The Iran-Iraq War started on September 22, 1980, when Iraqi forces invaded Iran by launching a full-scale invasion across the border. The primary reason for the conflict can be traced back to territorial disputes and longstanding animosity between the two countries. One of the main triggers for the war was the border disputes between Iran and Iraq over the Shatt al-Arab waterway, a strategic waterway that served as the main access point to the Persian Gulf for both countries. Additionally, there was a long history of enmity between the two nations, fueled by ideological differences, religious tensions, and strategic interests in the region.
