Stages of Historical ConsciousnessHistory as fact• “This happened.”
History as causal sequence• “Why did this happen?” “What happened
before/after?”History as complexity• “How does this fit into a wider scope of
regional/world events?”• “Are there larger ‘patterns’ this fits into?”
History as interpretation• People make things happen – What people made
this happen? Why did they make it happen?
Causes of War
Causes of War, World War I
• Entangling Alliances & their consequences– Dual Alliance (1879) – Germany & Austria– Triple Alliance (1882) – added Italy– Dual Entente (1893) – France & Russia– Entente Cordial (1904) – Brits & FR ‘make nice’ …– Anglo-Russian Entente (1907) – Brits & RUS turn– Triple Entente is now formed – FR, RUS, UK
• Causes of Militarism/Nationalism• Germany’s Weltpolitik (Schlieffen Plan)
Causes of War, World War I
• Militarism/Nationalism – Austria• Militarism/Nationalism – Italy• Militarism/Nationalism – Russia• Militarism/Nationalism – France• Consequences – War was inevitable ???• Domestic factors– Germany (Kaiser needed to prove his ‘manhood’?)– Austria-Hungary (needed to ‘unite’ ethnicities)– France (hating on Germany!!!)
Causes of War, World War I
• Imperialism– They ‘needed’ more stuff!– Places / resources / power
• Italy & Germany possessed no colonies and they wanted ‘in’ on the land grab game!!!
• Austria-Hungary wanted Balkans• Germany hating on the Brits• Russia is insecure & wants to increase
influence in Turkey (straits) & Balkans, too!
Causes of War, World War I• Brits & FR rule … but feel their power ‘declining’ …• Brits –– The Middle East market was threatened by Germany
and Italy– The China market was being lost to the U.S. and Japan
• FR –– Although France was really declining, French
governments followed well-thought out expansionist aims overseas and refused to be intimidated
– They added to the empire in North Africa (Tunis was added to Algeria) and in eastern Asia in Indo-China
– Until 1903, Britain blocked French imperial ambitions; FR hated Britain, too!
Causes of War, World War I• Causes of the War• The “isms”– Nationalism– Imperialism–Militarism

Unit 1: Causes of War, World War I
• Balkan Wars• Growing Russian Support of Serbia• The Assassination• Austria-Hungary believed that:– Serbia and Russia would be restrained by Austrian
diplomacy backed by Germany– Russia was utilizing Balkan discontents against
Austria-Hungary– A diplomatic offensive was no longer enough– Serbia needed to be “punished or the empire’s
role as a great power would be at an end”– If they could prove that Russian protection could
not save Serbia from Austria-Hungary’s wrath, the lesson would not be lost on the other Balkan states
Causes of War, World War I
• Blank Check– AH gives Serbia an Ultimatum … to which Serbia
complies (except for Austrian rule) – but war is declared anyway July 28, 1914
• On August 1st, 1914, war was declared on Russia

dominant tone– Article 231 – “War Guilt Clause” – Germany had to
accept everything as their fault• Great Depression– Destroyed the positive and encouraging economic
and political developments of the years between 1924 and 1930
Causes of War, World War II
• The Great Depression – Debts & Reparations• Dawes Plan 1924• Created a cycle:– U.S. banks loaned money to Germany– Germany paid reparations to France and Britain– France and Britain paid war debts to the U.S.
Isolationism in Britain, SERIOUS economic problems in Germany!!!
Causes of War, World War II
• Failure of the WEIMAR REPUBLIC• Rise of HITLER!!!• Spread of FACISM • Hitler & Mussolini• Aryanism & Lebensraum• Policy of Appeasement – the granting
concessions to potential enemies to maintain peace
• BR & FR reasons to ‘appease’ …

psychological tensions between peoples– Propaganda and coercion– Prestige and material interests– Appeasement and confidence
Causes of War, World War II
• Remember MAIN!!!• Militarism (naval build up/remilitarization)• Alliances (entaglement!!!)• Imperialism (colonialism/neo-colonialism)• Nationalism (in particular w rise of Hitler!)
Effects of War, WWI
• Discussed Economic Effects first – biggest!!!• Blockades• Britain and Germany relied heavily on imports
to feed the population and supply the war industry
• Since Britain had a superiority of naval vessels, Germany’s only chance to compete was through U-boats
• They used unrestricted submarine warfare to sink any ships in the area of Britain
Effects of War, WWI
• Effects in Germany:– 750,000 German civilians died of starvation during and
after the war– blockade continued until June 1919 in order to force the
Germans to sign the Versailles Treaty• Sinking of the Lusitania & the Zimmerman Telegram
(if Mexico were to join Germany in an alliance, they would get Texas and Arizona in return) brought US into war
• Deaths – Russia suffered THE MOST! Followed by Germany …
Effects of War, WWI• Devastation In Belgium; France; the Balkans, Middle
East, and Italy; Africa and the Pacific• Rise of the United States• Inflation is the greatest single economic factor
because of massive– War budgets– Demand, which caused shortages of many consumer goods– Virtually every able-bodied person was employed to keep up
with the demand• When resources became scarce, nonessential firms,
which tended to be small, were simply closed down• This combination of high demand, scarcity, and full
employment sent prices soaring, even in the best managed countries
Effects of War, WWI
• Results of inflation were:–Value of money went down–The standard of life went down–People living on fixed incomes or small
earnings were hurt the most• Had to plant gardens for food• Had to take odd jobs like repairing
clothes
Effects of War, WWI
• Dawes Plan (& subsequent Young Plan) both failed!!!
• Both were designed to help Germany meet its reparation payments– The U.S. would lend money to Germany; Germany
would make reparation payments to Britain and France; Britain and France would pay back loans to the U.S.
– This made the countries dependent on the U.S.• Defaults led to Great Depression & rise of
extreme nationalism!
Effects of War, WWI
• Social effects• Disillusionment (All Quiet on the Western
Front)• Trench warfare• Shell Shock• Development of arms race / arms
manufacturers became major enterprises• Effects of rationing• Effects on women (rise of public employment)

