A reactionary is a person who holds political views that favor a return to the status quo ante, the previous political state of society, which they believe possessed characteristics (discipline, respect for authority, etc.) that are negatively absent from the contemporary status quo of a society. As an adjective, the word reactionary describes points of view and policies meant to restore the status quo ante.
Political reactionaries are largely found on the right-wing of a political spectrum, though left-wing reactionaries can also exist. Reactionary ideologies can also be radical, in the sense of political extremism, in service to re-establishing the status quo ante. In political discourse, being a reactionary is generally regarded as negative; the descriptor "political reactionary" has been adopted by the likes of the Austrian monarchist Erik von Kuehnelt-Leddihn, the Scottish journalist Gerald Warner of Craigenmaddie, the Colombian political theologian Nicolás Gómez Dávila, and the American historian John Lukacs.
The French Revolution gave the English language three politically descriptive words denoting anti-progressive politics: "reactionary", "conservative" and "right". "Reactionary" derives from the French word réactionnaire (a late 18th century coinage based on the word réaction, "reaction") and "conservative" from conservateur, identifying monarchist parliamentarians opposed to the revolution. In this French usage, reactionary denotes "a movement towards the reversal of an existing tendency or state" and a "return to a previous condition of affairs". The Oxford English Dictionary cites the first English language usage in 1799 in a translation of Lazare Carnot's letter on the Coup of 18 Fructidor.
