Crash Course: America in World War I

Introduction Imagine a world where the United States, the land of the free and the home of the brave, is at war with Germany, the land of beer and bratwurst. Sounds crazy, right? But that's exactly what happened in 1917, when America joined the Great War, also known as World War I.

The Core Idea America's entry into World War I was a turning point in the war, but also a turning point in American history. The US had been neutral for three years, but the sinking of the passenger ship Lusitania and Germany's resumption of unrestricted submarine warfare led to a shift in public opinion. President Woodrow Wilson, a self-proclaimed pacifist, eventually declared war on Germany, and the US military mobilized for the first time since the Civil War.
