World War I: Causes, Key Concepts & Early Battles

TL;DR

World War I was triggered by a series of underlying tensions and one immediate event, quickly involving many nations due to complex alliances. Early battles like Mons showed the devastating impact of new technologies and trench warfare. The war eventually became "total war," changing economies and societies.

1. The Mental Model

Think of WWI as a massive, complicated domino effect. Many small, interconnected factors built up pressure, which then toppled all at once with a single, immediate trigger that pulled everyone into a global conflict.

2. The Core Material

Causes of World War I

WWI didn't happen overnight; it was the result of long-term tensions and one "immediate cause." These are often remembered using the acronym "MAIN":

• Militarism: This was a build-up of military strength and a belief that military power was the best way to solve international problems. Countries were preparing for war.
• Alliances: European countries formed complex defense agreements, meaning an attack on one country could drag many others into conflict.
• Imperialism: Nations competed for colonies and resources around the world, leading to rivalries and conflicts over territory and influence.
• Nationalism: Intense pride in one's own country, often accompanied by a desire for self-rule or dominance over other groups, fueled ethnic tensions and rivalries.
• Immediate cause: While not specified in your notes, the immediate cause that sparked the war was the assassination of Archduke Franz Ferdinand of Austria-Hungary in June 1914.

Early Battles & Strategy

The war started with quick movements but soon bogged down.

• Schlieffen Plan: This was Germany's war plan to quickly defeat France by invading through neutral Belgium before Russia could fully mobilize. The plan's execution, specifically the invasion of Belgium, led Britain to declare war on Germany.
• Battle of Mons: This was one of the first major British battles of WWI. It was an early WWI battle where British forces engaged the advancing German army.

Why WWI Battles Were So Bloody & Trench Conditions

The combination of new technology and old tactics led to incredibly high casualties and a brutal style of warfare.

• Machine guns and artillery: These powerful new weapons caused immense destruction and made frontal assaults extremely costly.
• Trench warfare stalemate: Both sides dug extensive trenches, leading to a static front line where neither side could advance easily. This created a stalemate.
• Barbed wire and no-man’s-land: The areas between opposing trenches were filled with barbed wire obstacles and were known as "no-man's-land," making attacks across it deadly.
• Mud, rats, disease: Life in the trenches was horrific, characterized by unsanitary conditions, constant exposure to the elements, and widespread disease.
• Constant shelling and attacks: Soldiers faced continuous bombardment and repeated, often futile, assaults.

How Canada Got Involved

Canada's participation was directly linked to Britain's entry into the war.

• When Germany invaded Belgium as part of the Schlieffen Plan, Britain declared war on Germany.
• As a member of the British Empire, Canada automatically joined the war.
• Canadian troops were quickly sent to Europe.

Canadian Emergency Powers

• War Measures Act: This was a Canadian emergency law enacted during WWI that significantly expanded the government's power. It allowed the government to bypass Parliament and control various aspects of Canadian life (e.g., censorship, detention without trial).

Canada's Contribution

While some of your notes touch on WWII contributions, for WWI, Canada quickly sent troops and later built a strong reputation.
* Aboriginal Canadians were valued as Scouts & Snipers due to their skills.
* William Barker was Canada’s most decorated war hero.

Total War / Global War

WWI demanded unprecedented effort from entire nations.

• Entire economy used for war: Countries directed all their industrial and economic resources towards the war effort.
• Civilians supported war effort: Citizens on the home front were crucial, working in factories, conserving resources, and buying war bonds.
• Governments controlled production: Governments took immense control over industries to ensure war materials were produced efficiently.
• Fighting on many continents: While primarily fought in Europe, the war involved fighting in colonies and other regions globally.
• Many countries and colonies involved: The vast empires of the involved nations meant the conflict truly spanned the globe.

Impact on Ordinary Canadians

The war brought significant changes to Canadian society.

• War industries increased: Factories shifted to producing war materials, creating many new jobs.
• Women worked in factories: With men away fighting, women stepped into roles traditionally held by men, particularly in industrial jobs.
• Government controls and propaganda: The government used propaganda to rally public support and exerted more control over daily life.
• Food rationing and higher taxes: Resources were conserved for the war, leading to rationing of goods and increased taxes to fund the war effort.
• Women gained voting rights: Their significant contribution to the war effort helped accelerate the movement for women's suffrage.

End of WWI: Treaty of Versailles

The treaty that officially ended WWI left a lasting impact.

• Treaty of Versailles: This was the main treaty ending WWI.
• Germany accepted war guilt: Germany was forced to take full responsibility for starting the war.
• Lost territory and colonies: Germany had to give up significant land and all its overseas colonies.
• Military limited: Its armed forces were severely restricted in size and capability.
• Paid large reparations: Germany was ordered to pay huge sums of money to the Allied powers for war damages.
• Treaty considered harsh and unstable: Many historians believe the harsh terms imposed on Germany contributed to future instability and ultimately, World War II.

3. Worked Example

Let's trace how the "immediate cause" connected to Canada joining the war through the "Alliances" and "Militarism":

1. Immediate Cause (Assassination): The assassination of Archduke Franz Ferdinand (though not listed in your notes as the name of the event, it is the classic example of an "immediate cause") sparked tensions between Austria-Hungary and Serbia.
2. Alliances: Due to existing alliances, Russia backed Serbia, and Germany backed Austria-Hungary. This quickly drew more nations into the conflict when declarations of war began.
3. Schlieffen Plan & Militarism: Germany, driven by its military planning (Militarism), activated its Schlieffen Plan to defeat France quickly by invading neutral Belgium.
4. Britain's Entry: The invasion of Belgium triggered Britain to declare war on Germany.
5. Canada's Entry: Because Canada was part of the British Empire, it automatically joined the war when Britain did, sending Canadian troops to Europe to fight.

This chain of events shows how a single incident, combined with pre-existing alliances and military plans, rapidly escalated into a global conflict involving Canada.

4. Key Takeaways

• WWI's main causes were Militarism, Alliances, Imperialism, and Nationalism (MAIN), with one immediate spark.
• The Schlieffen Plan was Germany's strategy to quickly defeat France by going through Belgium.
• Early battles, like Mons, demonstrated the brutal impact of new weapons and trench warfare.
• Trench warfare created a deadly stalemate, characterized by mud, disease, and constant shelling.
• Canada joined WWI automatically when Britain declared war on Germany after the invasion of Belgium.
• The War Measures Act gave the Canadian government extensive powers during the conflict.
• WWI became a "total war," requiring entire nations to contribute all their resources and citizens' efforts.
• The Treaty of Versailles required Germany to accept war guilt, lose territory, limit its military, and pay reparations.

Common Mistakes to Avoid:
* Confusing the immediate cause (assassination) with the long-term causes (MAIN).
* Thinking Canada chose to enter the war independently in 1914, rather than doing so via its ties to Britain.
* Underestimating the role of technological advancements in making WWI so bloody.
* Forgetting that the Treaty of Versailles' harshness contributed to future problems.

5. Now Try It

Imagine you are an ordinary Canadian citizen in 1915. Using the notes provided, describe three specific ways the war would have impacted your daily life, and how you might feel about the government's new powers under the War Measures Act. What specific war material might you be helping to produce or conserve?

Success looks like: Mentioning specific impacts (like rationing, women working in factories, or controlled production), expressing a plausible feeling about government power (e.g., support for the war effort vs. concern for rights), and identifying a relevant material from the notes (e.g., food, uniforms, steel).
