Iran-Iraq War (1980–1988)

The Algiers Treaty of March 6, 1975, signed by Iran’s Shah Mohammad Reza Pahlavi and then vice president of Iraq Saddam Hussein, was intended to solve long-standing border and waterway disputes between the two neighboring countries.

Iran-Iraq War (1980–1988)

However, with the overthrow of the shah in 1979, which put Iran in the hands of Islamic fundamentalists, the political dynamics changed. By 1980 Iran’s new leaders started to hint that they did not feel obligated by the shah’s earlier commitments, and Iraqi leaders were complaining that Iran still had not returned certain border areas promised under the 1975 treaty.

In September 1980 Iraqi armed forces moved to reclaim those lands, and on September 22 they crossed the border into Iran. The invasion had consequences that Iraqi president Hussein had not expected.


In launching the attack on Iran, Hussein thought the war would be brief and would lead to the downfall of Iran’s religious leader, the Ayatollah Khomeini, whom Hussein disliked. Instead, the power of Khomeini and other Islamic revolutionaries increased as Iranians united and rallied to support the war.

Few had expected Iraq to win the war outright. Although Iraq had better technology, more weapons, and a stronger air force, Iran had three times the population and about four times the geographic area of Iraq. Thus the Iran-Iraq War seesawed back and forth for eight grueling years.

Some methods of World War I were employed; Iran, for example, often conducted useless infantry attacks, using “human assault waves” made up in part by young, untrained conscripts, as in the Kerbala offensives, which were repulsed by the superior air- and firepower of the Iraqis.

Iraq, concerned with the war’s trench warfare and stalemate, had its overtures for a peace agreement undercut when its reputation was tainted by United Nations reports that it had used deadly (and illegal) chemical weapons against Iranian troops in 1984.

Although both Iran and Iraq attacked each other’s oil-tanker shipping in the Persian Gulf, Iran’s attacks on Kuwait’s and other gulf states’ tankers caused the United States and several Western European nations to station battleships in the gulf to protect those tankers.

This in turn led, on July 3, 1988, to the accidental shooting down of an Iranian civil airliner by the U.S. cruiser Vincennes, which killed all 290 crew members and passengers aboard.

As many as 1 million people died in the Iran-Iraq War, approximately 1.7 million were wounded, about 1.5 million were forced to flee as refugees, and major cities were destroyed on both sides. The oil industries of both countries also suffered extensive damage due to the fighting; oil exports, and earnings from those exports, naturally dropped.

More important, the large oil reserves of Iran and Iraq represented the potential for significant international economic power, but both nations had together largely wasted $400 billion on the war and along with that the chance to build up their societies.

The effects of the war clearly reached beyond the two combatants. Iran’s need for additional weapons led to a compromising relationship for the administration of U.S. president Ronald Reagan in 1985. In the secret Iran-contra affair, Iran was able to obtain weapons from the United States (the country that Khomeini had called “the great Satan”) in exchange for the release of hostages in Lebanon.

At about the same time U.S. aid of all types began to appear in Iraq, whereas the Soviet Union supplied about two-thirds of Iraq’s weapons. The Iran-Iraq War also ended Khomeini’s attempts to spread his fundamentalist Islamic revolution abroad.

Although stymied in his ambitions to make Iraq the leading power in the Persian Gulf (and the Arab world), Iraqi president Hussein learned new fighting strategies that he would later use against another neighboring country, Kuwait, which had been his ally during the conflict.

By the time a cease-fire finally arrived on August 20, 1988, the Iran-Iraq War had been the longest and most destructive conflict in the post–World War II era, and none of the basic friction points between Iran and Iraq had been settled.

However, in August–September 1990, while Iraq was busy with its invasion of Kuwait, Iraq and Iran quietly restored diplomatic relations, and Iraq agreed to Iranian terms for the settlement of the war: the removal of Iraqi troops from Iranian territory, division of sovereignty over the Shatt al Arab waterway, and an exchange of prisoners of war.

Saddam Hussein

Saddam Hussein was born in Al Awja near Tikrit, Iraq, to a poor family. He was raised mostly by an uncle and attended school in Baghdad. As a young man he joined the Ba’ath Party. After Hussein was involved in an abortive attempted to assassinate Abdul Karim Qassem, the leader of the 1958 Iraq revolution, he fled to Egypt, where he studied law.

When the Ba’ath seized power in 1963, he returned to Iraq but was soon imprisoned for another attempt to overthrow the regime. He escaped from prison in 1966 and was elected assistant general secretary of the Ba’ath.

Under the patronage of Ahmed Hassan al-Bakr, to whom he was related by blood, Hussein rose in power following the 1968 Ba’athist-led coup. In 1975 Hussein and Mohammad Reza Shah Pahlavi signed the Algiers Accord, which led to the Iran-Iraq Treaty of International Boundaries and Good Neighborliness, whereby the eastern portion of the Shatt al Arab was ceded to Iran. The agreements were a victory for Iran, and Hussein subsequently argued that Iraq had only signed under duress.

In 1979 Hussein ousted the ailing al-Bakr and assumed leadership of the Ba’ath Party and the nation. He emulated the Stalinist approach to government, establishing a totalitarian state based on a cult of personality.


He ruthlessly purged possible dissidents within the Ba’ath Party, closely controlled the media and communications systems, and had the populace—especially the youth—indoctrinated in loyalty to himself. Although not a professional soldier, Hussein often appeared in military uniform, and he curried favor with the army.

His regime was a secular one, and he closely monitored Shi’i clerics and Islamist movements. He appointed relatives and close associates from Tikrit to key government positions and demanded absolute loyalty. However, his regime also improved education, healthcare services, and the status of women.

Hussein initiated the Iran-Iraq War (1980–88) ostensibly to recover the Shatt al Arab but also to contain the Shi’i-led Iranian revolution. The resulting war of attrition led to massive human, military, and economic losses for both sides. Neighboring Arab nations in the Gulf and Saudi Arabia, fearing the export of the Iranian revolution, assisted Iraq with loans and aid.

From the Iraqi perspective the Arab regimes were paying for the war with money, and Iraq was paying with the blood of its soldiers. After the war Hussein downplayed his former secularism and adopted a more Islamic approach. He also launched major offensives, including the use of poison gas, against Kurdish forces in northern Iraq.

With the collapse of the Soviet Union, a major ally, Iraq became more isolated and found it increasingly difficult to obtain loans or assistance to rebuild its war-torn economy.

Hussein also recognized the mounting hostility of his former Arab allies and resented the refusal of Kuwait to forgive wartime loans. He also accused Kuwait of illegally slant-drilling for petroleum into Iraq. In August 1990, he ordered the invasion of Kuwait.

Kuwait quickly fell to the Iraqi forces and was incorporated into Iraq. The international community, including the Arab world, condemned the invasion and after a month of massive aerial bombardment in the so-called First Gulf War, coalition forces, led by the United States, moved into Kuwait.

The Iraqi army crumbled and hastily retreated. The coalition established no-fly zones that essentially created an autonomous Kurdish region in the north.

However, Hussein crushed uprisings, especially among the large and disaffected Shi’i population in southern Iraq. Iraq managed to rebuild much of its infrastructure, and water and electricity services were restored to major cities.

In spite of a decade of international sanctions that resulted in the deaths of tens of thousands of mostly civilian Iraqis, Hussein clung to power. International diplomacy and arms inspections resulted in the demilitarization and destruction of most of the Iraqi military arsenal, but although severely weakened, the military remained intact. Hussein’s sons Uday and Qusay became increasingly powerful during the 1990s, and their erratic behavior and violence terrorized those around them.

Saddam Hussein’s regime was overthrown in the 2003 U.S.-led invasion of Iraq (the Second Gulf War). As U.S. forces entered Baghdad many leaders of the regime, including Hussein and his sons, went into hiding. His sons were found and killed, and U.S. forces ultimately captured Hussein, who was then put on trial for crimes committed during his rule.

During the protracted trial, Hussein adopted a belligerent tone, maintaining that he was still the legitimate ruler of Iraq, but he was found guilty and executed. A new Iraqi regime was established, and the Ba’ath Party was banned from holding positions in government or schools.

The Iraqi army was also disbanded, but the nation continued to face tremendous economic and social problems as sectarian fighting broke out and massive opposition to foreign occupying forces erupted throughout much of the country.
