Moscow Helsinki Group
From the members of the Moscow Helsinki Group, 1978 saw its members Yuri Orlov, Vladimir Slepak and Anatoly Shcharansky sentenced to lengthy labor camp terms and internal exile for "anti-Soviet agitation and propaganda" and treason. Another wave of arrests followed in the early 1980s: Malva Landa, Viktor Nekipelov, Leonard Ternovsky, Feliks Serebrov, Tatiana Osipova, Anatoly Marchenko, and Ivan Kovalev. Soviet authorities offered some activists the "opportunity" to emigrate. Lyudmila Alexeyeva emigrated in 1977. The Moscow Helsinki Group founding members Mikhail Bernshtam, Alexander Korchak, Vitaly Rubin also emigrated, and Pyotr Grigorenko was stripped of his Soviet citizenship while seeking medical treatment abroad.
