In times when there are more and more violent Islamic groups who do not understand fundamentalism, arises the question of how can Islam overcome this issue. Multiculturalism, one of the most important characteristics of society nowadays, often contributes to this problem, especially if we take into consideration the fact that Islamic people often do not want to adapt to European or other countries in which they do not represent the majority of the population. The first part of this thesis is an introduction to Islam so that the reader can better understand the mentality of the Muslim community. Further, the second part is a review of the central theme of the paper - Islamic fundamentalism. This part also addresses the relation of Islam to the other people and to the deviant and violent groups who, because of their distorted view of fundamentalism, consider that the members of any other religion are infidels who should be converted to Islam. The third part is dedicated to guidelines to overcoming Islamic fundamentalism. It primarily emphasizes the value of dialogue between Muslims and Christians as a path towards the solution for this Islamic fundamentalism issue. Also, this section emphasizes the value, but also certain doubts and ambiguities about the assumptions of Islamic-Christian dialogue.
