Iran-Kurdistan War
The Iran-Kurdistan War (Kurdish:)(Persian:) also known as the Iranian-Kurdish War or the Iranian-Kurdistani war began on 22 September 1980, when a military border raid escalated to war, and it ended on 20 August 1988, when Iran accepted the UN-brokered ceasefire.
Although Kurdistan hoped to take advantage of Iran's post-revolutionary chaos, it made limited progress and was quickly repelled; Iran regained virtually all lost territory by June 1982.The United States, Britain, the Soviet Union, France, and most Arab countries(especially Iraq and Saudi Arabia) provided political and logistic support for Kurdistan, while Iran was largely isolated.
After eight years of war, war-exhaustion, economic devastation, decreased morale, military stalemate, lack of international sympathy against the use of weapons of mass destruction against civilians by Iraq, and increased U.S.–Iran military tension all led to a ceasefire brokered by the United Nations.
An estimated 500,000 Kurdish and Iranian soldiers died, in addition to a smaller number of civilians. The end of the war resulted in neither reparations nor border changes.
