He held numerous positions as a sports chairman, military officer and businessman, and was the head of the Iraqi Olympic Committee, Iraq Football Association, and the Fedayeen Saddam.
Uday was seen for several years as the likely successor to his father but lost the place as heir apparent to his younger brother, Qusay, due to injuries in an assassination attempt.
Following the United States-led invasion of Iraq in 2003, he was killed alongside Qusay and his nephew Mustafa by an American task force after a prolonged gunfight in Mosul.
He picked up his English teacher's Yorkshire accent and was described as a cheerful, bright child who was responsive to discipline, but an average student who struggled to concentrate.
[15][16] Ammo Baba, whose football teams won 18 tournaments and participated in three Olympics, said that Uday's punishment destroyed players' athletic abilities.
Baba said that half of the Iraqi athletes had left the country, and many had feigned illness before playing against strong competitors; he reportedly told his friends that if he died suddenly, they would know the reason.
Maad Ibrahim Hamid, assistant coach of the national football team, said that Uday rewarded players financially for winning and threatened them with imprisonment if they lost.
[30] Muhammad Asim Shanshal, head of the private office of Uday, said, "After a call from his mother, Sajida, told him that Kamel Hanna holds a joyful party for Saddam's second wife, Samira Shahbandar.
Shortly after the incident, Saddam got angry when he saw his half-brother in the hospital having difficulty walking, and he ordered the garage for Uday's luxury cars to be burned down.
Uday set up a barricade in front of his luxury cars in another nearby garage, armed himself with weapons, and waited for his father or his men to come.
Shortly after the grooms escaped to Jordan, Saddam burned the garage for Uday's luxury cars, saying, "While Iraqis are suffering from the embargo, this situation may send a false message.
Salman Sharif, one of the four would-be assassins who attacked Uday, learned that he regularly visited one of the luxurious streets of al-Mansour every Thursday at around 7 in the evening to pick up a girl.
Qusay told his father that the incident happened when Uday went to buy food to break his fasting, but Saddam said to Ali, "I know you were going to pick up girls there.
One of his former classmates, Aziz Al-Taee, said: There was a lot of fear in the female students that the guy had a tradition of choosing the most beautiful woman and trying to force her to date him then the most cases he will exclude her or that's one of his bodyguards to kill her after he rape her.
The chief of the Baghdad Hunting Club claimed that after a wedding party in the late 1990s, the bride suddenly disappeared, Uday's bodyguards locked all the doors, and the groom committed suicide.
Again, according to the allegations of Uday's servant, he witnessed forced custody of a crying bride at home in October 2002 and later said that the girl was killed, and her body was destroyed after she was raped.
Those who did not drink despite the threats were punished in three ways; having their hair and eyebrows shaven off, being beaten enough to stand up without touching their faces, and being subjected to a foot whipping before being forced to walk.
For example, after the killing of his uncle, Minister of Defense Adnan Khairallah in 1989, he started to pray regularly and never cut it, and he fasted every Monday and Thursday, but he used to drink alcohol continuously.
A lawyer said that Uday had ordered the head of a beautiful TV presenter to be shaved so that he could keep her long strands and then kept her naked in the Olympic Committee building for a month because she opposed his request.
They were spreading these rape rumours to discredit him, so it was not because Uday forced any girl to engage in obscenity, but we must note that any young man in any country has certain relationships and whims.
The penalty was to stop him from playing and not participate in the team, until he regained consciousness, and apologized, and if the player insisted on the mistake, his punishment was severe, refer to legal matter.
"[90] In the last years of the regime, the Fedayeen Saddam troops led by Uday cut off the heads of 30 prostitutes and threw them in front of their homes.
[91] A member of a guerrilla group whose duties were mainly special operations of Saddam's Fedayeen said that they assassinated figures opposed to the regime, shattering the appearance of those who were accused of hiding the truth from the government.
[102][103] In another house owned by Uday, "pornographic pictures, heroin bags, expensive liqueurs, vintage cars and HIV testing" was found.
[citation needed] Uday was 6 feet 6 inches tall and athletically built, though after the assassination attempt, he was partially paralyzed and would eventually use a wheelchair in private and a walking cane in public.
"[35] In a sign of loyalty to Saddam, the Vice-president of the Revolutionary Command Council Izzat al-Douri consented to marry his daughter Hawazin to Uday.
Saja went out to Sajida's house because her parents were in Geneva and tried unsuccessfully to persuade her uncle to agree to divorce her, but the president refused and asked her to talk to Uday about that.
[132] On the night of 21 July 2003, Nawaf al-Zaidan, who had been sheltering Uday, Qusay, Mustafa and their bodyguard Abdul-Samad in his mansion in the Falah neighbourhood of northeastern Mosul, left the villa and went to a nearby 101st Airborne base to turn in the two sons due to the combined $30 million reward.
[138] Newsweek claimed that the contents of Uday Hussein's briefcase consisted of Viagra, numerous bottles of cologne, unopened packages of men's underwear, dress shirts, a silk tie and a single condom.
[143] When criticized, the U.S. military's response was to point out that these men were no ordinary combatants, and to express hope that confirmation of the deaths would bring closure to the Iraqi people.
