Since February 24, 2022, Russia's full-scale invasion of Ukraine is ongoing. News of the fighting dominates Swedish media. As a consequence, Sweden has applied for NATO membership and new investments in national defense have been initiated. Swedish museums are working on export plans with renewed vigor, and issues of history and cultural heritage are higher on the agenda than they have been for years. What many people do not know is that there are exceptional objects from Ukraine in several museums and archives in Sweden. Strangely, these objects have never before been exhibited together in Sweden. Here is a unique opportunity to showcase and bring together historical artifacts of high relevance to research fields with touchpoints in both our history and the present. The Army Museum and the National Archives are working together with the National History Museums, the Ukrainian Embassy and the National Museum of Ukrainian History during the Second World War to produce a joint exhibition with the aim of spreading knowledge about the historical links between Sweden and Ukraine and thus problematizing the telling of history during war and conflict. The research collaboration is also an important support to Ukraine to strengthen cultural heritage institutions and assist in their resilience during ongoing war. It also develops our national knowledge on the protection of cultural heritage in war and strengthens the ability to collaborate with cultural heritage institutions in other countries. The societal relevance of the exhibition is very high and its implementation is urgent.
