The International Civil Aviation Organization (ICAO)

Representatives of fifty-two States attending the International Civil Aviation Conference, which met in Chicago from 1 November to 7 December 1944, at the invitation of the Government of the United States, adopted a Convention providing for the establishment of the International Civil Aviation Organization (ICAO). The Conference also drew up an Interim Agreement providing for a Provisional International Civil Aviation Organization (PICAO) to operate until the formal establishment of the permanent organization. PICAO came into being on 6 June 1945, after twenty-six States had adhered to the Interim Agreement. ICAO came formally into existence on 4 April 1947, thirty days after the Convention on International Civil Aviation had been ratified by the required twenty-six States. The Convention superseded, as between contracting States, the provisions of two earlier agreements: the Paris Convention of 1919 establishing the International Commission for Air Navigation, and the Pan-American Convention on Commercial Aviation drawn up in Havana in 1928.
