A new documentary explores how World War I forever changed America and the world. Premiering in conjunction with the 100th anniversary of America’s entry into the war on April 6, 1917, The Great War, from American Experience Films, will air on WHRO TV 15 on April 10-12 at 9 p.m. Drawing from unpublished diaries, memoirs and letters, The Great War tells the rich and complex story of World War I through the voices of nurses, journalists, aviators, and American troops who came to be known as “doughboys.” The series explores the experiences of African-American and Latino soldiers, suffragists, Native-American “code talkers,” and others whose participation in the war has been largely forgotten.

The Great War also explores how a brilliant PR man bolstered support for the war in a country hesitant to put lives on the line for a foreign conflict; how President Woodrow Wilson steered the nation through almost three years of neutrality, only to reluctantly lead America into the bloodiest conflict the world had ever seen, thereby transforming the United States into a dominant player on the international stage; and how the ardent patriotism and determination to support America’s crusade for liberty abroad led to one of the most oppressive crackdowns on civil liberties at home in American history. It is also a story of little known heroism and sacrifice (including the deadliest battle in American history) that would leave more than 53,000 men dead on the battlefield and more than 60,000 dead from disease. American fatalities would come at a critical time in the war, but they would be dwarfed by a cataclysm of violence that would ultimately claim 15 million lives.

“World War I was the soil from which so many things today really grew, starting with America’s place in the world,” said American Experience Executive Producer Mark Samels. “Before the war, America was isolated and uninvolved in world affairs. After the war, America stepped onto the world stage, and that continues today with our troops becoming involved in conflicts around the world. The current debate on the balance between national security and civil liberties also began with World War I. The debate over immigration reached its apex during World War I. The film is not only about what happened 100 years ago, but how what happened then transformed our nation and the world in ways still being felt today.”
