World War I: Introduction

Grade 8 · Social Studies · Study Guide

An introduction to the causes, major players, and key events of the First World War.

World War I, often called the Great War, lasted from 1914 to 1918 and involved most of the world's major powers. It was one of the deadliest conflicts in human history, killing approximately 17 million people.

Historians identify four main causes, remembered by the acronym MAIN: Militarism, Alliances, Imperialism, and Nationalism. European nations had been building up massive armies and navies for decades. They had also formed two major alliance systems: the Triple Alliance (Germany, Austria-Hungary, Italy) and the Triple Entente (France, Russia, Britain). These alliances meant that a conflict between two nations could quickly drag in all the major powers.

The immediate trigger for the war was the assassination of Archduke Franz Ferdinand of Austria-Hungary on June 28, 1914, in Sarajevo by a Serbian nationalist named Gavrilo Princip. Austria-Hungary blamed Serbia and issued an ultimatum. When Serbia's response was deemed unsatisfactory, the alliance system activated like a chain reaction.

The war introduced new and deadly technologies including poison gas, tanks, airplanes, and machine guns. Soldiers on the Western Front spent years in muddy trenches facing each other across a narrow strip of land called No Man's Land. This stalemate resulted in massive casualties with little territorial change.

The United States entered the war in April 1917 after German submarines attacked American ships and the Zimmermann Telegram was revealed. The U.S. entry helped tip the balance toward the Allies, and Germany signed an armistice on November 11, 1918.
