The sources for the First World War held by The National Archives and the Imperial War Museum offer richly varied insights into all aspects of what H G Wells called 'the war that will end war'.

By making a selection of these records available online for the first time, this exhibition provides a valuable research tool for all those interested in modern history - including anyone tracing military records of ancestors who served in the First World War or researching controversies relating to the conflict.

Beyond that, it aims to create a wider understanding of the global nature of the war and its consequences, which in areas such as the Balkans and Palestine are still being felt today.
