This chapter examines the formation and development of the Arab League with particular emphasis on how it served as a compromise for the differences in the manner Arab leaders viewed nationalism, unity, and security. Egypt, and to a lesser extent Iraq, coordinated efforts to achieve a common Arab position related to the formation of the regional international organization. The chapter follows these efforts, in particular the discussions for common positions on Arab unity and Arab security at the 1944 Alexandria ConferenceAlexandria Conference and then the meeting to prepare a Charter. The narration then traces the 1945 San Francisco ConferenceSan Francisco Conference to develop a charter for the United Nations and Arab efforts to ensure the new global organization recognized the Arab League as an official regional organization representing Arab states and Arab interests. The Arab League’s first “test” of cooperation in these concepts appeared during the 1948 war with Israel and resulted in an unsuccessful attempt by members to militarily harmonize and work together effectively. The organization restructured itself for security and economic cooperation with the 1950 Joint Defense and Economic Cooperation Treaty. The latter served as a legal basis for the mandating of the 1961 Arab League Security Force in Kuwait.
