The theme of this work is multiculturalism and some of its aspects in France. The focus is on the first and second generation immigrants from African countries, especially countries of Maghreb. Decolonisation and Algerian War of independence, through this work, are seen as the beginning of multiculturalism in France, because of the cultural differences that immigrants from these areas bring in mainland. Considering that France is a secular state and there is no specific legislation relating to ethnic or racial minorities and religious communities, the existence of multiculturalism in France is questionable. But minorities have problems. These problems lead to riots, creating closed communities and the creation of "other" cultures. This work observed the problem of identity, which is most visible in the second-generation immigrants. The problem of identity resulted in the so-called other identitet, usually linked to parent's country of origin and religious identification through Islam. Religious differences and intercultural communication of different cultures in the Republic are also analyzed.
