Along with
Abdel Karim Qasim and other Iraqi military officers, Arif was a member of the clandestine organisation, the Free Officers of Iraq. Like Qasim, Arif served with distinction in the otherwise unsuccessful
1948 Arab–Israeli War, where he captured
Jenin in what is now the
West Bank part of
Palestine from
Israeli Defence Forces. During the summer of 1958, Prime Minister
Nuri al-Said ordered Iraqi troops under Arif to aid
Jordan, as part of an agreement of the
Arab Federation. Instead, however, he led his army units into
Baghdad and on 14 July launched a
coup against the
Hashemite monarchy. Qasim formed a government under the newly proclaimed republic and Arif, his chief aide, was appointed deputy prime minister, interior minister, and deputy commander-in-chief of the armed forces. Almost immediately however, tensions rose between the
pan-Arabist Arif and Iraqi nationalist Qasim who also had the support of the
Iraqi Communist Party. The former supported a union with the
United Arab Republic (UAR) — composed of
Egypt and
Syria — under president
Gamal Abdel Nasser, but the latter opposed merging with the UAR. As a result, the two leaders engaged in a power struggle, ending in Qasim prevailing and the removal of Arif from his positions on 12 September. He was appointed the low-ranking post of ambassador to
Bonn. Arif refused to take up the post and upon returning to Baghdad on 4 November, he was promptly arrested for plotting against the state. He was sentenced to death along with
Rashid Ali al-Gaylani in February 1959. == President of Iraq ==
