The meaning of an inter-religious dialogue has increased in the context of globalization, which has put different ethnicities and religions face-to-face within the fledging "planetary community". Furthermore, it encouraged a remarkably emerging role of religion, in particular in politics. The dialogue became of key importance in Western Europe due to the Muslims turning into the largest diaspora of the region, and Islam – into the second religion after Christianity. The author dedicated this work to investigation of this dialogue's aspects, since the unceasing growth of the Muslim migration and terroristic threats cause the expansion of islamophobia and ethnic tension that have become a destabilizing factor in the region.
