🔥 Causes of World War I
Although the war started with one assassination, the real causes were deeper and more complex. Historians describe the main causes with four key factors:

1️⃣ Militarism
European nations had been building massive armies and weapons. Military pride and power made nations ready for war.
2️⃣ Alliances
Europe was divided into two powerful alliance systems:
Triple Entente (Allied Powers): France, Russia, Britain
Triple Alliance (Central Powers): Germany, Austria-Hungary, Italy
These alliances meant that a conflict between two countries could drag many more into war.
3️⃣ Imperialism
European powers competed for colonies in Africa and Asia. This competition created tension and rivalry.
4️⃣ Nationalism
Strong nationalism encouraged countries to prove their power.
In the Balkans, especially Serbia, nationalism was extremely high.
🕊️ The Assassination That Sparked the War
On June 28, 1914, Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, was assassinated in Sarajevo by a Serbian nationalist.
Austria-Hungary blamed Serbia and declared war.
Within days, alliances activated, and the entire continent was at war.
⚔️ Major Powers in the War
🌐 Allied Powers
France
Britain
Russia (until 1917)

🛡️ Central Powers

These nations fought across Europe, Africa, the Middle East, and the oceans.

🕳️ Trench Warfare: Life in the Trenches
Most battles took place on the Western Front, where both sides dug deep trenches.
Life in the trenches was extremely hard:
Mud and water everywhere
Rats and disease
Constant fear of attacks
Artillery shelling day and night
Very slow movement of front lines
This war introduced new technologies:
Machine guns
Poison gas (chlorine, mustard gas)
Tanks
Submarines (U-boats)
Heavy artillery
Early aircraft
These inventions made World War I unlike any war before.

🇺🇸 The United States Joins the War (1917)
At first, the U.S. stayed neutral.
But Germany’s submarine attacks on American ships forced the U.S. to join the Allies in 1917.
American troops brought:
Fresh soldiers
Money
Supplies
This gave the Allies a powerful advantage.

❗ Russia Withdraws (1917)
In the same year, Russia left the war because of the Russian Revolution.
The new government signed peace with Germany.
But the loss of Russia was balanced by the arrival of the U.S.

🕊️ The End of the War
On November 11, 1918, Germany requested an armistice.
This date is now remembered as:
