The globalization process, which originally dominated only the economic sphere, subsequently led to profound social, political and cultural transformations, having a significant impact on culture and identity. In this context, tolerance is becoming a fundamental source of the peaceful coexistence of multi-ethnic and multicultural societies, facilitating cooperation and avoiding confrontations/ conflicts of values and norms. In this study, we propose to define the concept of tolerance, to elucidate the importance of promoting tolerance and education for tolerance in the context of the diversity in the contemporary world. Otherwise, tolerance stops violent extremism and genocide, provides prosperity and equal opportunities for the development of cultures, helps us to organize and maintain a constructive intercultural dialog.
