Союз освобождения
In 1904, Kuskova and Prokopovich became founding members of the liberal Union of Liberation, subsequently renamed the Constitutional-Democratic Party (KDP). The party demanded democratic political reforms and modest social reforms to benefit the working class. It united a number of former Marxists, notably P.B. Struve (who had written the RSDRP's first programme), and the philosophers N.A. Berdyaev and S.L. Frank, with a number of former Narodniks, such as A.V. Peshekhonov, N.F. Annensky and V.A. Myakotin, and with national liberals like P.N. Miliukov who had no socialist background at all. For some time, the ex-Marxists in the KDP maintained contact with the German Social-Democrats and insisted that they were still socialists, but that Russia was not ripe for socialism and must first have a capitalist democracy.
