Anti-Iranian sentiment in Azerbaijan
Anti-Iranian sentiment in Azerbaijan dates back to 1918 when the first Azerbaijani nation was emerging under a pan-Turkist ideology. From thenceforward, political elites with pan-Turkist-oriented sentiments in the area that comprises the present-day Azerbaijan Republic have depended on the concept of ethnic nationalism to create an anti-Iranian sense of ethnicity among Iranian Azerbaijanis.
