Baghdad Pact

The Baghdad Pact was a regional security alliance signed in Baghdad on 24 February 1955, initially between Iraq and Turkey, and later joined that year by the United Kingdom, Pakistan, and Iran. Modeled loosely on NATO, it sought to create a "northern tier" of states bordering or near the Soviet Union to block Soviet southward expansion toward the Persian Gulf and warm-water access.

The pact was promoted heavily by US Secretary of State John Foster Dulles as part of the Eisenhower administration's containment strategy, though the United States itself never formally joined—it participated only as an observer and through bilateral defense agreements with member states, partly to avoid antagonizing Arab states and Israel. The alliance established a permanent secretariat and a council that coordinated military, economic, and counter-subversion cooperation.

The pact proved politically fragile. It deepened the rift between pro-Western Iraq under Prime Minister Nuri al-Said and Gamal Abdel Nasser's Egypt, which denounced it as a vehicle of Western imperialism and a rival to Arab League solidarity. The Suez Crisis of 1956 further strained the alliance by exposing divisions between the UK and its regional partners.

The decisive blow came with the 14 July 1958 Revolution in Iraq, when the Hashemite monarchy was overthrown by Free Officers led by Abd al-Karim Qasim. The new republican government withdrew from the pact in March 1959. The remaining members—Turkey, Iran, Pakistan, and the UK—renamed the organization the Central Treaty Organization (CENTO), headquartered in Ankara.

CENTO itself never developed an integrated military command comparable to NATO and is generally judged to have been a weak deterrent. It dissolved in 1979 following the Iranian Revolution and Pakistan's withdrawal, ending a 24-year experiment in formal Western-aligned collective defense across the northern Middle East and South-West Asia.
