This thesis is an examination of the relationship between the Ukrainian nationalists, led by Petliura (The Ukrainian People’s Republic) and both Germany and Poland in the period 1918-1922. Although the thesis addresses primarily the situation after World War I and the military collapse of Germany in Eastern Europe, I also examine the historical relationship between Germany and Ukraine, which came to the fore in the period of World War I, and especially following the treaties of Brest Litovsk. This period involved the German recognition of Ukrainian independence, and the German intervention in Ukrainian internal political and economic affairs.
