The Convention on International Civil Aviation, also known as the Chicago Convention, established the International Civil Aviation Organization (ICAO), a specialized agency of the United Nations charged with coordinating and regulating international air travel. The convention establishes rules of airspace, airplane registration and safety, and details the rights of the signatories in relation to air travel.
The document was signed on December 7, 1944 in Chicago, Illinois by 52 signatory states. It received the requisite 26th ratification on March 5, 1947 and went into effect on April 4, 1947. The convention has since been revised seven times (in 1959, 1963, 1969, 1975, 1980, 1997, and 2000). Links to all versions of the document can be found in the external links section.
The original signed document resides in the National Archives of the United States.
