Concept note-1: -On April 4, 1917, the U.S. Senate voted in support of the measure to declare war on Germany. The House concurred two days later. The United States later declared war on German ally Austria-Hungary on December 7, 1917.
Concept note-2: -April 6, 1917: Two days after the U.S. Senate voted 82 to 6 to declare war against Germany, the U.S. House of Representatives endorses the declaration by a vote of 373 to 50, and America formally enters World War I.
Concept note-3: -America 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.
Concept note-4: -In 1917, Germany’s attacks on American ships and its attempts to meddle in U.S.-Mexican relations drew the U.S. into the war on the side of the Allies. The United States declared war on Germany on April 6, 1917.
Concept note-5: -The entry of the United States was the turning point of the war, because it made the eventual defeat of Germany possible. It had been foreseen in 1916 that if the United States went to war, the Allies’ military effort against Germany would be upheld by U.S. supplies and by enormous extensions of credit.
