Evolutionary Socialism was Bernstein's most significant work, and it set the stage for the Democratic Socialism of today. In Evolutionary Socialism, Bernstein was principally concerned with refuting Karl Marx's predictions about the imminent and inevitable demise of capitalism. Bernstein warned that a violent proletarian revolution, as in France in 1848, produced only reactionary successes, which undermined workers' interests. Therefore, he rejected revolution and instead insisted the best strategy to be patiently building up a durable social movement working for continuous nonviolent incremental change.
