The author examines publicist works and prose of the Russian and international movement’s prominent personality, diplomat, political writer and prose writer A.M.Kollontai (nee Domontovich). For the first time she came out as a political writer in «Obrazovanie» magazine (1898). In a series of her works Kollontai set collectivism of the proletarian morality against philosophy of individualism which, according to her, was represented by F.Nitsche. Kollontai devoted a particular attention to problems of women’s equality, of woman’s position within family and at work, of maternity protection. Kollontai linked change of women’s life with the necessity of drastic transformation of the social system. She devoted some of her fiction pieces to the topic of women’s social emancipation and assertion of women’s right to the free choice in love (these works were gathered in «Work bees' love». From a series of «Revolution of feelings and revolution of morals» stories' collection). At the present time Kollontai’s heritage increasingly attracts attention of researchers: historians, specialists in literary studies, sociologists including specialists in the gender issues.
