fascist (adj.)

1590s, from Latin fasces "bundle of rods containing an axe with the blade projecting" (plural of fascis "bundle" of wood, etc.), from Proto-Italic *faski- "bundle," perhaps from PIE *bhasko- "band, bundle" (source also of Middle Irish basc "neckband," Welsh baich "load, burden," perhaps also Old English bæst "inner bark of the linden tree"). Carried before a lictor, a superior Roman magistrate, as a symbol of power over life and limb: the sticks symbolized punishment by whipping, the axe-head execution by beheading. Hence in Latin it also meant, figuratively, "high office, supreme power."

1923, in names of organizations of Italian workers in the U.S., from anti- + fascist.

1922, originally used in English in 1920 in its Italian form fascismo (see fascist). Applied to similar groups in Germany from 1923; applied to everyone since the internet.

A form of political behavior marked by obsessive preoccupation with community decline, humiliation or victimhood and by compensatory cults of unity, energy and purity, in which a mass-based party of committed nationalist militants, working in uneasy but effective collaboration with traditional elites, abandons democratic liberties and pursues with redemptive violence and without ethical or legal restraints goals of internal cleansing and external expansion.
