The presence of the different ethnic groups in the ancient society of Iran has caused the cultural and social exchange throughout history. because Iran is a multi-ethnic country, the continuity and survival of the identity of Iranian culture throughout history owes a lot to different ethnic groups like Kurds, Azeris, Lors, Beluches, Torkamans, Arabs and Fars. Considering the liveliness of Iranian culture and the social cultural changes in Iran in recent decades, the people of Iran have found a more comprehensive understanding of the world, world culture and their Iranian culture. This recognition and awareness have not been without effect from the internal and external world. The theory that as a result of globalization, we will witness growth and development of ethnic identities and consequently also witness the challenging of national identity in Iran, theoretically and practically cannot be supported considerably. Because in parallel to the process of globalization and fro recognition of the type of connection between Iranian culture and world culture. We can suppose that it is not the separation and distinction of the cultures that do matter but rather the connectivity and interaction of them. Considering this supposition, the most important background for the spread of the universal spirit and globalized inclinations in the Iranian identity can be seen in its historical origin.
