9 Alliances are Formed Triple Entente (Allies) - Britain, France, and Russia Triple Alliance (Central Powers) – Germany Austria-Hungary Italy LloydGeorgeBritain Georges Clemenceau France Czar Nicholas II Russia Kaiser Wilhelm II Germany Franz Joseph Austria- Hungary VittorioOrlandoItaly

13 The United States and WWI Up until 1917, the U.S. remained neutral in the war. Woodrow Wilson was the President of the U.S. during WWI. Wilson was re-elected and would serve until The U.S. Enters World War I! 5 Reasons why the U.S. entered WWI? 1. Neutrality Rights Violations - President Wilson warned Germany to respect our neutrality rights on the open seas, but they continued to attack and sink our ships. Sussex Pledge (1916)- After a German U-Boat sank a French passenger ship, the Sussex, in the English Channel injuring several Americans, Wilson threatened to break Neutrality. Germany pledged not to attack merchant vessels without warning, but they would not honor this pledge.

14 2. Sinking of the Lusitania - A British passenger ship was sunk by a German U-Boat killing 1,200 people, including 128 Americans.

15 3. The Bolshevik Revolution of Czar Nicholas II of Russia is overthrown by the Bolshevik (Communist) Party led by Vladimir Lenin. Lenin will soon make peace with Germany and pull out of the war.

16 4. Allies Plea - for help from the U.S., because Britain and France need assistance. 5. Zimmerman Telegram - A secret telegram sent by the German foreign minister Arthur Zimmerman to Mexico in 1917 urging Mexico to attack the U.S. if they got involved in WWI. The telegram was intercepted by the British and given to President Woodrow Wilson.

17 The Yanks are coming… The United States Enters the War Neutrality collided with three realities: Ethnic ties with EuropeEthnic ties with Europe U.S. economic links with the AlliesU.S. economic links with the Allies Pro-allied sympathiesPro-allied sympathies Wilsons desire to play a role in postwar Europe settlements.Wilsons desire to play a role in postwar Europe settlements. 1. Theodore pushed Wilson to go to war. He supported the National Security League – pushed to build up our Arms and military and prepare for war. 2. Carrie Chapman Catt, Jane Addams, and other feminists formed the Womans Peace Party supporting isolationism. 3. Wilsons Sect. of State, William Jennings Bryan resigned in 1915 because he opposed Wilsons changing views toward interventionism.

18 The United States declares war on Germany on April 6, 1917! President Wilson issues a Conscription (draft) for all men ages He later changes it to John Black Jack Pershing is chosen as commander of the American infantry nicknamed the doughboys. In June, 1917, about 200,000 doughboys are sent to France, but they were not ready for combat.

19 How World War I Comes to an End! Russia signs the Brest-Litovsk Peace Treaty with Germany pulling out of the war. Russia gave up large territories of land to Germany - Finland, Poland, Ukraine, and the Baltic States. Austria-Hungary surrendered to the Allies in November of Germany loses the Western Front The help of the eager-for-action U.S. doughboys against the low-morale German troops forced them to surrender to end the war on 11/11/11 – Armistice Day.

20 Wilsons 14 Points A plan drawn up by W.Wilson that included 14 specific strategies for ending the war and making peace. Was very lenient on conquered countries. Wanted to establish a League of Nations to oversee and enforce the terms of surrender. 1. It would be an international organization with the purpose of preserving peace throughout the world. 2. Every nation would have an equal vote. 3. Every nation in the world would be a member, and each nation would have an equal vote. 4. Any controversy within the League would be turned over to the Central Council: France, Britain, Italy, Japan, the U.S., and five small nations.

21 Treaty of Versailles Wilson would negotiate the treaty in Paris without much input from the new majority Republican Congress. France and Britain would not approve most of Wilsons 14 Points. They felt that they were too lenient. The League of Nations was approved to enforce the terms of the surrender. It was signed in Paris, France on June 28, 1919 officially ending WWI. The U.S. Congress did not approve of the treaty or the League of Nations, so they refused to sign it. Why? Because they felt that it did not benefit the U.S. 1. A group of thirty-nine Republican senators led by Henry Cabot Lodge opposed the League of Nations, citing several flaws in its structure. - Reservationists (Lodge) - willing to pass the treaty if changes are made. - Irreconcilables - no treaty, no way! 2. The Senators believed that the U.S. should remain isolationist after the war.

22 3. In March of 1920, the Senate defeated the vote for approval of the Treaty of Versailles and the League of Nations. Reasons Why? - Upset with Wilson for not including them in making the treaty. - Fear of involvement on war without Congressional declaration of war. - Fear of foreign control of military decision-making. - Questioned using War to prevent War. - The refusal of Wilson to compromise on Article X (ten) - it made members promise to protect each others territorial integrity against aggressors. Congressmen did not want to be pulled into foreign conflicts. Results of the Treaty of Versailles A. Kaiser Wilhelm II (German leader) was forced to give up his throne and he fled to Holland for the next 23 years. B. Germany had to pay back $30 Billion in war reparations. C. Germany had to break up all Alliances with other countries. D. Germany had to admit to a Guilt Clause. E. Created a League of Nations. F. Italy gained very little, refused to sign a treaty. G. Germany establishes a Republican form of government.
