Vice President of Iraq in the context of "Constitution of Iraq"

Saddam Hussein (28 April 1937 – 30 December 2006) was an Iraqi politician and revolutionary who served as the president of Iraq from 1979 until he was overthrown in 2003 during the U.S. invasion of Iraq. He previously served as the vice president from 1968 to 1979 and also as the prime minister from 1979 to 1991 and later from 1994 to 2003. A leading member of the Arab Socialist Ba'ath Party, he was a proponent of Ba'athism, a mix of Arab nationalism and Arab socialism. The policies and ideologies he championed are collectively known as Saddamism.

Born near the city of Tikrit to a Sunni Arab family, Saddam joined the revolutionary Ba'ath Party in 1957. He played a key role in the 17 July Revolution that brought the Ba'athists to power in Iraq and made him vice president under Ahmed Hassan al-Bakr. During his tenure as vice president, Saddam nationalized the Iraq Petroleum Company, diversified the economy, introduced free healthcare and education, and supported women's rights. He also presided over the defeat of the Kurdish insurgency in the Second Iraqi–Kurdish War and signed the Algiers Agreement with Iran in 1975, thereby settling territorial disputes along the Iran–Iraq border. Following al-Bakr's resignation in 1979, Saddam formally took power. During his presidency, positions of power in the country were mostly filled with Sunni Arabs, a minority that made up only about a fifth of the Iraqi population.

Field Marshal Ahmed Hassan al-Bakr (1 July 1914 – 4 October 1982) was an Iraqi military officer and politician who served as the president of Iraq from 1968 to 1979. He was a leading member of the revolutionary Arab Socialist Ba'ath Party and later the Baghdad-based Ba'ath Party and its regional organisation Ba'ath Party – Iraq Region (the Ba'ath Party's Iraqi branch), which espoused Ba'athism, a mix of Arab nationalism and Arab socialism.

Al-Bakr first rose to prominence after the 14 July Revolution, which overthrew the monarchy. In the newly established government, he was involved in improving Iraqi–Soviet relations. In 1959 al-Bakr was forced to resign from the Iraqi military; the then Iraqi government accused him of anti-government activities. Following his forced retirement, he became the chairman of the Ba'ath Party's Iraqi branch's Military Bureau. Through this office he recruited members to the Ba'athist cause through patronage and cronyism. Prime Minister Abd al-Karim Qasim was overthrown in the Ramadan Revolution (8 February); al-Bakr was appointed prime minister, and later, Vice President of Iraq in a Ba'ath-Nasserist coalition government. The government lasted for less than a year, and was ousted in November 1963.

Nouri Kamil Muhammad-Hasan al-Maliki (Arabic: نوري كامل محمد حسن المالكي; born 20 June 1950), also known as Jawad al-Maliki (جواد المالكي), is an Iraqi politician and leader of the Islamic Dawa Party since 2007. He served as the prime minister of Iraq from 2006 to 2014 and as the vice president from 2014 to 2015 and again from 2016 to 2018.

Al-Maliki began his political career as a Shia dissident opposed to former Iraqi president Saddam Hussein in the late 1970s, and rose to prominence after he fled a death sentence and went into exile for 24 years. During his time abroad, he became a senior leader of the Islamic Dawa Party, coordinated the activities of anti-Saddam guerrillas, and built relationships with officials from Iran and Syria, seeking their help in overthrowing Saddam's government. Both during and after the American-led occupation of Iraq (2003–2011), al-Maliki worked closely with the Multi-National Force (MNF–I), and continued to cooperate with the United States following the withdrawal from Iraq.
