The digital collection (Ex-)keizer Wilhelm II [(Ex-)emperor Wilhelm II] has been created by Het Utrechts Archief, the combined municipal archives of the city Utrecht and the state archives in the province Utrecht. In November 1918 the German emperor fled from the German army headquarters in Spa to the Netherlands. Initially he stayed at castle Amerongen. In 1920 he moved to the estate of Huis Doorn, now a museum. The emperor succeeded in getting a generous selection of his belongings in Germany to Huis Doorn. The Kaiser died in 1941. After the Second World War the Dutch authorities confiscated his goods. In 1975 the archival collection was transferred to Het Utrechts Archief.
The digital collection is essentially an online finding aid with digitized materials. Het Utrechts Archief offers a general introduction (in Dutch) to this collection. The collection has been divided into personal papers (stukken van persoonlijke aard), business and estate materials (stukken van zakelijke aard), materials before 1918, documentation and maps (Kaarten). Section 5.2 of the maps contains some ninety maps dealing with the First World War. You will find digitized letters, books, journals and newspapers, and various other materials, some of them from the nineteenth century. You can consult a German version of the finding aid, created in 1997 at the time the collection was microfilmed.
