The history of Holocaust and the process of teaching it in schools are of great interest not only to the educational community but also to the public in general. Why is it so important to know and study the tragedy of one nation while the entire globalized world is involved in the overall ethnic communication process, and cross-cultural interaction among various countries and ethnic groups has become multidimensional and constant? The matter is, globalization involves both centripetal and centrifugal forces clearly revealing tendencies towards unification of cultures and thus, manifesting the problem of preserving ethnic identity and ethno-cultural uniqueness of various peoples. Unfortunately, open promotion of national languages, cultures, and religious views by different ethnic groups often results in confrontations among ethnic communities and presents a challenge for people’s tolerance. The issue is especially urgent today when the world is shaken by ethnic conflicts with the spread of xenophobic attitudes, intolerance to representatives of different nations or different cultures, different behavior patterns or outlooks – all this might provoke genocide again.
