U.S. Entry into World War I
History.com EditorsWhen World War I broke out across Europe in 1914, President Woodrow Wilson proclaimed the United States would remain neutral, and many Americans supported this policy of nonintervention. However, public opinion about neutrality started to change after the sinking of the British ocean liner Lusitania by a German U-boat in 1915; almost 2,000 people perished, including 128 Americans. Along with news of the Zimmerman telegram threatening an alliance between Germany and Mexico, Wilson asked Congress for a declaration of war against Germany. The U.S. officially entered the conflict on April 6, 1917.
World War I Begins
On June 28, 1914,
Archduke Franz Ferdinand, heir to the throne of the Austro-Hungarian Empire, and his wife, Sophie, were assassinated by a Bosnian Serb nationalist in Sarajevo, the capital of the Austro-Hungarian province of Bosnia and Herzegovina.
One month later, on July 28, Austria-Hungary declared war on Serbia. Within a week, Russia, France, Belgium, Great Britain and Serbia had sided against Austria-Hungary and Germany, and the Great War, as it came to be known, was underway.
Germany and Austria-Hungary later teamed with the
Ottoman Empire and Bulgaria and were referred to collectively as the Central Powers. Russia, France and Great Britain, the major Allied Powers, eventually were joined Italy, Japan and Portugal, among other nations.

On August 4, as
World War I erupted across Europe, President
Woodrow Wilson proclaimed America’s neutrality, stating the nation “must be neutral in fact as well as in name during these days that are to try men’s souls.”
With no vital interests at stake, many Americans supported this position. Additionally, the U.S. was home to a number of immigrants from countries at war with each other and Wilson wanted to avoid this becoming a divisive issue.
American companies, however, continue to ship food, raw materials and munitions to both the Allies and Central Powers, although trade between the Central Powers and the U.S. was severely curtailed by Britain’s naval blockade of Germany. U.S. banks also provided the warring nations with loans, the bulk of which went to the Allies.
The Lusitania Sinks
On May 7, 1915, a German submarine sank the British ocean liner
Lusitania, resulting in the deaths of nearly 1,200 people, including 128 Americans. The incident strained diplomatic relations between
Washington and Berlin and helped turn public opinion against Germany.
President Wilson demanded that the Germans stop unannounced submarine warfare; however, he didn’t believe the U.S. should take military action against Germany. Some Americans disagreed with this nonintervention policy, including former president
Theodore Roosevelt, who criticized Wilson and advocated for going to war. Roosevelt promoted the Preparedness Movement, whose aim was to persuade the nation it must get ready for war.
In 1916, as American troops were deployed to
Mexico to hunt down Mexican rebel leader
Pancho Villa following his raid on Columbus,
New Mexico, concerns about the readiness of the U.S. military grew. In response, Wilson signed the National Defense Act in June of that year, expanding the Army and the National Guard, and in August, the president signed legislation designed to significantly strengthen the Navy.
After campaigning on the slogans “He Kept Us Out of War” and “America First,” Wilson was elected to a second term in the
White House in November 1916.
Meanwhile, some Americans joined the fighting in European their own. Starting in the early months of the war, a group of U.S. citizens enlisted in the French Foreign Legion. (Among them was the poet Alan Seeger, whose poem “I Have a Rendezvous with Death” later was a favorite of President
John F. Kennedy. Seeger was killed in the war in 1916.) Other Americans volunteered with the Lafayette Escadrille, a unit of the French Air Service, or drove ambulances for the American Field Service.
Germany’s U-Boat Submarine Warfare Resumes
In March 1916, a German U-boat torpedoed a French passenger ship, the Sussex, killing dozens of people, including several Americans. Afterward, the U.S. threatened to cut diplomatic ties with Germany.
In response, the Germans issued the Sussex pledge, promising to stop attacking merchant and passenger ships without warning. However, on January 31, 1917, the Germans reversed course, announcing they would resume unrestricted submarine warfare, reasoning it would help them win the war before America, which was relatively unprepared for battle, could join the fighting on behalf of the Allies.
In response, the U.S. severed diplomatic ties with Germany on February 3. During February and March, German U-boats sank a series of U.S. merchant ships, resulting in multiple casualties.
The Zimmerman Telegram
Meanwhile, in January 1917, the British intercepted and deciphered an encrypted message from German Foreign Minister Arthur Zimmermann to the German minister to Mexico, Heinrich von Eckhart.
The so-called
Zimmerman telegram proposed an alliance between Germany and Mexico—America’s southern neighbor—if America joined the war on the side of the Allies.
As part of the arrangement, the Germans would support the Mexicans in regaining the territory they’d lost in the Mexican-American War—
Texas, New Mexico and
Arizona. Additionally, Germany wanted Mexico to help convince Japan to come over to its side in the conflict.
The British gave President Wilson the Zimmerman telegram on February 24, and on March 1 the U.S. press reported on its existence. The American public was outraged by the news of the Zimmerman telegram and it, along with Germany’s resumption of submarine attacks, helped lead to the U.S. to join the war.
The U.S. Declares War on Germany
On April 2, 1917, Wilson went before a special joint session of Congress and asked for a declaration of war against Germany, stating: “The world must be made safe for democracy.”
On April 4, the Senate voted 82 to 6 to declare war. Two days later, on April 6, the
House of Representatives voted 373 to 50 in favor of adopting a war resolution against Germany. (Among the dissenters was Rep.
Jeannette Rankin of
Montana, the first woman in Congress.) It was only the fourth time Congress had declared war; the others were the
War of 1812, the War with Mexico in 1846 and the
Spanish-American War of 1898.
In early 1917, the U.S. Army had just 133,000 members. That May, Congress passed the
Selective Service Act, which reinstated the draft for the first time since the
Civil War and led to some 2.8 million men being inducted into the U.S. military by the end of the Great War. Around 2 million more Americans voluntarily served in the armed forces during the conflict.
The first U.S. infantry troops arrived on the European continent in June 1917; in October, the first American soldiers entered combat, in France. That December, the U.S. declared war against Austria-Hungary (America never was formally at war with the Ottoman Empire or Bulgaria).
When the war concluded in November 1918, with a victory for the Allies, more than 2 million U.S. troops had served at the Western Front in Europe, and more than 50,000 of them died.

LM - please read the last paragraph under WW! Begins, and just above The Lusitania Sinks.
Made easy for you.
It is very clear the bulk of American aid prior to entry into WW! went to England.
Also - it has become clear the Lusitania carried armaments for England.
Submitted for One's edification.
Ignorance is simply the lack of knowledge - it is curable with education.
Stupidity is only curable with a bullet to the brain.
