The Gulf War was an armed campaign waged by a United States-led coalition of 35 countries against Iraq in response to the Iraqi invasion and annexation of Kuwait.

The Iraqi military invaded the neighbouring State of Kuwait on 2 August 1990 and fully occupied the country within two days. Different speculations have been made regarding the true intents behind the invasion, including Iraq's inability to pay Kuwait the more than US$14 billion that it had borrowed to finance its military efforts during the IranIraq War, and Kuwait's surge in petroleum production levels which kept revenues down for Iraq. Throughout much of the 1980s, Kuwait's oil production was above its mandatory OPEC quota, which kept international oil prices down. Iraq interpreted Kuwait's refusal to decrease its oil production as an act of aggression towards the Iraqi economy. The invasion of Kuwait was met with international condemnation, and economic sanctions against Iraq were immediately imposed by the United Nations Security Council in response. British prime minister Margaret Thatcher and U.S. president George H. W. Bush deployed troops and equipment into Saudi Arabia, and urged other countries to send their own forces to the scene. In response to the call, an array of nations joined the U.S.-led coalition, forming the largest military alliance since World War II. The bulk of the coalition's military forces were from the United States, with Saudi Arabia, the United Kingdom, and Egypt as the largest lead-up contributors, in that order. Kuwait and Saudi Arabia paid around US$32 billion of the US$60 billion cost.The initial conflict to expel Iraqi forces from Kuwait began with an aerial and naval bombardment on 17 January 1991, which continued for five weeks. During this period, Iraq began to launch missiles into Israel with the aim of provoking a response by the Israeli military, which the Iraqi leadership expected to prompt the coalition's Muslim states to withdraw and therefore jeopardize the alliance against Iraq. As the Iraqi missile campaign against Israel failed to generate the desired response, Iraq also launched Scud missiles at coalition targets stationed in Saudi Arabia. This was followed by a ground assault by the coalition into Iraqi-occupied Kuwait on 24 February. The offensive was a decisive victory for coalition forces, who liberated Kuwait and promptly began to advance past the IraqKuwait border into Iraqi territory. 100 hours after the beginning of the ground campaign, the coalition ceased its advance and declared a ceasefire. Aerial and ground combat was confined to Iraq, Kuwait, and areas straddling the IraqSaudi Arabia border.

The war marked the introduction of live news broadcasts from the front lines of the battle, principally by the U.S. network CNN. It has also earned the nickname Video Game War after the daily broadcast of images from cameras onboard American bombers during Operation Desert Storm. The Gulf War has gained notoriety for including three of the largest tank battles in American military history.

Saddam Hussein Abd al-Majid al-Tikriti (; Arabic: صدام حسين عبد المجيد التكريتي, romanized: Ṣaddām Ḥusayn ʿAbd al-Majīd al-Tikrītī; 28 April 1937 – 30 December 2006) was an Iraqi politician who served as the fifth president of Iraq from 16 July 1979 until 9 April 2003. A leading member of the revolutionary Arab Socialist Ba'ath Party, and later, the Baghdad-based Ba'ath Party and its regional organization, the Iraqi Ba'ath Party—which espoused Ba'athism, a mix of Arab nationalism and Arab socialism—Saddam played a key role in the 1968 coup (later referred to as the 17 July Revolution) that brought the party to power in Iraq.

As vice president under the ailing General Ahmed Hassan al-Bakr, and at a time when many groups were considered capable of overthrowing the government, Saddam created security forces through which he tightly controlled conflicts between the government and the armed forces. In the early 1970s, Saddam nationalised the Iraq Petroleum Company and independent banks, eventually leaving the banking system insolvent due to inflation and bad loans. Through the 1970s, Saddam consolidated his authority over the apparatus of government as oil money helped Iraq's economy grow rapidly. Positions of power in the country were mostly filled with Sunni Arabs, a minority that made up only a fifth of the population.Saddam formally took power in 1979, although he had already been the de facto head of Iraq for several years. He suppressed several movements, particularly Shi'a and Kurdish movements which sought to overthrow the government or gain independence, respectively, and maintained power during the Iran–Iraq War and the Gulf War. He ran a repressive authoritarian government, which several analysts have described as totalitarian, although the applicability of that label has been contested. Saddam's rule was marked by numerous human rights abuses, including an estimated 250,000 arbitrary killings and bloody invasions of neighboring Iran and Kuwait.In 2003, a coalition led by the United States invaded Iraq to depose Saddam. U.S. President George W. Bush and British Prime Minister Tony Blair erroneously accused Iraq of possessing weapons of mass destruction and having ties to Al-Qaeda. Saddam's Ba'ath party was disbanded and the country's first democratic elections were held. After his capture on 13 December 2003, the trial of Saddam Hussein took place under the Iraqi Interim Government. On 5 November 2006, Saddam was convicted by an Iraqi court of crimes against humanity related to the 1982 killing of 148 Iraqi Shi'a and sentenced to death by hanging. He was executed on 30 December 2006.
