​World War II 1939-1945

Important Ideas

Important Ideas

•Conditions in Europe after World War I were favorable to the rise of dictatorships. The Russian
Revolution Jed to the world's first Communist state in the Soviet Union (U.S.S.R.). The dissolution
of the German and Austro-Hungarian Empires led to the creation of fragile new democracies in
other parts of Europe.

•Benito Mussolini formed the Fascist Party, which took power in Italy in 1922. Adolf Hitler took
power in Germany in 1933 after the high unemployment caused by the Great Depression. These new
dictatorships glorified violence, obedience to leaders, and extreme nationalism. They arrested,
imprisoned and often killed their opponents. Hitler's Nazi Party condemned Jews and others.

•Hitler had an expansionist foreign policy. He re-armed Germany, helped Spanish dictator Francisco
Franco, annexed Austria, and demanded the Sudetenland in Czechoslovakia in 1938. The League of
Nations failed to stop aggressors. British and French leaders gave in to Hitler's demands in an
attempt at appeasement. Hitler took the rest of Czechoslovakia, and then demanded part of Poland
in 1939. This time, British and French leaders refused to give in. After signing a non-aggression pact
with Stalin, Hitler attacked Poland, starting World War II in Europe. In Asia, Japanese military
leaders had already occupied Manchuria in 1931 and had invaded eastern China in 1937.

•The German army developed a new form of offensive warfare-- the Blitzkrieg. Rapid coordinated
movements of airplanes, tanks, mechanized troop carriers and infantry made it possible to advance
at rapid speed. Germany quickly conquered Poland, defeated France, and controlled most of Europe
by 1940. In 1941, Germany violated its non-aggression pact and invaded the U.S.S.R..

•Americans at first tried to stay neutral in the war. After World War I, there had been a return to
isolationism. Congress passed the Neutrality Acts, prohibiting Americans from traveling on ships of
nations at war, or selling arms to nations at war. They could only sell non-military goods on a "cash-
and-carry" basis.

Important Ideas

•President Roosevelt was concerned at the rise of totalitarian states and the threat it presented to
democracy. When Japan attacked China in 1937, he proposed that peaceful states quarantine
aggressive nations. American volunteers also formed the Flying Tigers, a squadron of airplanes that
helped keep supply lines to China open. After Germany occupied France, Congress passed the first
peace-time draft. In 1941, Congress passed the Lend-Lease Act in order to sell, rent or lend wartime
equipment to Britain, which stood alone in facing the terror of Nazi Germany. In 1941, Roosevelt
met Churchill and they agreed to the Atlantic Charter, laying the foundation for the future U.N..

•Surprisingly, events in Asia rather than Europe brought the U.S. into the war. Roosevelt threatened
an embargo to force Japan to give up some of its conquests. Japanese leaders wanted to seize
Indonesia for its oil. On December 7, 1941, Japanese planes launched a surprise attack on the U.S
fleet at Pearl Harbor. The next day Roosevelt asked for a declaration of war against Japan.

•To pay for the war, the federal government sold war bonds. Factories converted from peacetime to
wartime production. The government rationed food and other goods so that it had a sufficient
supplies for armed forces overseas. Many Americans planted Victory Gardens to grow their own
fruits and vegetables. The Office of War Information controlled radio broadcasts, made posters and
newsreels, and tried to promote unrest in Germany, Italy and Japan. Women and minorities filled in
the workforce for men overseas, and some women enlisted in the WACS, or Women's Army Corp.
Tens of thousands of Japanese Americans were forcibly moved to internment camps as a result of
Executive Order 9066. In 1944, the U.S. Supreme Court upheld the order in Korematsu v. U.S.

•Large numbers of men enlisted in the armed forces, and others were drafted. African Americans were
restricted to segregated units and kept from combat until later in the war. The Tuskegee Airmen were a
group of African-American pilots who served as bomber escorts. In the Battle of the Bulge, African-
American units were used for combat. Vernon Baker was awarded the Medal of Honor 52 years after he had
heroically faced combat in Europe.

