The Convention on International Civil Aviation, which provided for the establishment of the International Civil Aviation Organization (ICAO), was signed in Chicago in 1944. The Organization came into existence on 4 April 1947 after 26 states had ratified the Convention.  Under article 44 of the Convention, the ICAO is charged with developing the principles and techniques of international air navigation, and fostering the planning and development of international air transport to ensure the safe and orderly growth of international civil aviation throughout the world.
