The American entry into World War I came on April 6, 1917, after a year long effort by President Woodrow Wilson to get the United States into the war. Apart from an Anglophile element urging early support for the British, American public opinion sentiment for neutrality was particularly strong among Irish Americans, German Americans and Scandinavian Americans, as well as among church leaders and among women in general. On the other hand, even before World War I had broken out, American opinion had been more negative toward Germany than towards any other country in Europe. Over time, especially after reports of atrocities in Belgium in 1914 and following the sinking of the passenger liner "RMS Lusitania" in 1915, the American people increasingly came to see Germany as the aggressor.
