[1] Some academic economists have used revisionism to describe post-Stalinist, Eastern European writers who criticized one-party rule and argued in favour of freedom of the press and of the arts, intra- and sometimes inter-party democracy, independent labour unions, the abolition of bureaucratic privileges, and the subordination of police forces to the judiciary power.
Revisionism is most often used as an epithet by those Marxists who believe that such revisions are unwarranted and represent a watering down or abandonment of Marxism—one such common example is the negation of class struggle.
Those who opposed Karl Marx's revolution through his lens of class struggle and sought out non-revolutionary or more conciliatory means for a change are known as revisionists.
Eduard Bernstein, a close acquaintance of Marx and Friedrich Engels, was one of the first major revisionists, and was prominent in the Social Democratic Party of Germany (SPD).
[5] The views of Bernstein gave rise to reformist theory, which asserts that socialism can be achieved through gradual peaceful reforms from within a capitalist system.
