Choosing sides and war plans

The First World War

• Product of Multiple Factors:• Militarism • *development of naval arms race

• Alliances*agreement to protect one another*Alliance System – existed prior to the war

• Imperialism• *Industrialization & Imperialism went hand in hand • Nationalism • *National interest should come ahead of global

Alliance System:

Triple Alliance

1. Austria-Hungary

2. Germany

3. Italy

Triple Entente

1. Great Britain

2. Russia (Serbia)

3. France

The Balkins 1914

Balkin Peninsula-“Powder Keg of Europe”

Archduke Franz Ferdinand & His Family

June 1914 – Archduke Ferdinand, heir to the Austria-Hungarian throne, and his wife, Sophie, were assassinated in Sarajevo, Bosnia.

The Assassination

The Immediate Cause of the War:

* Gavrilo Princip• A teenage member of the secret society Black Hand

was the assassin• The society’s aim was to unite all Serbians

• July 28, 1914 – Austria blamed Serbia, who was allied with Russia. Austria declared a “bright, brisk little war” against Serbia • This forces the alliance system into effect.

• August 1, 1914 – Germany declares war on Russia.• This draws France and Great Britain into the war.

The Assassin

Gavrilo Princip

Most of the World Was Divided Into 2 Groups:

Central Powers

1. Germany

2. Austria-Hungary

3. Ottoman Empire

Allied Powers.

1. Russia

2. Great Britain

3. France• More than 20 other

nations eventually joined, including.

Italy and the U.S.

Area 2

Strategy

1. Schlieffen Plan

• Alfred von Schlieffen developed a plan to defend Germany against France & Britain• Needed to defeat France before Russia

was able to arm themselves• Attach France from the north through the

low lands

Fronts – combat zones, many small wars fought at once.

• Europe was divided into two fronts:• Western• Eastern

Western Front:• Northern France and Southern Belgium

• France and Britain vs. GermanyThis map shows the Western Front. The battlefields (shown in gray) are located along a 450 mile stretch and run across many different types of ground. The Northern end of the front began on the sandy dunes of the Belgian coast. It continued south through northern France then east through the provinces of Lorraine and Alsace, both then occupied by Imperial Germany, finally terminating on the Swiss border in the south.

Location of Trenches

Two parallel trench lines running from the North Sea all the way to the border of Switzerland.

WOW!

• If all of the trenches constructed during World War I were laid end to end, they would cover 25,000 miles!

2. Trench Warfare:• Soldiers dug long trenches protected by mines and

barbed wire.• Front Line: Brunt enemy attacks• Reserve Line: When Front Line was overwhelmed, the

troops in the reserve trench would be used as support• Support Line: Mainly used to rest troops although

could be called upon to help in a crisis.• Sap / Fire trenches – went into no-man’s land. Very

dangerous.• All the trenches were linked by communications

trenches.

Cross Section of a Trench

Trench Warfare

Trench Warfare Continued:• Each trench – 10 feet deep• Fire Step – a ledge halfway up the trench, where

people would shoot from. • Dugout - holes dug into the sides of the trench used

for sleeping.

Trench Warfare

Problems of Trench Warfare

Trench Foot

• 1000’s of soldiers were killed in battles that won very little territory.• November 1914 there was a stalemate.

• Stalemate – a situation in which no one can win

Area 3

Weapons of War

New Weapons:

• Machine Guns• Poisonous Gas• Tanks• Aircraft (Balloons)• Submarines / U-Boats

• Resulted in a different type of war•Mechanized Warfare

Poison Gas

• Chemical warfare, used by both sides, made gas masks necessary