Important Ideas

•Because Nazi Germany was the greater threat, Roosevelt focused on the war in Europe first. Stalin
wanted the allies to open a second front in Western Europe, but the British felt the Americans were
not prepared. American and British forces landed in North Africa in 1942 and moved to Sicily and
Italy in 1943. General George Patton was one of the most successful U.S. commanders. General
Dwight Eisenhower commanded the invasion of Normandy, known as D-Day. Allied troops
advanced rapidly through France and retook Paris, but were surprised when Germany
counterattacked at the Battle of the Bulge. After the German attack collapsed, Allied troops crossed
into Germany.

•The end of the war came when Soviet troops invaded Germany from the east and the other Allies
from the west. Hitler committed suicide in 1945. U.S. troops were shocked when they liberated the
concentration camps and found the survivors of Hitler's attempt to exterminate Jews and others in
the Holocaust.

•The U.S. also fought Japan in the Pacific in this multiple-front war. After Pearl Harbor, Japan took
several Pacific Islands. U.S. and Filipino prisoners of war were forced on the Bataan Death March.
The tide in the Pacific turned in 1943 when the U.S. Navy, commanded by Admiral Chester Nimitz,
defeated a Japanese fleet at the Battle of Midway. Under General Douglas MacArthur, U.S. troops
gradually retook the Pacific through the strategy of "island-hopping,'' eventually reaching close to
Japan's home islands.

•President Harry Truman decided to use the new atomic bomb against Japan. After bombs were
dropped on Hiroshima and Nagasaki in August 1945, Japan surrendered. World War II. in which
over 70 million people died. was over.

•The war ended with the rise of two Superpowers- the U.S. and the U.S.S.R.. Germany and Japan
were occupied by allied troops. and their leaders were tried for war crimes. Germany was divided
into four occupation zones.

Return to Isolationism

•After World War I, Americans had returned to
their traditional policy of isolation. They were
more concerned with events at home than abroad.
They felt safe behind the oceans separating them
from Europe and Asia. They raised tariffs,
restricted immigration, and even insisted that
their wartime allies, France and Britain, pay back
the war debts owed to Americans.

•There were notable exceptions to this trend
towards isolationism. In 1921, President Harding
hosted the Washington Naval Conference, in
which leading world powers agreed to limit the
size of their navies. ln 1928, the U.S. also
promoted the Kellogg-Briand Peace Pact,
signed by 62 nations, renouncing the use of war.

•Presidents Herbert Hoover and Franklin D.
Roosevelt both also tried to improve U.S. relations
with Latin America. Under the "Good Neighbor
Policy," the U.S. agreed not to interfere in the
internal affairs of Latin American nations, and
relations between the U.S. and the countries of
Latin America began to improve.

​The Causes of World War II

in Europe

1. The Rise of Dictators

3. The failure of the League of Nations

4. Appeasement Talks with Germany Fail

5. Germany invades Poland

​1. The Rise of Dictators in Europe

1930's

Rise of Dictatorships

•World War I and the Great Depression had
profound effects on Europe, just as they did
on the U.S.. Within two decades, Europe
was again at war.

•After the Russian Revolution of 1917,
Russia became the world's first Communist
state, known as the U.S.S.R.. In the 1920s,
Joseph Stalin seized power by eliminating
his adversaries. Stalin established a brutal
totalitarian dictatorship.

•In other parts of Europe, new democracies
were established but stood on shaky
foundations. Many conservatives feared the
rise of Communism and despised
democracy. They also held extreme
nationalist, racist, and anti-Semitic views.
Veterans from World War I had been
exposed to the inhumanity of trench
warfare, and violence became a part of
political life in the years after the war. In
Japan, military leaders assumed power with
the support of the Japanese Emperor.

