World War I: Causes and Consequences

World War I (1914-1918) was a devastating global conflict between the Allied Powers (France,

Britain, Russia, US, etc.) and the Central Powers (Germany,

Austria-Hungary, Ottoman Empire), triggered by Archduke Franz Ferdinand's assassination,

and marked by brutal trench warfare, new deadly technologies, and immense casualties (millions dead/wounded).

The war reshaped global politics, led to the fall of empires, and set the stage

for World War II, ending with the Central Powers' defeat and harsh treaties like Versailles.
