revisionism

Political theory derived from Marxism that moderates one or more of the basic tenets of Karl Marx, and is hence condemned by orthodox Marxists.

The first noted Marxist revisionist was Eduard Bernstein, who in Germany in the 1890s questioned the inevitability of a breakdown in capitalism. After World War II the term became widely used by established communist parties, both in Eastern Europe and Asia, to condemn movements (whether more or less radical) that threatened the official party policy.
