The Arab–Iranian conflict or Arab-Persian conflict is a term which is used in reference to the modern conflict between Arab League countries and Iran. In a broader sense, the term is also used in reference to the historical ethnic tensions which have existed for centuries between Arabs and Persians as well as the historical religious sectarian conflict between Shia and Sunni Muslims, due to Saudi Arabia and post-revolutionary Iran seeing themselves as the champion leading states for Sunni Muslims and Shia Muslims, respectively.
