Causes of World War I: Key Events and Factors




The Powder Keg: Long-Term Causes of WWI
Think of Europe before 1914 as a group of overly competitive mates who couldn't stand each other. Nationalism made every country believe they were absolutely brilliant whilst everyone else was rubbish - not exactly a recipe for friendly relations!
Meanwhile, imperialism had nations scrambling to grab as much land and resources as possible around the world. It was like a massive game of Monopoly, except the stakes were real colonies and everyone was cheating.
The arms race made everything worse. When one country built bigger guns, everyone else panicked and built even bigger ones. Soon, Europe was armed to the teeth and looking for an excuse to use all those shiny new weapons.
Remember: These long-term causes created the perfect storm - all Europe needed was a spark to set everything off!

The Spark: Short-Term Causes and Alliances
The assassination of Archduke Franz Ferdinand on 28th June 1914 was that fatal spark. A Serbian nationalist shot the heir to the Austrian throne in Sarajevo, giving Austria-Hungary the perfect excuse to crush Serbia once and for all.
Here's where the alliance system turned a local dispute into a world war. The Triple Alliance faced off against the Triple Entente (France, Russia, Britain). When Austria declared war on Serbia, Russia had to back Serbia, Germany had to support Austria, and France had to help Russia.
Britain's involvement came through Germany's Schlieffen Plan - a strategy to quickly knock out France by attacking through Belgium. Since Britain had promised to protect Belgian neutrality, they had no choice but to join the fighting.
Quick Tip: Think of the alliances like a domino effect - once one fell, they all had to fall!

The Countdown to War: July-August 1914
The final month before war broke out moved incredibly quickly. 28th June 1914 - Franz Ferdinand was shot dead in Sarajevo by a Serbian nationalist, sending shockwaves across Europe.
Exactly one month later, 28th July 1914, Austria-Hungary declared war on Serbia. Russia couldn't let their Slavic allies down, so they mobilised their army on 30th July. This terrified Germany, who declared war on Russia just two days later.
The dominoes kept falling rapidly. 3rd August 1914 saw Germany declare war on France and launch their Schlieffen Plan through Belgium. Within a week, a single gunshot had pulled the major powers of Europe into the most devastating conflict the world had ever seen.
Key Point: Once the mobilisation started, there was no stopping it - the alliance system made war almost inevitable!
