opposite of radical (though radical is often used to describe extremes of any political persuasion). It comes from post-Revolutionary France, where the réactionnaires sought restoration of the old, monarchical order. In modern politics, the word denotes a steadfast conservatism, sometimes with fascist or xenophobic undertones. It’s often pejorative.
