Saddam Hussein goes on trial in Baghdad for crimes against humanity.

The trial of Saddam Hussein was the trial of the deposed President of Iraq Saddam Hussein by the Iraqi Interim Government for crimes against humanity during his time in office.

The Coalition Provisional Authority voted to create the Iraqi Special Tribunal (IST), consisting of five Iraqi judges, on 9 December 2003, to try Saddam Hussein and his aides for charges of war crimes, crimes against humanity, and genocide dating back to the early 1980s.

Hussein was captured by U.S. forces on 13 December 2003. He remained in custody by United States forces at Camp Cropper in Baghdad, along with eleven senior Ba'athist officials. Particular attention was paid during the trial to activities in violent campaigns against the Kurds in the north during the IranIraq War, against the Shiites in the south in 1991 and 1999 to put down revolts, and in Dujail after a failed assassination attempt against Saddam on 8 July 1982, during the IranIraq War. Saddam asserted in his defense that he had been unlawfully overthrown, and was still the president of Iraq.

The first trial began before the Iraqi Special Tribunal on 19 October 2005. At this trial Saddam and seven other defendants were tried for crimes against humanity with regard to events that took place after a failed assassination attempt in Dujail in 1982 by members of the Islamic Dawa Party (also see human rights abuses in Iraq under Saddam Hussein). A second and separate trial began on 21 August 2006, trying Saddam and six co-defendants for genocide during the Anfal military campaign against the Kurds of northern Iraq.

On 5 November 2006, Saddam was sentenced to death by hanging. On 26 December, Saddam's appeal was rejected and the death sentence upheld. No further appeals were taken and Saddam was ordered executed within 30 days of that date. The date and place of the execution were secret until the sentence was carried out. Saddam Hussein was executed by hanging on 30 December 2006. With his death, all other charges were dropped.

Critics viewed the trial as a show trial that did not meet international standards on the right to a fair trial. Amnesty International stated that the trial was "unfair," and Human Rights Watch judged that Saddam's execution "follows a flawed trial and marks a significant step away from the rule of law in Iraq." Several months before the trial took place, Salem Chalabi, the former head of the Iraq Special Tribunal (which was established to try Hussein), accused interim Iraqi Prime Minister Iyad Allawi of pushing for a hasty show trial and execution, stating: "Show trials followed by speedy executions may help the interim government politically in the short term but will be counterproductive for the development of democracy and the rule of law in Iraq in the long term."

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.
