19 17 The October Revolution also marked two completely different times in the history of Russian literature in the 20th century. After the revolution, about half of the writers emigrated, and Russian literature was divided into two sections: "domestic Russian literature" (the main part of Soviet literature) and "foreign Russian literature" (expatriate literature).

From the October Revolution to the 1920s, there were many domestic literary and art groups and various new slogans emerged one after another. There are mainly proletarian cultural associations (19 17- 1932), imagists (191927) and Serrapi Weng brothers. "Russian Federation of Proletarian Writers" (Lapp for short, 1925- 1932), etc. , are more influential literary groups. Among them, "Proletarian Cultural Association" and "Lapp" are the largest, and their theoretical propositions show the gradual rise of ultra-left literary thoughts. In terms of theoretical criticism, many factions were active at the same time in the 1920s. For example, the Marxist literary criticism represented by Lunacharski (1875-1933), the realistic criticism represented by Yakang Wollonski (1884-1943), and Fritsch (1873).
