Since its foundation in 1917 IWM has been building its collections in order to illustrate and record all aspects of conflict in the twentieth and twenty-first centuries. We want our collections to continue to engage, challenge and remain relevant to our audiences, and we need to safeguard it for future generations.

IWM’s collection covers all aspects of conflict involving Britain, its former Empire and the Commonwealth, from the First World War to the present day. As well as objects, it includes a range of media, from artfilm and photographs to printed materials, documents and sound.

Building our collections

Curatorial departments
Our unparalleled and unique collections stretch from the everyday to the exceptional and contain some of the most important technical, social, economic, political, personal and cultural artefacts relating to Britain and its role in conflict since 1914.  Through research and interpretation, our curators seek to unlock the multiple stories held within the collection.

Recent acquisitions
Items in our Collections come from many sources, from artists and members of the public through to government departments and military personnel.
Donate objects to the collection
Donated objects are recorded, preserved and cared for to the highest standards. However, this comes at a high cost, forcing us to be selective about what we can now accept into our keeping.

Care and Conservation
The effective care of collections is central to the work of IWM. Collections care is the responsibility of all our staff, but a specialised care team exists to provide support and guidance across the organisation. Proper care ensures the preservation of our unique collections for future generations.

Warship Conservation
HMS Belfast joined the Imperial War Museums collection in 1978, becoming a museum and also the largest item in our collection. As both a historical object and museum its needs are unique and it requires constant conservation work.

Collection development

Afghanistan - War Story Collection
Developing our collections information
IWM has been collecting for over 100 years. Our collection of over 33 million items tells the stories of how war and modern conflict has impacted people. Looking back at what we have collected we realise our collection, and how we talk about it, isn’t as representative as we’d like it to be. We are working to change that. Find out more about our collection and our policies.