Rise of Dictatorships

• New political parties like the Italian Fascists and German National Socialists

(Nazis) took advantage of these fears and emotions. In Italy, Benito Mussolini
developed a new type of political party and seized power soon after the war. The
spread of the Great Depression in the early 1930s led to high levels of
unemployment and shook public confidence in the new democratic Weimar
Republic, bringing Nazi leader Adolf Hitler to power in Germany. Hitler
established a dictatorship as brutal or worse than Stalin's. He was determined to
achieve German domination of Europe. Nazi aggression would be the main cause
for the outbreak of World War II.

​2. The Failure of the League

of Nations

Failure of the League of Nations

• The League of Nations, charged with

preventing another war, was too weak to
resist these dictators. The idea of
collective security -- that peaceful
nations would band together to stop
aggressors -- failed when countries like
the U.S. and the U.S.S.R. failed to become
members of the League. Germany and
Japan left the League in the 1930s. The
League did nothing to prevent Hitler from
rebuilding the German army, Italy from
attacking Ethiopia, Germany from
bombing cities in Spain, or Japan from
invading Manchuria and China.

3. ​Appeasement Talks Fail

Appeasement Fails

• Hitler had promised to expand Germany. In 1938, Hitler annexed Austria. Next,

he demanded the Sudetenland-- a part of Czechoslovakia where many Germans
lived. At first, France and Britain promised to protect Czechoslovakia, but when
Hitler threatened war, they backed down. At the Munich Conference (1938),
British and French leaders, without consulting the Czechs, agreed to give Hitler
part of Czechoslovakia to avoid war. This policy of giving in to satisfy the demands
of a potential enemy is sometimes known as appeasement. England and France
hoped to achieve peace through compromise, but failed. Hitler became convinced
that Britain and France were weak, and decided to make more demands.

​4. Germany invades Poland

German Invasion of Poland

•In 1939, Hitler made new territorial demands in Poland. Fearing Hitler intended to dominate
Europe, Britain and France refused to give in. Hitler responded by signing a nonaggression
pact with Stalin, in which the two secretly agreed to invade and divide Poland. When
Germany invaded Poland in September 1939, Britain and France declared war on Germany.
World War II had begun.

•In Poland, the German army unveiled a new type of warfare - the Blitzkrieg - which consisted
of rapid, coordinated movements by airplanes, tanks, troop carriers, and infantry. The
Germans quickly defeated the Poles, and before long they had also defeated the French and
taken over much of Europe. While the main advantage in battle in World War I had been
with the defense, the use of airplanes, tanks and mechanized transport brought the
advantage in warfare back to the offense during World War II. The Germans, and later the
Allies, also bombed civilians in cities to increase the terrors of war.

​The United States joins WWII 1942

America Goes to War

•In the early 1930s, Americans were too absorbed
with recovering from the Great Depression to be
very involved in affairs overseas. As tensions in
Europe rose, Congress passed a series of laws to
keep the country out of war. Americans had been
drawn into World War I when German submarines
had attacked American ships. To avoid similar
events, the Neutrality Acts (1935 -1937) prohibited
Americans from traveling on the ships of nations at
war. Americans were also prohibited from selling
arms to countries at war. Americans could sell
nonmilitary goods to Britain and other nations
opposed to aggression, but only on a "cash-and-
carry" basis.

•When Japan invaded China in 1937, President
Roosevelt delivered his "Quarantine" Speech. He
warned Americans of the growing unrest in the
world and told them that peaceful nations had to act
together to quarantine (isolate) aggressive nations.

•Roosevelt encouraged democratic nations to boycott
aggressors. Most Americans, however, remained
opposed to U.S. military action in either Europe or
Asia.

America Goes to War

•Not wishing to see all of China fall to Japan, the British used the Burma Road to send
supplies. When this 700-mile route was cut off, a group of American volunteer fighter
pilots, known as the Flying Tigers, were recruited to send supplies and to engage in
combat with Japanese pilots. These pilots destroyed almost 300 Japanese aircraft. Their
abilities as pilots made possible stirring victories when early news stories in the U.S. were
mostly filled with reports of Japanese forces advancing in the Pacific.

