This article presents the results of a study conducted by the authors from January to May 2022 on the territory of the Stavropol Territory; an analysis of the conducted in-depth interview is presented. The authors describe the main ways to achieve the goal of forming a tolerant attitude towards representatives of various ethnic and cultural groups, including familiarizing students with the peculiarities of the national culture of other peoples through various creative competitions, ethnographic seminars, organizing joint excursion trips to the most interesting places of one or another subject of our country. Brief results are presented that are specific and narrow for studying the study of the characteristics of marriage by students of educational organizations of the Stavropol Territory, which are of particular interest, since for historical reasons it intricately combines the original Russian culture, the Cossacks and the peculiarities of the life of various peoples both in Russia and neighboring countries. As the main culturally conditioned models, the researchers singled out the primordialist and constructivist approaches, which determine a different way of interpreting ethnicity as such and the possibility of building constructive social ties. The article notes that certain ethnocultural contradictions are present, but significantly greater risks in building interethnic interaction are not associated with real contradictions in culture, but with ethnic stereotypes that have developed at the level of cultural and informational space, which provoke members of society to implement conflict models of interaction. The authors describe the process of legal prevention of conflicts on interethnic grounds, through the actions of our state represented by law enforcement agencies that are implementing a program to prevent extremism and terrorism among young people.
