Behind the Facade of Unity: Communist Party of Czechoslovakia (KSC) and Socialist Unity Party of Germany (SED) after 1985 is a comparative study analysing the dynamics of non-democratic regimes in the Czechoslovak Socialist Republic and German Democratic Republic in the late eighties. The author's approach to the subject is inspired by debate between proponents of the theory of totalitarianism and the pluralist school, which occurred in Western political science in the 1960s.