•Even after 1939, Americans still hoped to avoid involvement in the war, but they began
making preparations just in case they were dragged into the conflict. Congress increased
spending on the army and navy, and enacted the first peacetime draft. Roosevelt also took
the unusual decision of running for a third term - the first and last President to do so.

•In 1941, Roosevelt proposed the Lend-Lease Act to sell, lease, or lend war materials to
"any country whose defense the President deems vital to the defense of the U.S..“
American battleships began protecting British ships crossing the Atlantic with supplies for
Britain.

•The same year, Roosevelt told Americans he hoped to establish a world based on "Four
Freedoms": freedom of speech and expression, freedom of religion, freedom from want,
and freedom from fear. Later in 1941, Roosevelt met with British Prime Minister Winston
Churchill aboard a U.S. warship in the Atlantic. Roosevelt and Churchill announced that
their countries sought no territorial gains, freedom of the seas, and an end to war. They
signed the Atlantic Charter, laying the foundation for the later United Nations.

America Enters the War

•President Roosevelt believed that U.S. entry into
the war was inevitable. If Hitler defeated Britain,
many feared he would later attack the U.S.. In
1941, armed American merchant ships were
authorized to carry supplies directly to Britain. It
seemed that U.S. involvement in the war was only
a matter of time.

•Surprisingly, events in Asia, not Europe, finally
brought the U.S. into the war. Just as German
ambitions had triggered the war in Europe,
Japan's aggressive designs led to war in Asia.

•Japan's late 19th century industrialization had
been remarkably successful. But Japanese leaders
needed raw materials and markets for their
industries. They also wished to replace European
imperialism in Asia with the imperialism of an
Asian power. Japan's military began to influence
Japanese national policy. In 1931, Japan invaded
Manchuria. In 1937, Japan attacked the rest of
China. When Japan occupied southern Indochina
in 1941, Roosevelt reacted by freezing Japanese
assets in the U.S. and cutting off all trade with
Japan. Roosevelt offered to resume trade only if
Japan withdrew from China and Indochina.
Japanese leaders refused.

War in Europe

•Although the Japanese had attacked
Pearl Harbor, President Roosevelt
decided to focus American energies
on defeating Germany first. By the
time the Americans entered the war,
Hitler was in control of most of
Europe and North Africa. Hitler
made his greatest mistake when he
invaded the U.S.S.R. in June 1941
and declared war on the U.S. before
defeating Britain. By late 1941 , the
rapid German advance into the
U.S.S.R. was stopped just short of
Moscow. Roosevelt and Churchill
promised Stalin they would open a
second front against Germany in the
West, to relieve pressure on the
Soviet army.

Allies Invade France & Germany

•By 1944, the Germans suspected that the Allies would attempt an invasion of France. On June 6,
1944 D-Day -- 156,000 Allied troops under the command of General Dwight Eisenhower began
the invasion by landing at five beaches on the northwest coast of France at Normandy. Eisenhower
selected General Omar Bradley to lead the first American army to land in France. Prior to the
landing, Allied planes attacked Nazi forces. Then the largest amphibious operation up until that time
took place as landing craft carried thousands of Allied troops to the beaches of Normandy.

•After the landing, the Allies began moving eastward liberating Paris in August 1944. However, the
Allies advanced so quickly they were caught by surprise when Germans counter-attacked in the
Battle of the Bulge in December 1944. After this German attack collapsed, Allied troops crossed
the Rhine River and General Bradley pushed his troops for the final offensive into Germany.
American, British, and Free French forces led the invasion into Germany from the west, while Soviet
forces entered from the east. In May 1945, the Soviets captured Berlin. Rather than be taken
prisoner, Hitler committed suicide and Germany surrendered. The Soviets had sustained the greatest
losses in the conflict. More than 20 million Soviet soldiers and citizens had been killed in the war.

​Americans contribute to the War effort at Home

Paying for the War

•The U.S. government now faced the giant
task of mobilizing American manpower and
production to meet its enormous wartime
needs. The demand for labor for the war
effort brought an end to the lingering effects
of the Great Depression.

