The First World War (WW1). Analyze the events that drew the United States into World War I

The assassination of Archduke Franz Ferdinand was the immediate cause of World War I. But the events that led to the Great War go further back into the nineteenth century. As with the Boxer Rebellion of 1900, nationalism, imperialism, and militarism all played a part.
Analyze how the forces of nationalism, imperialism, and militarism irrevocably led to World War I. Pay particular attention to the rise of Pan-Slavism in Eastern Europe and the corresponding rise of nationalism in German-speaking states. Analyze how the alliance system contributed to the ultimate outbreak of war.
Then analyze the events that drew the United States into World War I. Clearly discuss why America first remained neutral between1914-1917. What role did ethnicity play in America's neutrality? Then identify and analyze the specific events that led to America's entrance into the war. Evaluate America's contribution to the war effort and to what extent America's entry contributed to the end of the war. Finally, analyze the events that led to the defeat of the Treaty of Versailles. What effect did this have on America's role in the world during the 1920s and 1930s? Pay particular attention to the role of President Woodrow Wilson both during and after the war, in particular, his efforts to establish the League of Nations.
