Indonesia, received by President Joko Widodo. Today considered as Indonesian national hero, Prince Diponegoro of Yogyakarta was the charismatic leader of the mass rebellion against Dutch colonial rule in Central Java, that was defeated and taken prisoner after the conclusion of Java War in 1830. His kris was long considered lost, but has now been found, after being identified by the Dutch National Museum of Ethnology in Leiden. The extraordinary gold-inlaid Javanese dagger previously was held as the Dutch State Collection, and is now part of the collection of the Indonesian National Museum.
