Short answer: World War I was caused by a mix of long-term tensions in Europe (militarism, alliances, imperialism, and nationalism) plus an immediate trigger — the assassination of Archduke Franz Ferdinand of Austria in 1914. Those factors together turned a local crisis into a continent-wide war.

Explain it for 8th grade:

- Militarism: European countries built up large armies and navies and were ready to use them. This made leaders more likely to solve problems with force.

- Alliances: Countries formed defense agreements (for example, Germany and Austria-Hungary; France and Russia; Britain was tied to Belgium and had ties with France). These made a small conflict likely to spread, because allies were bound to help each other.

- Imperialism: Major powers competed for colonies and resources around the world (especially in Africa and Asia). This competition created rivalries and distrust.

- Nationalism: People felt strong loyalty to their own nations or ethnic groups. Some peoples wanted independence (especially in the Balkans), and national pride made countries unwilling to back down.

Immediate spark:
- On June 28, 1914, Archduke Franz Ferdinand of Austria-Hungary was assassinated in Sarajevo by a Bosnian Serb nationalist.
- Austria-Hungary blamed Serbia and issued an ultimatum. When Serbia didn’t fully accept all demands, Austria-Hungary declared war on Serbia (July 1914).
- Because of the alliance system and mobilizations, Russia moved to defend Serbia, Germany declared war on Russia, then on Russia’s ally France, and Germany invaded Belgium to reach France. Britain declared war on Germany after the invasion of neutral Belgium.
- In weeks the war involved most of Europe and then spread worldwide.

Think of it like a powder keg (all the long-term tensions) and a spark (the assassination) that set it off.

Short summary: Multiple deep rivalries and military preparations made Europe unstable, and the assassination in 1914 triggered a chain reaction of alliance commitments and mobilizations that led to World War I.
