 Several Georgian intellectuals petitioned Shevardnadze and the Soviet leader Leonid Brezhnev to address the situation.During 1981, at least five mass demonstrations took place in Georgia at which the Abkhaz question was raised once again alongside broader issues connected with the defense of Georgian language, history, and culture.The protesters also demanded the release of Avtandil Imnadze, the only person who was arrested in connection with the events of 14 April 1978 for having filmed the student demonstrations in Tbilisi.
