2014 marks the centennial of the start of World War I — DK will mark the occasion with the publication of World War I: The Definitive Visual Guide, a vividly illustrated, in-depth account of the Great War.

Written by historian R. G. Grant, and created by DK's award-winning editorial and design team, World War I charts the developments of the war from a global perspective. Using illustrated timelines, detailed maps, and personal accounts, readers will see the oft-studied war in a new light. Key episodes are set clearly in the wider context of the conflict, in-depth profiles look at the key generals and political leaders, and full-color photo galleries showcase the weapons, inventions, and new technologies that altered the course of history.

A vivid portrait of the confrontation on land, sea, and sky, World War I: The Definitive Visual Guide offers readers a bold and thoughtful new look at this complex and explosive moment in history.
