The paper outlines the possible repercussions of the strong presence of Islamic representatives in Europe at the beginning of the 21st century. The percentage of Muslims in Europe increased from 2% in 1950 to 6% in 2020. The reception of the new wave of Muslim migration to the Old Continent leads to predictable consequences. Two scenarios can be considered. One of them is the growing perception of the threat from the increasing Muslim population in Europe. Another possible solution is their gradual integration. For both scenarios, clear premises based on known facts, socio-political decisions, ratified agreements and declarations of decision makers are presented. Discussions have been held on the emerging stereotypes that indicate an aversion to the growing presence of Islam on the Old Continent. Practices implemented to integrate the Muslim community have also been presented.
