7  Germany, France, & Great Britain are in a trench warfare stalemate in 1915  To break a stalemate at sea, Germany began to employ U-boats, submarine ships that traveled under water  short for Unterseeboot, the German word for submarine.  U-boats, traveling under water, could sink British supply ships with no warning.  When the British cut the transatlantic cable, which connected Germany and the United States, only news with a pro-Allied bias was able to reach America.  American public opinion was therefore swayed against Germany’s U-boat tactics.

8 U-Boats By 1918, Germans had sunk 6,500 allied ships.

10 The Sinking of the Lusitania  On May 7,1915, a German U-boat sank the British passenger liner Lusitania, which had been carrying both passengers and weapons for the Allies.  Since 128 American passengers had been on board, the sinking brought the United States closer to war. The Sussex Pledge  More Americans were killed when Germany sank the Sussex, a French passenger steamship, on March 24,1916.  In what came to be known as the Sussex pledge, the German government promised that U- boats would warn ships before attacking, a promise it had made and broken before.

13 Submarine Warfare  The leading cause of war for the U.S. is German unrestricted submarine warfare  On January 31, 1917, Germany announced its intent to end the Sussex pledge and return to unrestricted submarine warfare.  This action caused the United States to break off diplomatic relations with Germany.  Despite this announcement, the German navy did not attack any American ships in February, causing the United States to continue to hope for peace. The Zimmermann Note  During this time, Britain revealed an intercepted telegram to the government of Mexico from Germany’s foreign minister, Arthur Zimmermann.  In a telegram, known as the Zimmermann note, Germany offered to return American lands to Mexico if Mexico declared war on the United States.

15  The Great War was unpopular in Russia. However, Czar Nicholas II refused to back out.  They had lost over 1 million men; government was struggling to economically The Russian Revolution replaced Russia’s autocratic czar with a republican government in March 1917  After the Russian Revolution in March 1917 removed their autocratic government, The U.S. was more willing to join the Allies  This removed one more stumbling block to an American declaration of war.  Final Steps: Germany sinks 3 American ships in March (Memphis, Illinois, Vigilancia)  President Wilson declared that “the world must be safe for democracy.”  On April 6, 1917, the President signed Congress’s war resolution, officially bringing the United States into the war.
