The spectacular fast developments in aircraft technology in the beginning of the 20th century, made law-making necessary in this new field of transportation, in peace and in war. In 1910 the first conference on an international air law code took place in Paris. International air law now deals with many topics, such transport responsibility, safety of passengers, airplanes and luggage, airport-regulations, hijacking, air pollution, and aerial warfare. The collection of international air law in the Peace Palace Library covers all the aspects of this (public and private) international law subject, including the historical part, the sources of international air law, the international organizations involved and the numerous international conventions: the Warsaw Convention 1929, the Montreal Convention 1999 and the Chicago Convention 1944 (one of the most ratified multilateral agreements currently in force, with 193 States Parties).
