This paper proposes a discussion of the Muslim presence in modern Western Europe and the trends that accompany it. The author argues that such debates could not be conducted in the absence of Muslims themselves and introduces Ziauddin Sardar (a modern British Muslim intellectual) and his thinking on “multiculturalism”. Sardar’s vision on the matter radically differs from the traditional interpretations, which usually involve European Union policies regarding ethnic minorities. Sardar’s theory is built on a broader context and develops such concepts as “diversity”, “identity”, and “power”. His approach transcends the boundaries of a limited geographic area and could be applied to non-Western regions. The author attempts to apply it to Kazakhstan, in an attempt to see how it could work in the Kazakh sociocultural context. The main focus is on the ethnic and religious characteristics of the Republic. Finally, the paper contains some suggestions for the further development of Sardar’s theory of multiculturalism. The conclusions offer a justification of the possibility and necessity to transform the idea of “multiculturalism” into “interculturalism”.
