The patriotism and nationalism are the poetic themes that poets influenced by socio-political conditions have paid attention to them for the sake of national unity and the freedom of societies and nations from colonialism. Rosafi and Shahriar are the contemporary Iraqi and Iranian poets, respectively, whose poems clearly show these themes. This paper tries to explore the poetry of the two poets to examine the concept of nationalism and the common themes related to the issue of national unity. The research method in this paper is based on the similarity of socio-political areas as well as adaptive school of Eastern Europe (Salafiyah School). Given the fact that the two poets were living in the same political environment, country has taken a new meaning in their poetry. Considering the nationalism, Rosafi has a wide and broad point of view. He has taken the unity of Arabic country as his aim. But from Shahriar’s point of view, Solidarity and Nationalism related to his country, Iran. He has invited Iranian ethnic groups, particularly the Azeri language speakers to the unity for Iran.