•To raise the enormous amounts of money
needed to pay for the war, the government
issued War Bonds and encouraged citizens to
buy them. The sale of war bonds also reduced
the amount of currency in the economy,
helping to keep inflation rates down. During
World War II, 85 million Americans bought
bonds, bringing $185 billion into the federal
treasury. In the end, the war cost $350 billion
- ten times the cost of World War I. World
War II marked a shift for the U.S. as it
changed from a creditor to a debtor nation.

•The successful sale of war bonds also
illustrated the high level of volunteerism
during the war -- the willingness of millions
of Americans to help in the war effort.

Industrial Production & Rationing

•U.S. industries switched rapidly from
peacetime to wartime production. Automobile
factories converted to making tanks. Special
advisory boards managed the war economy.
They instituted rationing to control the use of
raw materials. Americans were asked to
conserve anything that could be used in the
war effort. Rationing regulated the amount of
goods that a consumer could obtain. It was
introduced to avoid public anger over
shortages and to share in the sacrifices of war.

•The government rationed essential goods like
food, coffee, tires, gasoline, and even clothing.
Ration coupons were issued to each family,
based on its size. Americans were generally
happy to help in the war effort in order to
bring their loved ones home safely. The draft
and the expansion of industrial production
finally brought an end to the high
unemployment of the Great Depression.
Women, African Americans, and other
minorities filled the gap as other workers went
to fight the war.

Victory Gardens

• During the war, Americans also planted

Victory Gardens. These vegetable
gardens helped to make sure that an
adequate food supply was available for
both troops and civilians. The gardens
helped people in rural and urban
neighborhoods grow their own food for
their families, making more of the food
raised by farmers available to the
government for shipment to American
soldiers overseas.

Women in the Work Force

• For many women in America, World

War II brought not only sacrifices, but
also new jobs, new skills, and new
opportunities. Although prevented from
enlisting in the regular armed forces,
women joined the new Women's Army
Corps, or WACS, in large numbers.
After basic training, most of these
women took clerical jobs in the military.

• In civilian life, many women replaced

jobs formerly held by men, such as in
shipbuilding and aircraft production.
The idea was to have women fill jobs
formerly held by men so that more men
could be sent into combat. Songs like
Rosie the Riveter celebrated women's
new roles, although some private
contractors still refused to hire women.
Between 1941and 1945, more than 6.5
million women entered the work force.

Office of War Information

•A primary focus of the federal government
during the war was control of the content and
imagery of war messages. In 1942, the
President created the Office of War
Information (OWI). Among its wide-ranging
responsibilities was the production of pro-
Allied, anti-Axis propaganda, such as movies
and posters, to make citizens aware of how
they could help in the war effort. The OWI
produced its own radio programs, released its
own newsreels, and required that all movies
produced during the war contribute in some
way to the war effort. OWI messages asked
citizens to contribute time and money, to
create products, to conserve resources, and to
donate to the war effort in personal ways. The
OWI also started the Voice of America during
the war, sending messages overseas. The OWI
tried to stir up distrust of German, Italian and
Japanese leaders, to lower the morale of
enemy troops and populations, and to
encourage their surrender.

​The Contributions of Ethnic Minorities during World War II

Ethnic Minorities: African Americans

•Like women, members of minorities filled the
workforce to replace men sent overseas. Many
worked in war industries and government
agencies. African American soldiers also played
a significant role in World War II. More than
two and a half million registered for the draft, of
whom one million eventually served, even
though they were forced to serve in segregated
units. African Americans had to battle on two
fronts: the enemy overseas and prejudice at
home.

•African-American leaders demanded and finally
obtained permission to form all-black combat
units. The Tuskegee Airmen were an African-
American fighter group in the Air Corps. Their
main job was to provide escorts for pilots on
bombing missions. They performed so well in
combat that bomber groups often specifically
requested their support. By 1944, the army had
come under pressure to allow African Americans
to engage in combat on the ground and also
formed an African American infantry division.

