Iraqi Republic (1958–1968)

Qasim specifically sited the north-south territorial limits from its highest point in the North and lowest point in the South identified in the regime's popular slogan as being "From Zakho in the North to Kuwait in the South", Zakho referring to the border then-and-now between Iraq and Turkey.[1] The Qasim government in Iraq and its supporters supported Kurdish irredentism towards what they called "Kurdistan that is annexed to Iran", implying that Iraq supported the unification of Iranian Kurdistan into Iraqi Kurdistan.[2] The Qasim government held an irredentist claim to Khuzestan.[3] It held irredentist claims to Kuwait, at the time controlled by Britain until its independence in 1961.[4]

During and after World War II, the UK reoccupied Iraq due to the 1941 Iraqi coup d'état in which four nationalist Iraqi generals, with German intelligence and military assistance, overthrew Regent 'Abd al-Ilah and Prime Minister Nuri al-Said and installed Rashid Ali as Prime Minister of Iraq. Ali was eventually ousted by the British and 'Abd al-Ilah and al-Said retook power. In 1947, the Iraqis started to negotiate a British withdrawal, and finally negotiated the treaty at Portsmouth on January 15, 1948, which stipulated the creation of a joint British and Iraqi joint defense board that oversaw Iraqi military planning and British control of Iraqi foreign affairs.[10]

Regional rivalries played a huge role in the 14 July Revolution. Pan-Arab and Arab Nationalist sentiment circulated in the Middle East and was proliferated by an anti-imperialist revolutionary, Gamal Abdel Nasser of Egypt. During and after World War II, The Hashemite Kingdom of Iraq was home to a number of Arab nationalist sympathizers. Arab nationalists viewed the Hashemite Monarchy as too beholden to British and Western interests. This anti-Hashemite sentiment grew from a politicized educational system in Iraq and an increasingly assertive and educated bourgeoisie. Iraqi Prime Minister Nuri al-Said expressed his interest in pursuing the idea of a federation of Arab States of the Fertile Crescent, and helped to create the Arab Federation of Iraq and Jordan, but reserved his enthusiasm about a Nasser espoused pan-Arab state. Al-Said joined the Arab league in 1944 on Iraq's behalf seeing it as a providing a forum for bringing together the Arab states, leaving the door open for a possible future federation. The charter of the League enshrined the principle of the autonomy for each Arab state and referenced pan-Arabism only rhetorically.

Iraq was left in ruins upon the conclusion of World War II, suffering from tremendous inflation and a subsequent plummet in living conditions. Prime Minister Nuri Al-Said and the Arab Nationalist regent, Abd al-Ilah, continually clashed on economic policy. Instead of cooperating to improve the quality of life for the Iraqi people and cut inflation, the Prime Minister and the regent could not agree on a cohesive economic policy.

Educated elites in Iraq began dabbling in the ideals espoused by Nasser's pan-Arabism movement. Within the officer corps of the Iraqi military, pan-Arab nationalism began to take root. The policies of Al-Said were disliked by certain individuals within the Iraqi military, and opposition groups began to form, modeled upon the Egyptian Free Officers Movement which had overthrown the Egyptian monarchy in 1952.

On 14 July 1958, a group that identified as the "Free Officers", a secret military group led by General Abd al-Karim Qasim, overthrew the monarchy. This group was markedly Pan-Arab in character, with the exception of Abd al-Karim Qasim, who was an Iraqi Nationalist, which would later hurt his relations with his colleagues. King Faisal II, the Regent and Crown Prince Abd al-Ilah, and Nuri al-Said were all killed.

The Revolution brought Muhammad Najib ar-Ruba'i and Abd al-Karim Qasim to power. Qasim's regime implemented a number of domestic changes to Iraqi society.

Opposition to Qasim from Arab Nationalist forces within the army culminated in the 1959 Mosul Uprising, which was an attempted coup launched with support from the United Arab Republic. Despite attracting support from local Arab tribes, the Mosul-based leadership of the coup was defeated in a number of days by loyal forces from within the Iraqi Army supported by the Iraqi Communist Party and local Kurdish tribes. Following the defeat of the coup Mosul was the scene of several days of unprecedented violence as all groups engaged in score-settling, using the post-coup chaos as a smokescreen, resulting in thousands of deaths.

Qasim's use of the Iraqi Communist Party to help put down the rebellion, and their growing strength within Iraq, convinced the Ba'ath Party in Iraq that the only way to stop the spread of the communists was to overthrow Qasim.

On 8 February 1963, Qasim was overthrown by a coup led by a mixture of the Ba'ath Party and sympathetic Arab Nationalist groups in the Iraqi Armed Forces. Qasim was unpopular in the Ba'ath Party and among Arab Nationalists largely for his focus on Iraqi Nationalism, as opposed to Arab Nationalism, and also because he was seen as being too close to the Iraqi Communist Party, which both groups viewed with a deep suspicion. Conflict between Qasim and certain officers of the Iraqi Armed Forces made them sympathetic to the idea of a coup.

Following Qasim's overthrow and execution members of the Ba'ath Party engaged in a house to house hunt for communists. Total deaths from the communist purge and the coup were around 5,000.

Although the Iraqi Communist Party had been greatly weakened by the anti-Leftists purges following the Ramadan Revolution, there still existed pockets of support for the party, particularly in Baghdad, which hosted some of the most militant party cells. A plan was eventually hatched and was put into action on 3 July 1963. The plan called for a mixture of 2,000 party members and rebel soldiers to take control over ar-Rashid army base in Baghdad, where 1,000 Qasim supporters and communists were being held, in the belief that the freed former officers could provide leadership and encourage other army units across Iraq to join the rebellion. The coup faced an unexpected level of opposition from the prison guards at the base, preventing them from releasing the officers and spreading the rebellion. The base was surrounded by forces from the Ba'ath Party National Guard Militia and the coup was put down.
