World War II
2
Causes of World War II
  • -Resentment at the harsh peace of World War One
    fuelled the rise of Adolf Hitler. Anxious to
    avoid war, Britain and France chose to appease
    German territorial demands before finally
    'drawing a line in the sand' over Poland.
  • Political instability and economic devastation in
    Europe resulting from WWI
  • Worldwide depression
  • High war debt owed by Germany
  • High Inflation
  • Massive unemployment

    power is given to a dictator and individual
    freedoms are denied

German Advances
  • Germany invaded France and captured Paris.

15
  • Germany Bombed London in the Battle of Britain.
  • The British were able to turn away the Germans
    due to the invention of RADAR

16
Gradual change in American policy from neutrality
to direct involvement
  • 1. Isolationism
  • The U.S. refuses to join the League of Nations
    after WWI
  • The U.S. stays isolated during the Great
    Depression

17
2. Lend-Lease Act
  • The United States gave Britain war supplies and
    old naval warships in return for military bases
    in Bermuda and the Caribbean

18
War in the Pacific
  • Rising tension developed between the U.S. and
    Japan because of Japanese aggression in East Asia.

19

The Allies
  • Democratic nations (The United States, Great
    Britain, Canada) were known as the Allies.

    invaded by Germany
  • Allied leaders included
  • Franklin D. Roosevelt and later Harry S. Truman
    U.S.

  • Joseph Stalin Soviet Union

23
Turning point in the Pacific
  • The Battle of Midway, fought over and near the
    tiny U.S. mid-Pacific base at Midway atoll,
    represents the strategic high water mark of
    Japan's Pacific Ocean war.
  • Prior to this action, Japan possessed general
    naval superiority over the United States and
    could usually choose where and when to attack.
    After Midway, the two opposing fleets were
    essentially equals, and the United States soon
    took the offensive.

Turning point in Europe
  • In September 1943 a German army entered the city
    of Stalingrad and began fighting for the city.
    The main battle, The Battle of Stalingrad was a
    fierce struggle. Soldiers fought for each city
    block. In November 1942, more Soviet troops
    arrived and surrounded the German army. In late
    January 1943, with supplies running low, the
    remaining German troops in Stalingrad surrendered
    to the Soviet Union.

30
D Day
  • American and Allied troops landed in Normandy,
    France, on D-Day to begin the liberation of
    Western Europe.

31
End of War in Europe
  • Liberation of France (D-Day)
  • Liberation of Western Europe by the U.S., French,
    and British after D-Day
  • Death of FDR April 12, 1945
  • Liberation of Eastern Europe by the Soviets
  • Suicide of Adolph Hitler, April 30, 1945

32
End of War in The Pacific
  • Truman takes over as president.
  • Truman decides to drop the Atomic bomb on Japan.
  • Atomic Bomb will save American soldiers lives,
    but will cost many innocent women and children
    theirs.

33
Hiroshima
  • As many know, the atomic bomb has been used only
    twice in warfare. The first was at Hiroshima. A
    uranium bomb nicknamed "Little Boy" (despite
    weighing in at over four and a half tons) was
    dropped on Hiroshima August 6, 1945.
  • The Aioi Bridge, one of 81 bridges connecting the
    seven-branched delta of the Ota River, was the
    target ground zero was set at 1,980 feet. At
    0815 hours, the bomb was dropped from the Enola
    Gay. It missed by only 800 feet. At 0816 hours,
    in an instant, 66,000 people were killed and
    69,000 injured by a 10-kiloton atomic explosion.
  • The area of total vaporization from the atomic
    bomb blast measured one half mile in diameter
    total destruction one mile in diameter severe
    blast damage as much as two miles in diameter.
    Within a diameter of two and a half miles,
    everything flammable burned. The remaining area
    of the blast zone was riddled with serious blazes
    that stretched out to the final edge at a little
    over three miles in diameter.

34
Little Boy and Fat Man
  • After the Hiroshima bombing, President Truman
    announced, "If they do not now accept our terms,
    they may expect a rain of ruin from the air the
    likes of which has never been seen on this
    earth." Japan still refused to surrender.

35
Nagasaki
  • On August 9, 1945, Nagasaki fell to the same
    treatment. This time a Plutonium bomb nicknamed
    "Fat Man" was dropped on the city. Though "Fat
    Man" missed its target by over a mile and a half,
    it still leveled nearly half the city. In a split
    second, Nagasaki's population dropped from
    422,000 to 383,000. Over 25,000 people were
    injured.
  • Japan offered to surrender on August 10, 1945,
    ending WWII.
  • NOTE Physicists who have studied these two
    atomic explosions estimate that the bombs
    utilized only 1/10th of 1 percent of their
    respective explosive capabilities.

WWII on the Home Front
  • American involvement in WWII brought an end to
    the Great Depression. Factories and workers were
    needed to produce goods to win the war.
  • -Thousands of American women took jobs in
    defense plants during the war (e.g., Rosie the
    Riveter).

40
WWII Propaganda
  • What does this poster mean?
  • It is asking Americans to save gas by riding
    together.
  • Those that ride alone are helping the Germans win
    the war, by wasting fuel.

41
  • Why did this woman turn her bumpers into the
    scrap heap?
  • So they could be turned into weapons for the war.

42
Rationing
  • Americans at home supported the war by conserving
    and rationing resources.

44
Racial Barriers
  • The need for workers temporarily broke down some
    racial barriers (e.g., hiring in defense plants)
    although discrimination against African Americans
    continued.
  • Truman desegregated the Armed Forces

45
Internment Camps
  • While many Japanese Americans served in the armed
    forces, others were treated with distrust and
    prejudice, and many were forced into internment
    camps.
