International Refugee Organization
The International Refugee Organization (IRO) was an intergovernmental organization founded on 20 April 1946 to deal with the massive refugee problem created by World War II. A Preparatory Commission began operations fourteen months previously. In 1948, the treaty establishing the IRO formally entered into force and the IRO became a United Nations specialized agency.
