The First World War began in central Europe in late July 1914. There were many factors that led Europe to war, such as the conflicts and hostility between the great powers over the previous four decades.

The immediate origins of the war, however, lay in the decisions taken by statesmen and generals during the July Crisis of 1914. This crisis was caused by the assassination of the Austrian Archduke Franz Ferdinand by Gavrilo Princip, a member of a Serbian nationalist organisation.

Below you'll find a series of articles that explore the origins of the war. Read about Franz Ferdinand's assassination, discover the diplomatic crisis that engulfed Europe in July, explore Germany's strategic war plans, and lots more. We've suggested an order for you to read, but feel free to dip in and out wherever you like.
