4. Alliances Triple Alliance Italy Germany Austria Triple Entente Britain France Russia VS.

5. How did these alliances start? (Don’t write this. It’s too confusing.) • 1871 – Germany is a ‘satisfied power’ • Aimed now at keeping peace • France is biggest threat to peace • Try to isolate France by taking away allies • 1879 – Germany forms Dual Alliance • Germany • Austria-Hungary • 3 years later, Italy joins forming the Triple Alliance • 1881 – Germany signs treaty with Russia • taking another ally away from France. http://www.worldwar1.com/tlalli.htm#dual – For a complete timeline of all alliances

6. 1890 – new German leader allows treaty with Russia to lapse • Russia responds by forming an alliance with France • (just what Germany didn’t want) • Germany would be forced to fight from two sides • Germany starts building ships comparable to British ships

7. Britain reacts by forming an alliance with France • 1907 – Britain then makes another treaty with Russia and France, forming the Triple Entente • Britain was not bound to fight with France and Russia, but rather promised not to fight against them.

9. 1908 – Austria annexed Bosnia and Herzegovina • Serbia who had hoped to rule these provinces became upset. • Tension between Serbia and Austria grew… • Serbia continually vowed to take the land back • Austria continually vowed to crush any Serbian effort of the land… • Eventually the heir to the Austrian throne was killed by a Serbian nationalist…

10. This was the “trigger” that started it all… (Only write what is in bold print.) • June 1914 • Archduke Franz Ferdinand, Heir to the Austrio-Hungary throne and his wife shot dead while visiting the capital of Serbia. • Assassins were Serbian, • Austria used the assassinations as an excuse to punish Serbia. • Austria gave Serbia an ultimatum, in which Serbia only honored a few demands • Austria was upset with this and declared war on Serbia. • That same day Russian troops were ordered towards the Austrian border…. War was now inevitable.

11. The Spark At Sarajevo, Bosnia, on June 28, 1914, the Archduke Franz (heir to the throne of Austria-Hungary) Ferdinand and his wife, the Duchess Sophia, a Serbian nationalist assassin murdered the archduke, plunging Europe into war. Gavrilo Princip, who killed Archduke Franz Ferdinand

15. The French Plan XVII • Mass troops along the German/French border to repel attack. • Some troops arrived by bicycle to the front lines. • Several officers were sent home because of their lack of willingness to fight. • Completely ignored the threat of Germany advancing through Belgium. • Massive failure.

16. The French (continued)

17. In the fall of 1917, after the Bolshevik Revolution, Russia made a separate peace with Germany, dissolving the eastern front of the war. The French army was mutinous after the failure of a heroic attempt to create an offensive against the German trenches on the western front. Germany had decisively defeated Italian forces, and was preparing to mount a massive western offensive in the valley of the Somme.

19. Technology of killingThere were new weapons not being used efficiently because they weren’t completely understood.(Write the words in bold print for the next several slides.) Airplanes - of little importance in battle -for now…… Machine guns - very effective • Mow troops down, considered a ‘weapon of mass destruction’ Mustard Gas • Quickly became ineffective because of gas masks • Wind could blow gas back on aggressor

20. Planes • The early years of war saw canvas-and-wood aircraft used primarily to function as mobile observation vehicles. This was an improvement over the bullet-attracting Zeppelin and the immobile observation balloon. • Enemy pilots at first exchanged waves and later progressed to throwing bricks and other objects • (grenades and sometimes rope, which they hoped would tangle their enemy's propeller), which eventually progressed to guns. • Once the guns were mounted to their planes, the era of air combat began.

21. Helmets • patented in 1915 by the Briton John L. Brodie

22. Grenades Hand-held implement of destruction: Just throw it at what you want to go away

23. Chemical Warfare • Major distinguishing factor of the war. • Only a small portion of casualties were caused by gas • Caused blindness and death by choking • Harassment and psychological effects. • How do you fight back???? • Gas masks • HOWEVER:Wind could blow gases back at aggressor • (FAIL.)

24. Machine Guns • Machine guns and barbed wire responsible for greatest # of deaths • Guns now lighter and more mobile (Don’t write the next part) • BAR (Browning Automatic Rifle) • Gas operated • 16 to 19 lbs. • Semi or fully automatic

25. Tanks • Armored combat vehicle used mostly for crossing rough terrain and over barbed wire. • Introduced by the British in 1916 The name tank came when the British shipped them in crates marked "tanks“ trying to cover up what they really were Image - www.msu.edu/user/ storto/afvwwi.htm

26. Submarines / U-Boats • German (unterseeboot) • Primary targets: merchant convoys bringing supplies from the United States and Canada to Europe • Lusitania (most famous vessel sunk) Unrestricted Submarine Warfare – means you don’t have to give warning before destroying Image -- http://www.gwpda.org/naval/ub1-type.gif

33. Was the sinking of the Lusitania justified? • U.S. claimed the Lusitania carried innocent passengers and cargo. (Don’t write the next part.) • Lusitania was in fact heavily armed;* • 1,248 cases of shells • 4,927 boxes of cartridges (1,000 round/box) • 2,000 cases of small-arms ammunition *Information from Howard Zinn’s A People’s History of the United States

34. The Zimmerman Telegraph Coded message from Germany to Mexico promising a return of territories taken by the United States from Mexico over the past century IF Mexico enters the war against the United States.

35. FROM 2nd from London # 5747: "We intend to begin on the first of February unrestricted submarine warfare. We shall endeavor in spite of this to keep the United States of America neutral. In the event of this not succeeding, we make Mexico a proposal of alliance on the following basis: make war together, make peace together, generous financial support and an understanding on our part that Mexico is to reconquer the lost territory in Texas, New Mexico, and Arizona. The settlement in detail is left to you. You will inform the President of the above most secretly as soon as the outbreak of war with the United States of America is certain and add the suggestion that he should, on his own initiative, invite Japan to immediate adherence and at the same time mediate between Japan and ourselves. Please call the President's attention to the fact that the ruthless employment of our submarines now offers the prospect of compelling England in a few months to make peace." Signed, ZIMMERMANN

36. America Joins the Fight • Germany seeks to control Atlantic Ocean to stop supplies to Britain • Uses unrestricted submarine warfare - ships near Britain sunk without warning • NOW the war is global
