In the years after 1905, Social Democrats in Russia agonized over the form of struggle in which to engage. The defeats suffered in the revolution and the new legal possibilities offered after 1905 led to strains among the socialists and changed considerably the nature of their debates from the prerevolutionary years as each faction attempted to deal with the potential of a legal labor movement and the actuality of continued police repression. Paradoxically the years of “reaction” were also the seedbed of Russian trade unionism. Many Social Democrats, most notably the so-called likvidatory (“liquidators”), believed that the time had come to concentrate on the legal labor movement, to broaden its appeal and deepen its roots among the working class. Others, tied to the traditions of the underground party and the primacy of political work, opposed the new reliance on legal activity. All Social Democrats inside Russia were faced with the reality of economic depression, a decline in labor activism, and political repression. They faced together a strategic dilemma. The deeper they retreated into the underground, the more tenuous their ties with the workers became. Yet the more actively they engaged in trade unionist and other legal activities, the more vulnerable they were to police persecution.
