Iran-Iraq War

Border war between Iran and Iraq, 1980 - 1988, also known as First Gulf War (both countries are on the coast of the Persian Gulf), and called the Gulf War before 1991, when that name was preempted by the Iraq-Kuwait conflict.

Iraq, a Soviet ally during the Cold War, received significant backing from the United States as well.

The war was characterized by extreme brutality, including the use of chemical weapons by Iraq. Because of Iran's poor relations with the international community, very little pressure was brought upon Iraq by the world community to curb these abuses.

The end of the war left the borders unchanged.
