Who is Prince Babak Qajar?

The country is a democracy with an elected president as the head of the state. However, the province of Yogyakarta continues to be governed by a monarch who is styled as a governor for life under Indonesian law. Sultan Hamengku Buwono X is the current ruler, and thus the governor, of the Ngayogyakarta Hadiningrat Sultanate. Since the Sultan has no sons, he made his royal title gender-neutral with a decree in 2015, thus indicating that one of his daughters can succeed him. This has sparked controversy, with some people and members of the royal family reportedly unhappy about it.
