Хаменгкубувоно IX
Hamengkubuwono X succeeded his father, Hamengkubuwono IX as the Sultan of Yogyakarta when Hamengkubuwono IX died on 3 October 1988. Hamengkubuwono X was formally installed as Sultan on 7 March 1989. However, the position of the Governor of the Yogyakarta Special Region did not go to Hamengkubuwono X. Vice Governor Sri Paku Alam VIII, prince of the subordinate enclave of Paku Alaman within Yogyakarta was instead controversially elevated to the position of governor. This was contrary to the agreement made at the independence of Indonesia in recognition of Hamengkubuwono IX's support and role in the Indonesian War of Independence. Under the agreement, the Sultan holds the position of governor in the Yogyakarta Special Region, and the Paku Alam holds the position of vice governor.
