People who are extremely dedicated to a cause or belief, often to an excessive or fanatical degree.
From Greek 'zelotes' meaning 'zealous' or 'emulator,' from 'zelos' (zeal); entered English via Latin and Old French, originally referring to Jewish resistance fighters.
The word originally described a specific Jewish group fighting Romans in 66-70 CE, but became a general term for over-the-top believers—history transformed specific people into a universal category.
