In the late eighteen-seventies, the German Social Democratic Party, while still healing the wounds of old battles between Lassalleans and Eisenachers, was confronted by foes who delivered attacks on two levels. On the one level, Bismarck and his supporters fought energetically to annihilate the party with the passage of the Socialist Law (October 21, 1878). After some initial faltering steps, the Social Democrats found a firm footing and struggled successfully to preserve their political existence. The movement was preserved, even though the party organization, its affiliates and its newspapers were suppressed. On another level, the Social Democrats faced an ideological challenge. Their political suppression broadly paralleled the emergence of a conservative socialism which flourished for a short time in a variety of forms. Whatever clothing it wore, conservative socialism aimed to undermine the growing appeal of Social Democracy to the working-men of Germany. A theory of State Socialism was the most attractive garment designed by conservative social thought. The response of the Social Democratic Party to the various facets of this conservative socialism is a significant chapter in the history of the German socialist movement.
