The article is devoted to the problem of the multiculturalism by Joseph Conrad, the English writer and the world classic of the 20th century, who, due to the preservation of his Polish national-cultural identity, and by estrangement from this identity in his artistic consciousness, was able to influence the intellectual and artistic atmosphere in England of his times. In this way, the Polish identity became a background for Conrad’s artistic creativity, and at the same time, universal values and criteria were the key to the successful acculturation in English society in its one of the most effective strategies – the integration strategy. In this case Conrad acquired another national-cultural identity, English, – while retaining his native, Polish. Undoubtedly, one of the most important issues touched by almost all researchers is his arrival in English literature, a Pole in origin, who only arrived in England in the twenty-first year, actually emigrating, and for a very short time becaming a venerable writer. It should be noted that, taking into account the peculiarities of English mentality, the task was rather uneasy. All this undoubtedly led to the development of a variety of approaches to understanding the creative personality and rich heritage of Joseph Conrad. Foreign literary and critical academic circles, which introduced the concept of «new English literature» (meaning the post-colonial period), do not take into account such figures of the English literary process as Joseph Conrad, whose work falls out of its chronological framework, and indicates that multicultural literature appeared on the approaches to the twentieth century. However, only nowadays it was possible that such an approach was based on the principles of multiculturalism, that is, the phenomenon justified in the 90s of the XX century, although, as the majority of scholars testify, it existed for a long time in cultural studies, literary criticism, art history and philosophy. We have chosen this approach. The research is devoted to the study of the problems of national-cultural identity by Joseph Conrad, as well as the mechanism of his acculturation in the conditions of emigration.
