Pan-Iranism is an ideology that advocates solidarity and reunification of Iranian peoples living in the Iranian plateau and other regions that have significant Iranian cultural influence, including the Persians, Azerbaijanis (a Turkic-speaking group culturally Iranian), Gilaks, Lurs, Mazanderanis, Kurds, Zazas, Talysh, Tajiks, Tats, Pamiris, Pashtuns, Ossetians, Wakhis, Yaghnobis and Balochs. The first theoretician was Mahmoud Afshar Yazdi. According to the Routledge Handbook of Persian Gulf Politics: "One important point distinguishing radical nationalism of pan-Iranism from pan-Arab or pan-Turk orientations in the region is the fact that the Iranian version does not include irredentist plans in its political program.

The ultimate purpose was to persuade these populations to secede from the larger political entities to which they belonged and join the new pan-Turkic homeland. It was the latter appeal to Iranian Azerbaijanis, which, contrary to Pan-Turkist intentions, caused a small group of Azerbaijani intellectuals to become the strongest advocates of the territorial integrity of Iran. After the constitutional revolution in Iran, a romantic nationalism was adopted by Azerbaijani Democrats as a reaction to the pan-Turkist irredentist policies threatening Iran's territorial integrity. It was during this period that Iranism and linguistic homogenization policies were proposed as a defensive nature against all others. Contrary to what one might expect, foremost among innovating this defensive nationalism were Iranian Azerbaijanis. They viewed that assuring the territorial integrity of the country was the first step in building a society based on law and a modern state. Through this framework, their political loyalty outweighed their ethnic and regional affiliations. The adoption of these integrationist policies paved the way for the emergence of the titular ethnic group’s cultural nationalism. Geographically and culturally, Greater Iran is generally acknowledged to include the entire Iranian plateau and its
