8. With a partner, compare and contrast nationalism and militarism. WWI Video

9. SO…Europe Goes to War! Let’s organize this information: Many European countries believe in militarism, so ALIKE countries form alliances. 2 Biggest Alliances  Allied Powers (Allies) Serbia, Russia, Belgium, and France  Central Powers Austria-Hungary, Germany  Cause: Serbian assassinated Archduke Ferdinand (Archduke=Austria-Hungary)  Effect: Austria-Hungary declared war on Serbia (Russia steps in to help Serbia; Germany steps in to help Austria-Hungary…  and also declares war on Belgium and France! World War I has begun!

10. World War I Has Begun! Soon all of Europe was at war! Germany and Austria-Hungary …Which side? Central Powers Russia, Great Britain, and France were allies and became the leaders of an alliance known as… The Triple Entente The conflict eventually involved nations around the world. Was now called WORLD WAR I Partners: Tell why it was known as WWI.

12. World War I At first, most US citizens wanted to stay out of the war. They believed it was Europe’s fight, not theirs President Woodrow Wilson won re-election in 1916 vowing not to get the US involved in the fighting. But…over time, a number of things happened that led the United States to enter the war…

13. LESSON 2

14. U-Boats and the Lusitania During WWI, Germany used U-boats. U-boats were submarines (ships that sail under water). Could stay hidden beneath the surface of the water as they fired torpedoes that sank ships German U-boats fired not only on enemy ships but also on ships from other countries Germany believed these ships were actually carrying goods meant to help the nations it was fighting. Here’s the problem…

15. U-Boats and the Lusitania Some of these ships carried US citizens! In May of 1915, German submarines sank a passenger ship called the Lusitania. Over 100 US passengers died! German submarines sank the Lusitania. ? People in the U.S. were FURIOUS!

16. U-Boats and the Lusitania In reality, the US government was secretly using the Lusitania and other passenger ships to sneak military supplies to Great Britain and its allies. To most people, however, Germany’s actions looked like an evil attack against innocent civilians. Public opinion started to change. More people in the US begin to favor war. What is your opinion? Do you think Germany had a right to sink the Lusitania? Discuss this with a neighbor.

19. The Most Destructive War in History At That Time Because of these new technologies: submarines, airplanes, mustard gas, armored tanks, hand grenades, etc. this was a highly destructive war! A concept called Trench Warfare was developed.

24. Lesson 3 Partner talk: What kind of things do you think the people at home could have done to help in the war?

25. Other Key Vocabulary Rations Propaganda Armistice Isolationism An island is isolated…so isolationism means far away, from other lands.

27. Problem: Soldiers needed supplies to fight in the war. Solution: Businesses and workers worked hard together to make supplies for the soldiers.

28. What does this have to do with economics? Turn to a neighbor and explain how this would affect supply and demand during this time period.

38. SUMMARIZER: With a partner, discuss the concepts of nationalism, militarism, imperialism, and isolationism.

39. The Roaring Twenties Building an army to fight in World War I meant that the nation needed weapons and supplies. Such production created jobs and high demand for products. As production and jobs increased, so did prosperity. After the war ended, most citizens just wanted to return to normal and enjoy the new wealth. The decade that followed the war became known as the Roaring Twenties.

41. The Jazz Age The first years of the 1920s were called the Jazz Age. Jazz was a new form of music that made its way from New Orleans to northern cities early in the decade. African American musicians created it. It is a style of music in which performers use brass, woodwinds, and percussion instruments to improvise (play without looking at notes) rather that rely on sheet music. The fast and spirited beat of jazz made it popular with both blacks and whites. Jazz led to the creation of several new dances in the 1920s. Trumpeter Louis Armstrong became one of the most famous jazz musicians in history during this period.

43. The Harlem Renaissance Another important movement among the African American community was the Harlem Renaissance. It involved black writers and artists. It was named for Harlem, New York, the mostly black community where it began. Langston Hughes became famous for his poems and stories of black life in America.

45. Henry Ford and the Automobile Early in the twentieth century, only a few people owned automobiles. Only the rich could afford to buy them. Then, a man named Henry Ford introduced the idea of mass producing cars. He wanted to make so many cars that he could afford to sell them cheaper and still make a profit. This would make Ford a lot of money and make it possible for common people to own an automobile. Ford introduced a new kind of assembly line.

46. Henry Ford and the Automobile An assembly line allows workers to focus on one task rather than trying to assemble the whole product. Each of Ford’s workers was responsible for assembling one part of each car. Earlier assembly lines required workers to walk from station to station. Ford’s brought the parts to the workers. His employees could stand in one spot while the parts came to them. This made the work much faster and increased production. Ford paid his employees $5 a day (a good salary back then) so that they could afford to buy his cars.

47. Henry Ford and the Automobile Henry Ford’s first mass-produced car was known as the Model T. It revolutionized the auto industry. Ford’s ideas about mass production and his assembly line helped make other businesses better as well.

49. American Heroes American heroes arose during the 1920s. One of the most popular was Babe Ruth. Ruth was a great baseball player. He played most of his career with the New York Yankees. Ruth became famous for his powerful hitting. Before he left the game, he became the all-time home run leader. His 714 homeruns stood as a record until 1974, when Atlanta Brave named Hank Aaron finally broke it. Babe Ruth still rank third on the all-time homerun leaders list.

51. American Heroes Charles Lindbergh also became a hero during this period. Lindbergh became the first person in history to fly a solo flight non-stop across the Atlantic Ocean. He flew from the United States to Paris, France, in 1927. Today, Lindbergh’s plane hangs from the ceiling of the National Air and Space Museum in Washington, D.C.
