The violent overthrow of the bourgeoisie and civil government
by the proletariat is called a Coup d'etat.
Coup d’état, also called Coup, the sudden, violent overthrow of an
existing government by a small group. The chief prerequisite for a
coup is control of all or part of the armed forces, the police, and
other military elements. Unlike a revolution, which is usually
achieved by large numbers of people working for basic social,
economic, and political change, a coup is a change in power from
the top that merely results in the abrupt replacement of leading
government personnel.
A coup d'etat is the unlawful removal of a government by its
political adversaries, either by violent or non-violent means,
usually resulting in a government that does the very opposite the
former was doing or, in some cases, trying to keep the policies the
former sought to reverse.
