American History Resources on War and Conflict


The early 20th century saw tensions rise across Europe, erupting in war after the death of the Archduke of Austria-Hungary in the summer of 1914. While initially left out of this war, the United States entered World War I in April of 1917 following attacks on passenger ships, most notably the RMS Lusitania, and an intercepted telegram between Germany and Mexico. World War I ended with the Armistice peace on the eleventh hour of November 11, 1918. These months of conflict saw many Americans sent to Europe where their experiences were detailed through letters, photographs, and other materials sent home to family members. This section will help direct research on the experiences of Americans both at home and abroad during this time period.
