THE POSTAL HISTORY OF ICAO

 

The growth of ICAO

 

On 6 June 1945, the required 26 States, including each of the 20 States elected to the Council, had accepted the Interim Agreement on International Civil Aviation. Thus, as per Article 1 - Section 1 of the latter Agreement, the Provisional Organization (PICAO) was born, within six months after the closing of the Chicago Convention.

 

On 5 March 1947, Spain was the 26th state to deposit, with the Government of the USA, its instrument of ratification to the Chicago Convention. Consequently, this Convention came into force on 4 April 1947 (i.e. 30 days later), among the states having thus ratified.

 

ICAO’s success is evidenced by the dynamic and sustained increases in the number of States adhering to its Convention on International Civil Aviation. The following table shows a summary of progress in terms of submitted instruments of ratification of this Convention.

 

However, two factors contributed largely to ICAO’s growth in terms of Member States:

  1. The emancipation in Africa, especially between 1960 and 1962. New countries were created by the decolonization; in a few years, 23 new States joined ICAO; and
  2. The breakup of the Socialist Federal Republic of Yugoslavia (in the 1990s) and the dissolution of the Soviet Union (starting from December 1991) led to the emergence of new States, which joined ICAO.

 

South Sudan became an independent state on 9 July 2011 and became the 191st member of ICAO on 10 November 2011, 30 days after South Sudan’s notification of adherence was received, on 11 October 2011.
