The Bolsheviks implemented several strategies to weaken the impact of Central Asian dastans, which are traditional epic narratives that play a significant role in the cultural identity and social cohesion of the Central Asian peoples. Here are some key approaches they used:

1. Cultural Repression: The Bolsheviks viewed traditional narratives, including dastans, as remnants of feudalism and bourgeois culture that needed to be eradicated. They promoted a new Soviet culture that emphasized proletarian values and sought to diminish the influence of pre-revolutionary cultural forms.

2. Promotion of Soviet Ideology: The Bolsheviks encouraged the creation of new literature and art that aligned with socialist ideals. They supported writers and artists who could produce works that reflected the revolutionary spirit and the goals of the Soviet state, thereby overshadowing traditional dastans.

3. Education and Propaganda: The Bolshevik regime established educational systems that emphasized Marxist-Leninist ideology. By promoting a curriculum that focused on Soviet history and ideology, they aimed to replace traditional narratives with state-approved content. This included the use of propaganda to discredit the values and themes found in dastans.

4. National Policies: The Bolsheviks implemented policies that aimed to create a unified Soviet identity, which often involved suppressing local customs and traditions. While they initially promoted some aspects of national cultures to gain support, over time, they sought to integrate these cultures into a broader Soviet identity, diluting the distinctiveness of dastans.

5. Censorship: The Bolshevik government exercised strict control over literature and the arts, censoring works that did not conform to the party line. This included traditional dastans, which were often seen as counter-revolutionary or as promoting outdated social structures.

6. Collectivization and Social Change: The social and economic upheaval caused by policies like collectivization disrupted traditional ways of life in Central Asia. As communities were transformed and traditional social structures weakened, the relevance and transmission of dastans were also affected.

Through these methods, the Bolsheviks aimed to reshape the cultural landscape of Central Asia, reducing the influence of dastans and other traditional forms of expression that could challenge the authority of the Soviet state.
