World War I at 100

Resources curated for the centennial of the start of the global conflict that reshaped the world.


On April 6, 1917, the United States formally entered World War I. While the direct involvement of the United States only lasted about a year, according to historian Jennifer Keene, it “quite simply shaped the world in which we live.”

At the centennial of the U.S. entrance into World War I, OAH curated a selection of sources including interviews, articles, and other content by member historians who study World War I.