war. It became acceptable for young, employed, single middle-class women to:– Have their own apartments– Go out without chaperones– Smoke in public– Women's skirts rose above the ankle permanently
• Effects on African Americans• Growth of Labor Unions
Effects of War, WWI
• Restrictions of Civil Liberties during war• Propaganda• Armenian Genocide• Influenza
Moved on to Effects of War, WWIIStarted w effects on Germany & USSR

women were raped, often repeatedly …• Women were “seen” as collaborators &
ostracized from society (FR & DEN)• Holocaust– By May 1945, every 2 out of 3 Jews were murdered– A total of 6 million Jews were killed, along with 2
million others– Communists, Jehovah’s Witnesses, Roma and Sinta
(gypsies), Socialists, trade unions, homosexuals, Polish and Soviet dissidents, and the mentally and physically disabled were also in the Holocaust
Effects of War, WWII
Germany:• 3 million soldiers killed or missing• ½ million civilians killed• Millions more wounded and disabled• Parts of cities were totally flattened• No key industry had suffered more than 20%
losses• Conditions were BAD post war in GER!!!

several countries after the war• An estimated 500,000-3 million died in the
expulsion• Rehabilitation of Nazis (re-education)• Nuremburg Trials• German Occupation
Effects of War, WWII
Soviet Union• Relaxed their ideology to maximize the war
effort• Propaganda appealed to “Mother Russia”
rather than communism• Soldiers could not talk with local populations• Captured Russian soldiers, when repatriated,
were sent to the Gulags or simply shot• Rigid censorship in newspapers was imposed
Effects of War, WWII
Soviet Union: Origins of the Cold War• Different philosophies/ideologies:– Democratic capitalism– Marxist communism
• The Western Allies had appeased the growing power of Hitler partly in the hope that he would destroy the Soviet state for them
• The USSR had been supplying the Luftwaffe with aircraft fuel with which to fight the Battle of Britain and to bomb British cities in the Blitz
• Delays in opening a second front angered the Soviets
Effects of War, WWII
Soviet Union• From the scorched earth policy:– 25 million were homeless– Factories were destroyed– Railways disrupted– Farm machinery was almost non-existent
• 21 million died• 1 in 4 Russians were killed or wounded• Lend-lease aid from the U.S. was ended in August
1945• Reparations were exacted from the Soviet zones of
Germany and Austria
Effects of War, WWII
Soviet Union• The Soviets wanted Poland because:–Russia wanted a buffer area because they
had been invaded many times:• 1 time by the French• 2 times by the Germans• 1 time by the Poles
• The Soviets then installed a Polish Communist government
Effects of War, WWII
• Eastern Europe disappeared from Western sight behind the “iron curtain” of secrecy and isolation– East Germany– Poland– Czechoslovakia– Hungary– Romania– Bulgaria– Finland– Yugoslavia– Albania
Effects of War, WWIIBritain• Britain’s financial situation was dependent on
U.S. lend-lease aid• Gave up colonies• Formation of Israel– British controlled Palestine was given the Jews to
establish a safe haven and homeland• Greek Civil War (1944-49)– British troops liberated them in 1944– Most of the Greek people didn’t wish to return to pre-
war political and social conditions, so they supported the EAM – a communist Greek National Liberation Front
Effects of War, WWIIFrance• Grave shortages of food and fuel• Infrastructure devastated• Mandates of Syria and Lebanon were given
independence during WWII• It was policy to draw a veil over the Vichy years
to conciliate and unite the nationItaly• The perception of Italians was better than the
Germans because they entered on the side of the Allies and didn’t commit atrocities on the scale of the Germans
Effects of War, WWII• US• Not so bad off …• Truman’s Fair Deal• Japanese internment• GI Bill – Provided federal grants which gave soldiers
money for college, to start new small businesses, or build a new home
• Baby Boom – Caused an growing need for educational resources
• Interstate Highway System – Would be created under Eisenhower’s administration because he saw it as a way to move military supplies around the country quickly. He got the idea from his wartime experiences in Europe (Autobahn)
Effects of War, WWII
• Origins of the Cold War• Atomic bomb• The Marshall Plan• Aid through the Marshall Plan was intended to create strong
democracies and open new markets for American goods• The Soviet Union was invited to join, but refused
– Americans were buying their way into European affairs– Would’ve had to accept it on difficult terms – making vast political
reforms and have outside controls– They discouraged their satellite nations from joining as well
• Occupation of Japan
Effects of War, WWII
• Psychological, social effects of WWII• Women, minorities, economics• End of European domination, “myth of white
supremacy” in the eastern part of the world
Single Party States
• Hitler, Lenin, Stalin = EUR• Mao = ASIA• Castro = AMERICAS
