insurrection

Etymology

PIE word *upó From Late Middle English insurreccion (“uprising against a government, rebellion, revolt; civil disorder, riot; illegal armed assault”) [and other forms], from Middle French insurrection, Old French insurreccïon (modern French insurrection), and from their etymon Latin īnsurrēctiōnem (rare), the accusative singular of īnsurrēctiō (“rising up, insurrection, rebellion”), from īnsurgō (“to rise up”), from in- (prefix meaning ‘in, inside, within’) + surgō (“to arise, get up; to rise”) (from sub- (prefix meaning ‘(from) beneath, under’) + regō (“to direct, govern, rule; to guide, steer; to manage, oversee”) (ultimately from Proto-Indo-European *h₃reǵ- (“to right oneself, straighten; just; right”))).

   No person shall be a Senator or Representative in Congress, or elector of President and Vice-President, or hold any office, civil or military, under the United States, or under any State, who, having previously taken an oath, as a member of Congress, or as an officer of the United States, or as a member of any State legislature, or as an executive or judicial officer of any State, to support the Constitution of the United States, shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof. But Congress may by a vote of two-thirds of each House, remove such disability. (1866, Fourteenth Amendment to the United States Constitution, Section 3)
