The ostrich feather shown here was part of the crown worn by Zulu King Cetshwayo at his installation in 1873; the framed photograph shows the crown, which included feathers dyed crimson. The pen which sits alongside was used by Zulu leaders on 1 September 1879 to sign the Treaty of Ulundi which concluded the Anglo-Zulu War. After this King Cetshwayo was sent into exile and Zululand was divided into thirteen independent chieftainships.
