World War I: Lessons and Legacies explores the war and its lasting impact and far-reaching influence on American life.
Sparked by the assassination of one man, the war eventually included the forces of the world’s major industrial powers (over 18 countries) and ended with millions dead. World War I also gave rise to significant and enduring changes in America. Wartime technologies and medical advances resulted in new industries and novel ways to fight disease and treat disability. Women and minority participation in the war led to women’s voting rights and raised awareness on civil rights issues throughout society. The war led to pivotal changes in America’s culture, technology, economy, and role in the world. It redefined how we saw ourselves as Americans and its legacy continues today.
Developed for middle and high school students, the eight posters feature historical photographs, documents, graphics, educational text, and a design that reflects the modernity the war’s end brought to the 20th century.

World War I: Lessons and Legacies is organized by the Smithsonian Institution Traveling Exhibition Service and the National Museum of American History, in cooperation with the U.S. World War I Centennial Commission. It is funded in part by the Smithsonian Women’s Committee.

United States World War I Centennial Commission
The U.S. World War I Centennial Commission was created by an Act of Congress in 2013. Members of the Commission were appointed by the President, leaders of the Senate and the House of Representatives, and the American Legion, the Veterans of Foreign Wars, and the National World War I Museum. World War I remains America’s forgotten war, even though more Americans gave their lives during that war than during Korea and Vietnam combined, and even though it profoundly shaped the rest of “the American century.” The Commission will use the Centennial as a timely and essential opportunity to educate the country’s citizens about the causes, courses and consequences of the war; to honor the heroism and sacrifice of those Americans who served; and to commemorate through public programs and initiatives the centennial of this global event.

SI Women’s Committee