Ethnic Minorities

• Native Americans:

▫ Native Americans enlisted for military

service in higher proportions than any
other minority group. More than
25,000 served in combat during the
war. Nearly 40,000 Native American
men and women left their
reservations for the first time to work
in defense industries.

• Mexican Americans:

▫ During the war, Mexican Americans

served in both the army and navy, and
fought in all of the major campaigns.
Despite this, Mexican Americans,
especially in California, continued to
face segregated housing, high
unemployment, and low wages.

​The War in the Pacific

Japan Prepares a Surprise Attack

•Japanese military leaders decided to attack Indonesia
to obtain oil for their war effort. Realizing such a
move would bring America into the war, they decided
to attack first. Japanese leaders believed a surprise
attack would catch the Americans unprepared,
temporarily eliminate U.S. naval power from the
Pacific, and allow Japan to fortify its positions in the
Pacific. The Japanese assumed that before the U.S.
could recover from this surprise blow, Japan would be
able to achieve all of its objectives in East Asia and the
Pacific.

•Japanese leaders also believed that Americans would
soon tire of the war and negotiate a compromise
peace -- leaving Japan in control of East Asia. On the
morning of December 7, 1941, two waves of Japanese
airplanes attacked the U.S. Pacific fleet stationed in
Pearl Harbor, Hawaii. The Japanese attack sank or
severely damaged 18 U.S. ships. On the airfields, more
than 260 airplanes were damaged or destroyed, while
the attack killed or injured almost 6,000 Americans .

•Four days later, Germany and Italy, allies of Japan,
declared war on the U.S.. Americans were now
engaged in a war on two fronts-- the Atlantic and
Pacific .

Forced Relocation of Japanese Americans

•The attack on Pearl Harbor created fear among many Americans, especially along the West
coast, that Japanese Americans (or Nisei) might commit acts of sabotage. In part, these
fears were racially-motivated, since there was no evidence that Japanese Americans were
any more disloyal than German Americans or Italian Americans. Nonetheless, in February
1942, President Roosevelt issued Executive Order 9066. This order permitted military
commanders to require Japanese Americans to relocate to interior internment camps away
from Western coastal regions. In these camps, Japanese Americans lived in primitive and
crowded conditions.

Forced Relocation of Japanese Americans

• The relocation raised constitutional issues in wartime. Roosevelt justified the

measures as a military necessity. The Supreme Court upheld the relocations in
Korematsu v. U.S. Korematsu was a Japanese American convicted of continuing to
remain in a restricted area. He believed his constitutional rights had been violated.
The Supreme Court upheld Roosevelt's order on the grounds that constitutional
liberties may be limited in wartime. Fifty years later, Congress apologized to the
interned Japanese Americans and voted to pay compensation to the families involved.

• During the war, a small number of German and Italian resident aliens were also

interned. About 2,000 German alien residents were forcibly sent back to Germany.
Germans were also sent from Latin America to the U.S. to be used in prisoner
exchanges with Germany.

War Turns Against Japan

•In 1943, the tide began to tum against Japan. The U.S. regained naval superiority in the Pacific and American forces
by "island-hopping"-- liberating Pacific islands from Japanese control, one at a time.

•Navajo Code Talkers:
▫One group of Americans who played a key role in the Pacific campaign were the Navajo code talkers. The
American military needed an undecipherable code to communicate that could not be broken by the Japanese.
The Navajo language is unwritten and extremely complex. By using this language, American forces could
transmit messages by telephone and radio in a code that the Japanese were unable to break.

•Battle of Midway:
▫The Battle of Midway was the turning point of the war in the Pacific. The Japanese were using their control of
the Western Pacific to protect their home islands and vast new empire. The Japanese Pacific fleet commander
had devised a plan to lure the U.S. Pacific fleet into a battle near Midway, a tiny mid-Pacific island, where he
believed he could destroy them. However, the U.S. Navy could decipher Japanese secret codes and knew that a
surprise attack by the Japanese fleet was at hand.

