The Arab League, composed of Egypt, Syria, Iraq, Lebanon, Transjordan, Saudi-Arabia, and Yemen, was established by the pact signed by these states on March 22, 1944. According to the pact, which may be regarded as the League's constitution, the League has as its purpose to strengthen relations between the member-states, to coordinate their policies in order to achieve cooperation between them, and to safeguard their independence and sovereignty. With due regard to the “organization and circumstances of each state,” cooperation is to be effected specifically on 1) economic and financial affairs: commercial relations, customs, currency, and questions of agriculture and industry; 2) communications: railroads, roads, aviation, navigation, telegraphs and posts; 3) cultural affairs; 4) nationality, passports, visas, extradition, and execution of judgments; 5) social affairs; and 6) health affairs.
