This paper is dealing with problem of assimilation in the novel Chlieb by Jozef Cíger Hronský. Chlieb is reflecting interesting part of Slovak history between two wars, where the issue of nationality was very important and Slovak literature was one of the ways how to deal with it. This using of literature in a “politic function” was very popular among our writers in those days. Hronský uses characters of Czech family as one of main problems in this novel. At the example of Osterčílek’s family author is trying to prove assimilation of another nation by very strong community of Slovak people in Bacúch. He uses marriage, funeral and job as formal reasons for staying in village Bacúch. This theme was chosen because of Hronský’s important role in Slovak politics and culture.
