Nowadays, multiculturalism is a frequently used term especially when dealing with integration problems of immigrants from Islamic countries into the majority society. But the term 'multiculturalism' is used too generally without being defined. This paper aids at finding the precise definition of the concept by relying on the opinions of major scholars of multiculturalism. Multiculturalism and its attributes are subsequently confronted with social processes and the possibility of the use of multiculturalism in education system is reviewed. Given that the United Kingdom developed an integration policy based on multiculturalism, in the case study the author critically analyses its impact on societal relations in this country. In this study ideas of relevant theorists of multiculturalism gained as a result of semi-structured interviews are quoted.
