means A collective act of rebellion in which people rise up against an authority or government, usually suddenly and by force.

from A plain English compound, built from 'up' plus 'rising' — the noun form of 'rise,' which traces back to Old English 'risan,' to get up, ascend, or stand. The image is literally bodily: people who were kept down standing up. 'Rise' is related to a wider Germanic family of words for movement and growth, a cousin of Old Norse 'risa' and Old High German 'risan.' The figurative leap from standing up to revolting against power is an old and natural one — the same instinct that gives us 'insurrection' (Latin 'insurgere,' to rise upon).
