Pan-Iranist Party

The Pan-Iranist Party (Persian: حزب پان‌ایرانیست, romanized: Ḥezb-e Pān-Irāni) is an opposition political party in Iran that advocates pan-Iranism. The party is not registered and is technically banned, however it continues to operate inside Iran.

During the Pahlavi dynasty, the party was represented in the Parliament and considered a semi-opposition within the regime, allowed to operate until officially denouncing Iran's assent to Bahraini independence in 1971. The party was forced to close down and merge into the Resurgence Party in 1975.

It is an occasional supporter of the major nationalist party, National Front, and was nationalist with respect to its ideology. The Pan-Iranist Party was an anti-communist organization and regularly battled Tudeh Party of Iran mobs in the streets of Tehran. In the context of the 1940s, it is described as a "secular ultranationalist party", whereas in that of the mid-1960s, it is described as a "secular nationalist" party. Nowadays, the party is marked by opposing the pan-Islamism of the post-1979 Iranian government, as well as of the threats posed by Islam, Islamic parties, and Islamic organizations in Iran aimed at ruining Iran's territorial integrity and cultural-civilizational heritage. Unlike pan-Arabist and pan-Turkist parties in the region, the pan-Iranist party currently does not advocate the return of Iran's former lands through irredentist and revanchist plans, and its political program does not incorporate such plans either. Rather, it advocates the cultural integration of citizens with a shared Iranian cultural heritage.

The Pan-Iranist Party spoke supportive of the Iranian Green Movement in 2009 and its discourse was revived in the 2010s by Iranian Principlists who tactically adopted its positions amidst Iran–Saudi disagreements and clash.
