Iranian influence refers to the political, cultural, and economic impact that Iran has on its neighboring countries and beyond. This influence is often seen in the context of Shia Islam, which Iran promotes as a unifying force among Shia communities in the region, particularly in Iraq, Lebanon, and Bahrain. Additionally, Iran's involvement in regional conflicts, such as its support for groups like Hezbollah and Houthi rebels, showcases its strategic interests. Through alliances and proxy relationships, Iran seeks to extend its reach and counterbalance the influence of rival powers, notably Saudi Arabia and the United States.
