Updated content to commemorate the 100th anniversary of the end of World War I.

To commemorate the 100th anniversary of the end of World War I, Britannica invites you to explore our expanded coverage of the Great War.

To commemorate the 100th anniversary of the end of World War I, Encyclopaedia Britannica has created a new site experience to highlight our updated coverage of the war, including all-new features on women, African Americans, military technology, and life in the trenches. The intro to the portal reads:

“To its contemporaries, it was known simply as ‘the World War’ or ‘the Great War,’ because it was nearly impossible to imagine a conflict that would surpass the one that shattered Europe between July 28, 1914, and November 11, 1918. Combat and disease claimed the lives of more than 8 million fighting men, and 21 million more were wounded. As many as 13 million civilians died as a result of starvation, exposure, disease, military action, and massacres.

“Four great empires—the Hohenzollern, the Habsburg, the Romanov, and the Ottoman—fell, and the intercontinental movement of troops helped fuel the deadliest influenza pandemic in history. The ripple effects of the war, from the Great Depression, to World War II, to the Cold War, continue to be felt today.”
