3. International Relations
The era between the two world wars was a period of complex interrelations among states and involved a variety of other institutions. The major dividing point in the two decades is the beginning of the Great Depression, which can be dated from the collapse of the New York stock market in 1929. The interwar period may be divided chronologically into two phases: (1) the postwar period of adjustment and building, and (2) the era of the Great Depression.  1
a. The Post–World War I Era
The main lines of development of international relations during the 1920s were to implement the Versailles Treaty, to organize international relations among the major powers in the changing global context, and to adjust to the globalization of many different types of activities.  2
Creation of the International Labor Organization and the International Commission for Air Navigation as a part of the development of the League of Nations organizational structures. Creation of the International Federation of Red Cross Societies, joining the various national societies into a single world federation.

Conflicts over borders of peace settlement (See 1919–22). Numerous disputes in Eastern Europe took place, contesting control of Vilna (between Poland, Lithuania, and Russia), Teschen (Poland and Czechoslovakia), Bergenland (between Austria and Hungary), Fiume (between Italy and Yugoslavia), and Upper Silesia (between Germany and Poland). In the Middle East, there was a Turco-Greek War (1919–22) for the control of Western Anatolia, which the new Turkish nationalist movement won, driving Greek forces completely out of Anatolia.  5