Bataan Death March, 1942

•In these same years, Americans remained at war with Japan. Geography played a critical role in
the Pacific campaign during World War II. The U.S. and Japan were separated by the vast Pacific
Ocean. After its attack on Pearl Harbor, the Japanese achieved quick victories in overrunning
Malaya, Burma, Indonesia, Singapore, Hong Kong, the Philippines, and the Western Pacific
Islands. They soon threatened Australia, India, Midway, and Hawaii.

•The Philippines faced an invasion by the Japanese army on the day Pearl Harbor was attacked. A
month later, U.S. and Filipino forces surrendered to the Japanese. The Japanese forced their
prisoners to undertake a 60-mile march through the jungle, which became known as the Bataan
Death March. These prisoners of war faced starvation, disease, exposure to the sun, and no
water. About 5,000 of the Americans, almost half, died along the way. Some were bayoneted,
shot, beheaded or just left to die along the side of the road.

Battle of Midway

•Admiral Chester Nimitz was appointed Commander-in-Chief of the U.S. Pacific Fleet just after Pearl
Harbor. He commanded U.S. forces at the Battle of Midway. During the Battle of Midway, the U.S.
destroyed four of Japan's aircraft carriers, effectively ending Japan's superior strength in the Pacific
Ocean. This battle halted the Japanese advance in the Pacific.

•The U.S. Army in the Pacific was commanded by General Douglas MacArthur. With additional
American reinforcements arriving, Nimitz and MacArthur began a campaign in the Solomon Islands,
which centered on taking Guadalcanal. The series of assaults on these Pacific islands drained Japanese
resources. Next, the Americans retook the Philippines and Guam. By June 1945, American forces had
captured Iwo Jima and Okinawa, islands close enough to be used as bases to launch attacks against the
Japanese home islands. Like the earlier invasion of Europe on D-Day, the assault on Okinawa was a
massive amphibious operation.

•Throughout the war, General George C. Marshall (1880-1959), acted as Chief of Staff and the
"organizer of victory." He worked closely with President Roosevelt to urge military preparedness before
Pearl Harbor, built up and supplied an army of 8 million men, and later helped to oversee the creation of
the first atomic bomb.

Decision to Use the Atomic Bomb

•In 1939, the famous scientist Albert Einstein sent a letter to President Roosevelt telling him it
was possible that Germany might be developing an atomic bomb. In 1942, President Roosevelt sent
a team of American scientists, several of them European refugees, to New Mexico, where they
developed and exploded the world's first atomic bomb in July 1945. By then, Germany had been
defeated, and America was preparing to invade Japan. President Roosevelt, re-elected a fourth time
in 1944, died suddenly of a heart attack in April 1945 -just before Germany had surrendered.

•His successor, President Harry Truman, feared that an invasion of Japan might lead to a million
American casualties. Truman preferred to use the atomic bomb against Japan rather than to
sustain such high losses. He selected centers of Japanese military production as targets.

•On August 6, an atomic bomb was exploded over the Japanese city of Hiroshima. Three days
later, a second bomb was exploded over Nagasaki. About 230,000 people were killed in both
explosions combined. Critics argued that Truman could have exploded bombs on unoccupied
islands in the Pacific as demonstrations, instead of on heavily populated cities. Japan surrendered
shortly after the second explosion, once American leaders agreed to allow the Japanese Emperor to
remain on his throne .

​The Holocaust in Europe

The Holocaust

• Genocide is an effort to murder an entire people or nationality. Part of Hitler's

Nazi philosophy was his intense hatred of Jewish people, on whom he blamed all
of Germany's problems. The Holocaust refers to the attempted genocide of the
Jews during World War II. After the outbreak of the war, Hitler and other Nazi
leaders decided to murder all European Jews. He called his plan the ''Final
Solution." At first, Jews were machine gunned next to open trenches they had
been forced to dig themselves, or gassed in trucks.

• When this method of extermination proved too slow for the Nazis, large

concentration camps were built across Europe. Jews from Nazi-controlled
countries were sent in cramped railroad cattle cars to these camps.

