Iran's relationship with the Arab world has been complex and multifaceted over the centuries. While there have been periods of conflict and tension, there have also been long periods of cultural and intellectual exchange. Persian culture has had a profound impact on the Arab world, particularly in the areas of literature, philosophy, and the arts. For example, Persian mythology has had a significant impact on Arabic literature, particularly during the Islamic Golden Age.
