The national language is one of the important components of the identity of any political and social system, whose negligence can lead to a lot of damages. The official languages have various social, political, legal, etc. functions, each of which can affect the fate of the countries. One of the important factors in the policies related to the national language is to consider the role of language in national unity and social solidarity. Considering the importance this issue, the present paper attempts to answer the following question using the analytical-descriptive method and library studies: ‘What is the impact of the Persian language on Iran's social solidarity and national unity?’ Some of the findings of the present study reveal that the Persian language has a strong relationship with the national unity of Iranians and it consolidates national solidarity and unity in Iranian society through the establishment of national identity, creation of effective interaction in society, instillation of the spirit of coexistence and avoidance of conflict, mediation between different language dialects in the country, public attachment, resistance culture, power generation, loyalty, etc. The history of the Islamic Iran shows that the Persian language has united Iranians against domestic and foreign enemies in different ages and has facilitated the process of conflictfree collective existence. To support the Persian language, we can take such measures as expanding media products, supporting research projects related to the promotion of the Persian language, increasing written products related to the Persian literature, supporting Persian language departments abroad, proliferating Persian language research journals, reinforcing Persian language courses in schools, etc.
