Definition of COUP D’ÉTAT

: a sudden decisive exercise of force in politics; especially : the violent overthrow or alteration of an existing government by a small group.

Editor’s note: Anyone who doesn’t think it was violent should consider the massive damage that was subsequently inflicted on The Mystical Body of Christ.  Anyone who doesn’t think it was political should see what they did to Traditional Catholics.