The Holocaust

• When they arrived in the camps, most were killed with poison gas and their

bodies were burned in large ovens. Some were spared to do the work of running
the camp. These inmates were half-starved and subjected to inhumane
conditions. About six million Jews -2/3 of those living in Europe - were killed
during the Holocaust. Six million gypsies, Slavs, political prisoners, elderly,
mentally-disabled, and others also died in Nazi concentration camps.

• During the last months of the war, the Allies advanced into Germany, where the

true horror of Nazi brutality was revealed. American army units were the first to
liberate concentration camps. They were shocked to see the half-starved,
dehydrated, disease-ridden prisoners.

​The Legacy of World War II

Legacy of World War II

•World War II was a global disaster of unprecedented dimensions. More than 70 million
people lost their lives.

•Denazification and the Division of Germany:
▫After the war, Germany was divided into four zones by the U.S., Britain, France, and the U.S.S.R..
Each occupied one zone. The occupying powers introduced programs explaining the evils of Nazi
beliefs to the German people. Hitler 's attempts to put his racist doctrines into practical effect also
played a large role in discrediting racism, anti-Semitism, Social Darwinism, eugenics, and similar
ideas worldwide. The Nazi nightmare showed where these ideas could lead. This contributed to the
later Civil Rights Movement in the U.S..

Legacy of World War II

• Occupation of Japan:

▫ General MacArthur, Supreme Commander of

Allied forces in the Pacific, was assigned the
task of rebuilding and reforming post-war
Japan. Under his leadership, important
changes were introduced to make Japan less
aggressive. Japan 's overseas empire was
taken away, and her military leaders were
put on trial and punished. Japan renounced
the use of nuclear weapons and the waging of
war. Japan was also forbidden from having a
large army or navy. A new constitution went
into effect in 1947, turning Japan into a
democracy.

• Technology in World War II:

▫ Some historians attribute the Allied victory

in the war to its many technological
advances. The atomic bomb was not the only
technological advance in World War II. The
war saw the emergence of many other
important technologies.

Technology in World War II

•Radar, an application developed during the war,
uses electromagnetic waves to detect a moving
object's range, altitude and direction. Sonar was
improved to detect submarines. Cryptic code
breaking allowed the Allies to find the meaning of
secret encrypted information, and later contributed
to the development of computers. Another major
technological breakthrough was the invention of
the proximity fuze- an explosive device that
automatically explodes when it is close to its target.
This greatly helped American forces fighting
Japanese aircraft and ships in the Pacific.

•One of the most important developments of the
war was the use of new antibiotics, such as
penicillin, to treat soldiers' battle wounds.
Discovered in 1928, penicillin was only mass-
produced for the first time in 1944 to treat soldiers
in the invasion of Normandy. Jet and rocket
engines, similarly developed before the war, now
saw their first real applications. The war was won
in part by the ability of the Allies to create new
technologies, all of which had lasting effects.

Nuremberg Trials, 1945 - 1946

• The liberation of concentration camps in Europe revealed millions of dead, along

with half-starved survivors. With the full extent of Nazi brutality revealed, the
Allies put surviving Nazi leaders on trial for "crimes against humanity" in
Nuremberg, Germany. Those on trial defended themselves by claiming they had
only been following orders. Many were found guilty of committing atrocities and
were hanged or imprisoned. The Nuremberg Trials demonstrated that
individuals are responsible for their actions, even in times of war .

Vernon Baker

• Vernon Baker was one of the first

African-American soldiers to see
combat in the war. In 1945, Baker
slipped through mine fields, barbed
wire, and German defenses to single-
handedly remove three machine gun
nests, two observation posts and two
bunkers. Baker emerged as a symbol
of the selfless sacrifice and courage of
African-American soldiers. Members
of his platoon nominated him for the
Distinguished Service Cross. It took
fifty-two years before President
Clinton finally awarded Baker the
nation's highest praise for battlefield
courage -- the Congressional Medal
of Honor.
