Yogyakarta's sultan has five daughters and no son, and all 11 of his younger brothers opposed him when he raised the eldest toward the throne

Sultan Hamengkubuwono X has ruled Yogyakarta since 1989. By Javanese custom the throne passes to the eldest son. He has five daughters. Under a 2012 law the sultan is also governor of the province for five-year terms. In April 2015 he dropped the Muslim title "Khalifatullah", associated with male rulers, from his own style. He gave his eldest daughter, Ratu Pembayun, the title Ratu Mangkubumi, which he had himself held before he became sultan, and seated her in the chair kept for the crown prince. He told reporters that the succession would be settled later. All 11 of his younger brothers opposed him, led in public by Prince Yudhaningrat; five half-brothers came from Jakarta, heard his explanation and said they were not convinced. The 2012 law required a candidate for governor to list his "wife" among his family. Citizens challenged that wording. On 31 August 2017 the Constitutional Court, in decision 88/PUU-XIV/2016, struck out the phrase listing education, work, siblings, "wife" and children, removing the bar on a woman holding the office. In October 2017 President Joko Widodo reappointed the sultan governor. The throne has no proclaimed crown princess as of 2026^†.
