The result of my search in Google shows the following:
"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 Ossetians, Kurds,Persians (including the Tajiks and Qizilbash), Hazaras, Pashtuns, Baluchis, and Zazas. Virtually all Pan-Iranists also include the Azeris (the first theoretician being an Azerbaijani by the name of Mahmud Afshar), who although speak a Turkic language with considerable Persian vocabulary, are claimed to be of native Iranian descent."
