At the war’s onset, the United States maintained a strict foreign policy of neutrality. Americans had no appetite for intervention in a foreign war, and President Woodrow Wilson vowed to keep it that way. As the war progressed, however, events began to change public and political opinions. On May 5, 1915, a German U-Boat sank the British ocean liner RMS Lusitania. Of the nearly 1,200 passengers on board, 128 of them were American citizens. The Central Powers did not want the United States to enter the conflict, and Germany pledged that neutral ships and passenger vessels would be off-limits. However, in 1917, Germany resumed a policy of unrestricted submarine warfare. This, coupled with the famous Zimmermann Telegram (an intercepted German diplomatic cable proposing a military alliance with Mexico against the United States), pushed America into the war. In April of 1917, the US declared war on the German Empire, and by the end of the year, the Austro-Hungarian Empire as well. To finance America’s participation in the conflict, President Wilson turned to his Treasury Secretary, William Gibbs McAdoo. McAdoo had limited options in raising the needed revenues to finance the war, namely domestic bond sales and/ or changes in tax policy. Both options had strong support and opposition in various political circles. Ultimately compromise prevailed, and a combination of both policies was undertaken. Through a series of three Revenue Acts beginning in 1916, Congress raised individual and corporate tax rates. The lowest individual tax bracket went from a net income level of $20,000 and above in 1916 to a level of $5,000 and above by 1918. The highest tax rate paid on individual income jumped from 13% to 65% in the same period. Furthermore, corporate taxes increased and Congress implemented a Elsa Ruiz Great War were varied: the political assassination of Archduke Franz Ferdinand of Austria, colonial and territorial disputes involving the European powers and the difficult political landscapes of those very same nations. To be sure, the July Crisis of 1914, which resulted from the assassination of the Archduke (heir to the throne of the Austro-Hungarian Empire) by a Serbian was the match which began the conflagration. When the Kingdom of Serbia refused the politically untenable Austro-Hungarian ultimatums, war was declared. Two great alliances would face each other: the Allies, composed of the British Empire, France and Russia, and the Central Powers, composed of Germany and the Austro-Hungarian Empire. Other nations would soon entire the conflict, notably the Ottoman Empire joining with the Central Powers in late 1914, and Italy joining with the Allies in 1915. “For Victory, Buy More Bonds” Fourth Liberty Loan poster on view at the Museum of American Finance. www.MoAF.org  |  Summer 2015  |  FINANCIAL HISTORY  25
