The Contemporary World — First World War

Overview

'The First World War (1914–1918) was the FIRST INDUSTRIAL WAR — the first conflict fought with MACHINE GUNS, TANKS, POISON GAS, and AIRCRAFT. It DESTROYED four empires (German, Austro-Hungarian, Ottoman, Russian) and REDREW the map of Europe. ICSE examiners treat this as FOUNDATIONAL knowledge for understanding the 20th century — the war DIRECTLY led to the Treaty of Versailles, the League of Nations, and the RISE of DICTATORSHIPS in the 1930s.'


Causes of World War I

Long-Term Causes — The 'MAIN' Factors

FactorExplanation
M — MILITARISMEuropean powers COMPETED to build the LARGEST armies and navies. Germany and Britain had a NAVAL RACE (Dreadnought battleships). CONSCRIPTION became NORMAL
A — ALLIANCESTWO competing alliance systems: (1) TRIPLE ENTENTE — Britain, France, Russia. (2) TRIPLE ALLIANCE — Germany, Austria-Hungary, Italy (later switched sides)
I — IMPERIALISMRIVALRY for colonies in Africa and Asia. The MOROCCAN CRISES (1905, 1911) brought France and Germany to the BRINK of war
N — NATIONALISMINTENSE patriotism in every country. BALKAN NATIONALISM — Serbia, Greece, Bulgaria wanted FREEDOM from Austria-Hungary and Ottoman Empire. PAN-SLAVISM — Russia SUPPORTED Serbia.

Immediate Cause — The Sarajevo Assassination (28 June 1914)

AspectDetail
VictimARCHDUKE FRANZ FERDINAND — heir to the Austro-Hungarian throne
AssassinGAVRILO PRINCIP — a Bosnian Serb, member of the Black Hand (secret nationalist society)
LocationSARAJEVO, Bosnia
Austria's ResponseIssued an ULTIMATUM to Serbia — demanding CONTROL of Serbian investigation
Serbia's ResponseAccepted MOST terms — but Austria DECLARED WAR anyway

The Course of the War

The Schlieffen Plan (Germany)

Germany's plan to AVOID a two-front war:

  1. INVADE France through NEUTRAL Belgium (QUICK victory in the WEST)
  2. Then turn EAST to FIGHT Russia

Why the Plan Failed

  • Belgium RESISTED — delayed the German advance
  • Britain DECLARED war when Belgium was invaded (TREATY OF LONDON, 1839)
  • The FRENCH army and BEF (British Expeditionary Force) STOPPED the Germans at the MARNE (September 1914)
  • The war became a STALEMATE — TRENCH WARFARE on the Western Front

Key Features of the War

FeatureDescription
TRENCH WarfareSoldiers fought from TRENCHES — 'No Man's Land' between them
New WeaponsMACHINE GUNS, POISON GAS (chlorine, mustard), TANKS, AIRPLANES, SUBMARINES
Major BattlesVERDUN (1916) — 700,000 casualties. SOMME (1916) — 1 MILLION casualties. PASSCHENDAELE (1917)
U-Boat WarfareGermany used SUBMARINES to sink SHIPS. The LUSITANIA (1915) — 1,198 died
USA Enters1917 — Germany's UNRESTRICTED submarine warfare + ZIMMERMANN TELEGRAM pushed USA to DECLARE war
Russia Leaves1917 — BOLSHEVIK REVOLUTION. Lenin signed the TREATY OF BREST-LITOVSK (1918)

When the War Ended

  • GERMANY surrendered on 11 NOVEMBER 1918 (Armistice Day)
  • The KAISER abdicated — Germany became a REPUBLIC (Weimar Republic)

The Treaty of Versailles (28 June 1919)

The 'Big Three'

LeaderCountryPosition
Woodrow WILSONUSAWANTED a 'peace without victory' — based on his FOURTEEN POINTS
Georges CLEMENCEAUFranceWANTED REVENGE — make Germany PAY for the war
David LLOYD GEORGEUKIN-BETWEEN — wanted to punish Germany but NOT destroy it

Terms of the Treaty

CategoryTerms
TERRITORIALGermany LOST: Alsace-Lorraine (to France), Polish Corridor, all colonies. Saar coal mines to France for 15 years
MILITARYArmy LIMITED to 100,000. No TANKS, aircraft, submarines. RHINELAND DEMILITARISED. Navy restricted
FINANCIALREPARATIONS — 6.6 BILLION POUNDS (later reduced, finally paid off in 2010)
GUILTArticle 231 — 'WAR GUILT CLAUSE' — Germany ACCEPTED full responsibility for the war

ICSE Focus on War Guilt

'Article 231 was the MOST CONTROVERSIAL provision. Germans felt HUMILIATED — they were forced to accept BLAME for a war many believed was caused by ALL European powers. This humiliation DIRECTLY contributed to the RISE of HITLER and World War II.'


Wilson's Fourteen Points

Key PointsSummary
Open DiplomacyNO secret treaties
Freedom of the SeasFree navigation in peace AND war
Removal of Trade BarriersFree trade
DisarmamentREDUCE national armaments
Self-DeterminationColonial claims FAIRLY adjusted
League of NationsAn INTERNATIONAL organisation to PREVENT future wars
Specific TerritoriesSelf-determination for Poland, Belgium, France, Balkan states

'Only the LEAGUE OF NATIONS was FULLY implemented. The other points were IGNORED by the victorious powers — creating the CONDITIONS for World War II.'


The League of Nations (1920)

Aims

  1. To PREVENT future wars through COLLECTIVE SECURITY
  2. To promote INTERNATIONAL COOPERATION
  3. To enforce the TREATY OF VERSAILLES

Structure

OrganFunction
ASSEMBLYAll members — met ONCE a year
COUNCILMajor powers — PERMANENT members (Britain, France, Japan, Italy)
SECRETARIATAdministrative BODY
Permanent Court of International JusticeSettled international DISPUTES
Special AgenciesILO (labour), Health Organisation, Mandates Commission

Why the League Failed

ReasonExplanation
USA never JOINEDThe US Senate REFUSED to ratify the Treaty — the MOST powerful country was ABSENT
LACK of military forceThe League had NO army — could not ENFORCE decisions
UNANIMITY ruleALL members had to AGREE — made ACTION impossible
FAILURESManchuria (1931) — Japan invaded. Abyssinia (1935) — Italy invaded. The League did NOTHING

Key Dates

YearEvent

Common Mistakes in ICSE Answers

Forgetting the ASSASSINATIONThe Sarajevo assassination was the IMMEDIATE trigger
Ignoring the LEAGUE'S failuresThe League FAILED — this explains WWII
Treating Versailles as ONLY punishmentIt also created NEW nations (Poland, Czechoslovakia)
